Review: Sumiko Speaker Set Speaker

Category: Speakers

Wow, I just accomplished the single most impressive step forward in my system after 40+years of audiophilia. I had my speakers set using the system developed my Sumiko so that its dealers can optimize the set up of speakers they sell.

Those that remember me please forgive me for repeating my background, but on a forum like this there are always newbies that don’t really know the reviewers’ points of view, so let me give a little background as to my music and audiophile experience. I’m a financial consultant by trade, with over thirty-nine year’s experience, but I have over fifty-years experience as a “serious” musician. I’ve played trumpet since I was nine and jazz guitar since I was forty-two. I write equipment reviews (amps, guitars and speaker cabinets) for Just Jazz Guitar, play rhythm guitar in a big band and play trumpet regularly in churches, regional symphonies, brass bands (cornet of course) and even did a multi-year stint as lead trumpet in a funk/rock/soul band in the Dallas area. I hear live music all the time in tons of different contexts. For instance, on Thanksgiving eve I played trumpet with a large choral group and then had the pleasure of sitting there right next to a harp/oboe/flute trio accompanying the same choir. I’ve been really blessed to play in some incredible groups, including just recently, the Colorado Brass Band, one of the premier bands of the genre in the USA. I’ve played orchestral trumpet sitting with my back against the wall hiding a 32-foot organ pipe that massaged my whole body as I played. So, I feel and hear the music regularly.

I’ve really been serious about audio since my college days, when I bought my first Garrard/Scott/Jensen system. I moved to Time Windows/Bryston in the 1970s and 1980s and replaced the DCMs with Celestions mini-monitors in the 1980s. I’m just now finishing the first major system update since the 1980s. I’ve gone back to serious analog, recently adding a Pro-ject RM10 with Sumiko Blackbird through a Pro-ject Tube Box phono pre-amp. (I’ll do a review of the RM10 baby soon, including DVD-Audio samples, but that’s in the works due to technical challenges that I’m working through). This August, the Celestion SL-6 speakers were replaced with 4 ohm, floor-standing Vienna Acoustics Beethoven Baby Grands. Most recently I replaced the Bryston with a Conrad-Johnson CA200 control amp (see review).

Back to the speaker set, my dealer is Soundings in Greenwood Village, CO, owned and operated by Rod Thomson. Rod has several decades of experience in the audio business and is a true music lover. He’s been a dealer for Sumiko for a number of years and attended a several-day course to learn their “Master Set” technique.

When you read reviews of Sumiko-distributed speakers (Vienna Acoustic, Sonus Faber, REL and Sequence) you’ll often see the reviewer mention that someone from Sumiko came out to optimally place the speakers within their listening space. Michael Fremer mention it in this review http://stereophile.com/floorloudspeakers/506vienna/ The reviewer almost invariably will say something about how close the optimal placement was to what he would have used. Please remember that that comment is an ego thing, since it’s of interest to a reviewer to let the readers know that he knew all along how to set speakers.

Well, I’m humble enough to realize that I needed help. While my Baby Grands were breaking in I spent an hour or so every weekend moving them around, searching for a totally cohesive sound. Every other week I was tempted to move them back toward their rear wall, but every time I did it, I screwed up the all-important midrange. Not that the bass was always smooth. I’d get it sounding really good with “Ballad of the Runaway Horse” (same recording that Sumiko uses) but then I’d put on an orchestral piece and certain bass notes would pop out and overwhelm the music.

Still, the midrange was the most problematic to me. It seemed like when I got a really nice, deep, full bass that the mids would get congested and thick. Female voices would lose some of their character and the sound would seem to be thrown at me and be more piercing than I could enjoy. I found myself turning down the volume. Since I value accurate voice, accurate brass and imaging more than anything, I’d ultimately give up on the bass and move the speakers into the room until the bass stopped smearing things.

My self-derived set was actually very satisfying. Vocals were very coherent, full of nuanced timbre and the imaging had lots of depth and side-to-side accuracy. The Baby Grands had way more bass than my, now retired, Celestion SL6s, so I was pretty darn happy. Anyway, after I had a couple of hundred hours on the VAs it was time to call Rod for my Master Set. Generally, Sumiko dealers offer the set as part of the speaker purchase; however, as I understand it, not all dealers have the training. We’re lucky in Colorado, since Rod has the training and several years of hands-on experience implementing the technique.

By the way, skeptics are welcome. Rod told me he was a skeptic when Sumiko first came to his shop to show him. After decades in the business, he didn’t think there wasn’t anything he hadn’t seen or heard, yet he was floored by the impact. He does the set up for non-Sumiko customers for a fee. He told me of recently setting a pair of B&W 801 for a skeptic and the guy is now bringing in buddies from out of state to hear how amazing his system now sounds.

The process took about an hour and a half in my large room. Rod came in and longingly eyed the long wall with the fire place facing the Rocky Mountains. He said something like, “you could move this, move that and I guarantee you’ll be amazed with what your speakers do, OR I can put them along where you have them and get something less.” I thought about it. The WAF of the long wall was low, not because it wasn’t a good idea, but it wasn’t her idea. I thought, if I try my set up and fail, I’ll have to pay next time, but, what the hey, it’s only money. So I asked Rod to do his best with the placement that I preferred.

In a room that’s roughly 16’ X 40’ I was asking him to set the speakers on a 7’ wall, with a hall on one side and large, odd shaped entry on the other and a 40” armoire in the middle. The ceiling is 10’, BTW. The building is concrete, high rise construction with 10” slab floor and ceiling.

Anyway, Rod accepted the challenge and “The Ballad of the Runaway Horse” soon filled the room. I could attempt to reveal the whole process, but that would be futile. I witnessed the whole thing, start to finish, and actually helped a time or two and I couldn’t replicate it in a new speaker positions. I will say that he started with the bass, beginning with the speakers just a couple of inches from the rear wall and then moving them out an back while listening to the nodes. He worked the left speaker first, and then the right, focusing on getting the bass balanced between the two speakers, but with no nasty nodes in the midrange. Toe-in and rake angle were critical to the midrange and balance, but I think that getting the bass right and avoiding the midrange nodes was the single most important factors. Still, it’s a comprehensive system that you’re not going to be able to read about and then do. Listening and hearing the nodes takes some training. I was amazed to hear MAJOR changes with just ¼” of movement.

Bottom line, speaker placement is very sensitive to distance to the wall, speaker distance from each other and surrounding walls, speaker rake, speaker plumb (levelness) and toe-in. In certain circumstances the smallest movement can destroy the whole thing. On the right side of my setup there’s a wall angle that juts out at about a 45-degree angle. The smallest movement around that can screw up my set up.

Here’s one phenomenon that amazed me, the apparent volume of the system is about 1/3 lower. It’s not because the system has less sound energy, but because the harshness and phase anomalies are removed and it’s pleasant to listen at much higher levels. My C-J CA200 has a step-attenuator with 99 steps of .7 dB. I’ve never listened at 90 before yesterday. Stuff I listened to at 55 before is now at 70. Right now I’m listening in the background at 40 and that’s very coherent, but it’s low because people are asleep. Rod and I were actually carrying on a conversation as I had something on at 70 on the CA200’s LEDs.

The bass that I gained is mind boggling. I’ve listening to orchestral stuff and string bass stuff and I’m just blown away by the extension and clarity of the bass. My VAs ended up about a foot out from the wall, with about 3” of toe-in and 56” between the front toes. The image covers the whole wall. When I go into another room, the sound stays coherent and is actually louder at lower levels than before. Yes, a paradox. Up close, it sounds softer at a given level, but that sound travels further through the apartment. I suspect it’s because all inter-speaker cancellation has been eliminated, or at least minimized.

Now for the BIG PAYOFF, the mids are better than ever. I hear every little thing, in balance. My daughter put on a Brazilian CD that must have had 16 percussion instruments going, along with vocals and guitar. She couldn’t believe how much more she was hearing. I was hearing it for the first time and asked, “what’s that thing that sounds like a cross between a dulcimer, guitar and drum?” She’d seen a DVD of the group and said, “It’s something that looks like a cross between a dulcimer, guitar and drum.” The Brazilians apparently haven’t stopped making new instruments. Anyway, this recording was very dense, but with instruments spread all over the place. I “got it” 8 measures in.

This set up make light work of sparse studio recordings, like you might hear with Nora Jones. You hear each smack of her lovely lips, her Texas twang and incredible instrumental sounds. I loved the snare on one song, with the drum head a little lose and the snares a little tight. Wow, it sounded like one of my buddies playing snare at the end of my room. The voices in harmony separate into their individual pieces, yet you also hear the blend of the multiple voices.

Vinyl still sounds better than average digital, but I’m finding myself listening to more CDs on my poor little Oppo HD981. I think the removal of the distortions caused by the speakers made the digital distortions much more palatable. The midrange just falls effortlessly out of the speakers now. There’s no edge, beaming or other distractions (refractions?).

How do I measure this improvement? It was at least as good as going from the Celestions to the Baby Grands. Now I’ve got the bass extension of ported, three-way speakers combined with the imaging of sealed mini-monitors up on three-foot stands, pulled into the room. I’ve heard much larger speakers that don’t have the bass extension that I now have. It’s like I doubled the size of my speakers. I mentioned that the image covers the wall where the speakers are placed. The depth that I had with the speakers pulled out is still there and rock-steady.

What will it cost you if you don’t own Sumiko distributed speakers bought from a trained Master Set dealer. I don’t know. Sumiko doesn’t even mention it on their site. It’s better than if I’d spent thousands of dollars on equipment. It takes a couple of hours. I’ve paid lawyers with much less skill and training $250 an hour, so I wouldn’t flinch to pay $500 if I moved to another home and needed Rod’s help again. Think of this as another component purchase. Would you pay $500 for a good phono pre-amp? If yes, then this’ll give you several orders of magnitude more in system improvement.

DC,

I did some needed tweaking (manual and by ear only) of speaker location with my Ohm 5's today and had a similar result regarding playback level when done.

You know of what you speak!

It's amazing how few people "get it." Welcome to the club. Cheapest upgrade you ever made, right?

Yes. I'm back to where I was after my recent upgrades and before the Ohms were moved.

It's helpful having another set of accurate speaks like the Dynaudios in another room. Having multiple speaks in multiple rooms for reference helps me maintain better results in each with less guesswork.

My Mahlers were professionally set up by Rod Tomson of Soundings. . . and the resulting enhancement was nothing short of bleedin' remarkable! And the funny thing is that all he used as measuring instruments were our collective ears and a simple leveller gage to make the Mahlers perfectly horizontal after mounting their spikes.. . . welcome to the club Mapman!

This protocol was presented by John Hunter the owner of Sumiko. They are USA distributors for SME, Sumiko, Sonus Faber, Vienna Acoustics, REL and others. This is the best room set up tool I have ever used.
The most critical part is getting the speaker rake angle adjusted after you have them finally situated. So I hope your speakers have spikes. You will need them to set the rake angle.
If you have no spikes, you can get door shims at Home Depot or Lowes. These are wedges are used to hang the door frames to the studs surrounding the doors. There will be people to help you find these shims. They are inexpensive and you can use them to figure the angle you need, and then find something more in tune with your decore to provide the final angle.
So here is the Iron Chef Speaker Set Up Protocol
Proper speaker set up requires music. John Hunter of Sumiko uses a Rob Wasserman song featuring Jennifer Warnes called "Ballad of the Runaway Horse". You will find this on his “Duets” cd and his “Trio” CD as well. This is the best set up song I have ever found. So get a copy of this. You will always be glad you did. Another tool I like to use for fine tuning the speakers is Bob Chesky's Jazz Sampler Number 1. Cuts 10 and above really help you nail it down solid.

Step 1 will be to remove whatever removable sound absorbers you have. Take them out of the room. Anything that is permanently fixed and all your furniture and stuff are ok to leave alone.

Step 2 recommends you either remove the speaker stand spikes to make moving the speakers easier, or at least level all the spikes so the speaker is completely level. If you own heavy speakers you are probably better off adjusting the speakers with the spikes in place and set level.

Step 3 is to establish your listening seat. Optimally you will set up the speakers and your listening seat in the shape of an triangle. I like my speakers at least 8-12 ft apart and the listening seat 12-15 ft back. When properly set up, the speaker will be out at least 18” from the rear boundary wall. Your listening seat likewise should be at least 24 inches from a back boundary.

Step 4 places both left and right speakers directly against their wall facing straight out into the room. No inward “toe in” angle should be attempted yet.
The left speaker is going to become the anchor for the set up.

Step 5 gets you grooving. Now you can begin playing the “Ballad”. What makes this song so effective for set up is that the plucked string bass is at realistic volume at realistic timber. So the goal is to get the bass properly coupled to the room and the drivers.
Play this track at volumes where you can easily detect bass quality. I am usually between 80-95 db when I do a set up. Sometimes you will need to crank it up a bit. Just make sure it is loud enough to fully engage the room.

Step 6 involves a buddy. Have your buddy slide your left speaker (the anchor) out into the room until the bass becomes solid and authoritative. Mark this spot with some masking tape.
Now slide the speaker right and left to find the best bass quality. Mark this spot.
Now slide the speaker further out in the room to find other points where the bass couples properly in your room. There are likely to be a dozen spots within a 3 ft diameter of your first spot. Be patient. 1/3 of an inch is all that differentiates a good bass quality from a lifeless bass sound.
Listen to all of these good bass points until you find your favorite bass spot.
All this is done with just the left speaker playing straight out. The right speaker is playing straight into the room from the back wall. Each speaker playing at the same volume.

Step 7 establishes the “toe in” angle of your left speaker toward your listening seat. You want the widest possible sound stage without the sound being too thin. I usually end up seeing about 2/3 of the inside wall of the speaker when I have this about right. Do not toe in excessively, you will just ruin your sound stage. A little dab will do you! If the toe in is right, the sound will be very natural, if it is too wide the sound will be thin, and with too much the sound will seem to come from two speakers not from the space in between.
Your anchor is now set. Mark this spot carefully with masking tape.

Step 8 requires reinsertion of the left speaker's spikes leaving the speaker level at this time.

Step 9 is to set up the right speaker position. Simply slide or move the right speaker out into the room. Move it slowly listening for the sound stage to line up equally before you. By this I mean a stage is flat in front of you. The sound stage should not sound tilted, like one speaker sounding closer to you than the other. Remember to keep the speaker oriented directly straight ahead. No angle yet.

Step 10 involves moving the speaker right and left until you hear the soundstage become cohesive, and Jennifer should sound like she is right dab in the middle.

Step 11 Then toe in the angle the speaker very slighly until you hear Jennifer Warnes voice become a “body” centered in the sound field. You will hear the sound congeal nicely at this time. Things are really beginning to sound better now.
You should now have accomplished sound coupling of the speakers to your room boundaries. To test if this is the case, you should be able to stand directly over either speaker and clearly hear the other speaker.
It may be necessary to make very minor angle adjustments of the right speaker to get her voice centered. Be patient and you will be rewarded.
Now if the sound stage is not linear, meaning one speaker sounds more forward than the other, then simply slide that right speaker front or back until the sound field is "level." (Moving it right or left adjusts the centering of Jennifer Warnes voice).
Make sure you mark the final location of both speakers with masking tape.
Insert the right speaker spikes.

Step 12 begins with adjustments to the rake angle of the left speaker. You accomplish this by adjusting the spikes to get the speaker level across the front, and raked back to get the beam of the tweeter firing above your ears. You need to listen to the quality of Jennifer Warnes voice. She should appear to be ear level or slightly above ear level in the sound field. This is a personal choice. Many of my friends prefer ear level because it is a slightly fuller sound. I prefer a little above ear level cause I like the voice to sound ultra natural, like a live musical event.
Carefully listen to the tweeter response of the left speaker and make sure that the "beam" is at least an inch or two above your ear when you are seated in your listening seat.

Step 13 begins by adjusting the spikes on your right speaker to match the "height" of the left speaker.
At this time, you should hear her voice almost as a whisper, when originally it may have sounded shrill and harsh. Her voice should be centered in the sound field now, with solid and good quality bass.

Step 14 suggests you take measurements of the speaker location to the walls. Take digital photos. Someone will mess with your set up some time. You need to have these so you don't have to repeat the process unnecessarily. When you have this locked in, don't let anybody touch your set up!
I like to follow up the set-up with some confirmation tests. I prefer the Bob Chesky Jazz Sampler 1 CD. On cut 10 the speaker starts out 2 ft from the microphone in center stage. Then he moves midway right, full right, and off-stage right. He then repeats this on the left. Simply slide your right speaker right or left to get the sound staging perfect. Then use cut 11 which is “Over”, “Lateral”, “Under” and “Up” to verify your rake angles.
Your friends will be amazed. Just two CD’s let you make the magic. Rob Wasserman’s Duo or Trio CD, and Bob Chesky’s Jazz Sampler 1.

Step 15 bring back any sound absorbers and reflectors to see if you can improve upon the sound. But don't touch the speaker’s location.
What you have done, in short, is to couple the speaker's response to your room based upon your listening seat.
This process will take me 20-30 minutes or longer. On your first dozen set ups it may take longer.
Let me know if you have any questions about this process. I can do this all alone. Having a buddy slide your speaker is much faster and easier. If you have hard floors instead of carpet, you can set the speaker on a soft towel to assist in the sliding.
Make sure your buddy stands behind the speaker when he/she moves it, because their body will affect the sound if they stand along side of the speaker.
