Review: Acapella Triolons Speaker


Category: Speakers

I currently own the Acapella Campanile Highs and have used them as a reference for about three years and hear Acapella Violins weekly at a friend's home. The remainder of the equipment and speakers were auditioned over a 30 hour, 3 day listening session. All amps mentioned and all equipment listed were listened to on the Triolons, carefully varying one component at a time with the Triolons remaining the one constant during the 3 days. The other speakers listed with the exception of the Campaniles and Violons were auditioned during the same weekend with the same equipment but for much shorter periods. The Coltrane Supremes were breaking in; the Coltranes were fully broken in.

The Triolons are an imposing sight. Two woofer towers, each 14" by 28" by 7' tall, each weighing 650# plus a cross piece holding a plasma tweeter attached to the woofers and a sword bearing two horn loaded speakers, one horn 30.5" in diameter, the other 18.5" in diameter. The Triolons can be driven by a single amps of 18 watts or higher power but must be triwired and have an efficiency of 97 db. Each side weighs 850# total. The crossover points are 200, 700 and 5000 hz.

The sound from 200 hz up to 40,000 hz emanates as a spherical wavefront. The Campanile Highs are similar but crossover to their woofers at 500 hz, use the plasma tweeter plus a single horn and are much lower in efficiency (92 db). The Triolons are typically a 6 ohm speaker but have an impedance at 30 hz of 28 ohms. The same is true of the Campaniles. Neither is a particularly easy load for an amp to drive; however the greater efficiency of the Triolons does open up the possibility of driving them with the right low power amplifier.

In my experience it takes a high power, high current, low output impedance amp to make the Campaniles come alive, with the exception of the Einstein OTL's which are used at the Acapella factory and do an admirable job of driving both speakers. The Triolons are much easier to drive than the Campaniles, but also more revealing of the associated equipment used to drive them. Different combinations of equipment resulted in different tradeoffs. Generally, the more expensive set ups involved fewer tradeoffs.

Another Audiogon poster has developed a nomenclature characterizing various pieces of equipment using the terms "workhorse", "realistic", and "magical", with magical suggesting that the system does some things so well that it results in a suspension of reality - you are no longer listening to reproduced sound in your room, but are somehow transported to the event. I have a bad tendency to think/listen in terms of how well a system does certain things and how well it avoids doing things which irritate me, which is to say that I have a bad tendency to focus on the pieces rather than the whole. In those rare instances when a system is so good that I stop analysing the sound and just listen to the music, then I know that something is right.

I am told that my initial reaction to listening to music on the Triolons was to stop talking and get a silly grin on my face. I don't know about the goofy grin but I do know that I did not say a word until the piece of music ended. If you know me, that says alot. I have now lived with the Campanile Highs for a number of years and they are by a significant margin the best speaker that I have ever owned. They are a difficult speaker to make work properly. They require a large room and are hard to drive. Amps that drive the woofers well do not ever seem to work as well on the midrange horn and plasma tweeters. The happy medium is either the best solid state amp which you can find or an OTL with at least 60 real watts of power (read the Einstein). The two types of amps sound different on the Campaniles and have different strengths and weaknesses.

The prime goal of the Acapella design team on the Campaniles was to get the best match between the woofers and the midrange horn and not the most extended bass response (the Campaniles are reasonably flat down to about 40 hz but drop off rapidly after that).

All of this is a prelude to talking about the sound of the Triolons. What makes the Triolons special? In many systems the soundstage is either localized between the inside edges of the speakers or perhaps extends to the outside edges of the speakers. With the Campaniles and the right equipment you can get a soundstage that extends from wall to wall and has excellent depth. Focus and image specificity are good but never pinpoint. Image size is believable, i.e. no sopranos with mouths the size of a baby grand. If the Campaniles have a problem in this area, it is that without proper set up and the right equipment some frequencies can localize on the horns. This is most problematic during the time when the speakers are breaking in but can happen with the wrong wire or associated equipment and is set up dependent.

The Triolons create a massive soundstage with huge amounts of air and space. The sidewalls of the room from the plane of the speakers and the back wall disappear. Instead of recreating the recorded venue in your room, the room no longer seems part of the equation. Its almost as if the space where the event occurred is appended to the end of your room and the recorded event is occurring there ( note that this is only true with certain recordings made in large halls and properly recorded and not with every piece of music played or with all associated equipment or wire). Imaging and focus are quite good but edges are a bit diffuse as in real life. Images are very three dimensional and fully fleshed out

A friend is driving Watt/Puppy 6's with MacIntosh 501's. This combination has great punch in the midabss. My Campaniles with my equipment never had this degree of punch in the midbass. With the Triolons this is no longer the case. Their midbass is extremely detailed, fast and well controlled with excellent slam.

The Campaniles will play loud and are very dynamic from pp to fff. The same is true of the Triolons but much more so. The Triolons significantly extend the dynamic envelope with excellent microdynamics and crescendo's capable of rattling walls, all with a vanishingly low level of distortion. Detail retrieval, particularly low level ambient detail is phenomenal. I am simply hearing low level detail that I never knew existed on familiar pieces.

The Triolons are very coherent and seamless. They have an effortlessness that is reminiscent of the Goldmund Reference TT which I owned for several years. Images have a solidity and three dimensionality. In comparison to the bass of the Campaniles, the bass of the Triolons is tighter, better controlled, goes lower with more authority and is faster with greater retention of harmonics. More importantly, by pushing the horn technology down to 200 hz and dividing the range between 200 hz and 5000 hz so that it is handled by two horns, there is a significant lowering of intermodulation distortion that effects the entire range. Acapella has been able to do this in such a manner that the two horns act almost as a single unit. You cannot pick out the crossover point and there are no discontiuities as the sound moves between the horns. Bells and other percussive instruments have a steep leading edge with a with a natural reverberrant tail. In this area, the Triolons remind me of the Colibri cartridge. Voices are a joy on this speaker, both male and female. The plasma tweeter remains the best high frequency driver that I have heard and that includes the superb diamond tweeters used in the Martens and Kharma's.

Finally, a word about amps used during auditioning. All the amps mentioned at the end of this review were excellent. For my particular tastes the Lamm ML2 at 18 watts and the Audionote Kegon at 20 watts stood out. I hope to have a pair of the Einstein 60 watt OTL's sometime this spring for comparison. Note that the Edge Reference was also excellent at significantly more power. With the Triolons, it is more the quality of the amplification than the power (although 18 to 20 watts is a minimum). Also note that the Jorma Prime cabling proved an excellent match for the speakers, although the Valhalla speaker cable was excellent. With solid state amps, particularly the Edge Sigs, a tube linestage sounded best.

My listening preferences are about 50% classical, the remainder jazz, acoustic and 60's and 70's rock. One CD that served as a reference for system changes was the soundtrack from American Beauty, particularly the first two tracks. We also played a number of Verve recordings from the 50's, rock from the 60's and 70's and quite a bit of voice.

Ultimately the enthusiasm for a product reviewed is best determined by whether or not the reviewer is significantly enough effected by the product reviewed to buy it. I am currently working on arrangements to buy the Triolons.

Can someone please explain this statement to me:

"Whereas some loudspeaker makers are producing designs with drivers that can produce sub-octave lows and ultra-frequency highs, believing such designs would be the most faithful in sonic reproduction, making even concert grand’s to sound surrealistically thunderous and earth rattling, I think such concoctions ultimately contradict with the sonics of a real piano."

He goes on to say:

"For a phenomenon worthy of the status of a major breakthrough in loudspeaker design and production implementation, the ion tweeters and the oversized horns with the attendant columns of subwoofers were not to blast the listener with decibels. Rather, seemingly releasing energy in a sonically most unreal, gentle fashion per the nature of a horn in its coupling to the air around the listening space, the Acapella TE’s were the first transducer design victorious in shedding the common characteristic of all top designs that I’ve heard: the clustering of sound."

If you play track number 6, "Flamenco Sketches (Alternate Take), of Miles Davis' Kind of Blue, remastered edition, anywhere near realistic listening levels and listening to it doesn't make you reach for your ears than the speakers/system does not possess the dynamic range required to recreate real instruments in real world spaces. As Soo described in his listening impressions, it bears to mind my own listening impressions of the A Cappella Triolons and that is that they are gentle giants which lack the balls to reproduce real world instruments in real space; most of this due to the inefficient ion tweeter. Furthermore they also appeared to lack ultimate-resolution, this may have been a result of the upstream electronics but then again the Campaniles sounded the same with a totally different front end.

I know that the use of my reference system as a measuring stick may not be fair to the system in Shanghai but at these prices there really isn't any room for error.

I welcome Ryan, a.k.a Rhyno to come to my house and put the sound of my system up against the Triolons and associated system and report on its performance here.

The cost-to-performance yield of this speaker design leaves a lot to be desired in my honest opinion and it strikes me as interesting that the owner of Triolons here seeks to substantiate his purchase through these "parables".

Keep in mind Soo's own speakers as a reference when you read his impressions of the Triolons:

It does not surprise me that he was impressed and perhaps this will recalibrate his idea of what a good system should sound like; well perhaps it appears that it already did.
For the love of Gawd, will someone please go and spend some time with Carlos269, apparently he's lonely. "Come look at what I've got, come play with me."

What does it matter if your system sounds great if the company sucks.
carlos, thank you again for the invite. but i've heard your system, and given my precious limited time on the weekend, explain to me why it should be different this time? what has changed to make it so different than before? i recall what i heard, and it was dynamically unlimited, but not a system that invites more than short listening sessions. --now, is that dynamic expression that overcomes the listener, or something else (something less benign)? i have my recollections, and it was one of too much leading edge and attack at the expense of the holistic expression of tone.

understand i'm not knocking you: you have the system you want, and i am genuinely happy for you. we should all strive to suit ourselves, and butkus for those who don't like it. i for one didn't like it, so butkus for me. no worries though, i don't like many people's systems for a variety of reasons. methinks you prefer sound that can play at realistic levels regardless of tonal imperfections of the recorded instrument, which is a tradeoff some will make, and some won't. doesn't make anyone right or wrong. this isn't an equation. there is no right answer.

this is art.

think your comments on the accapellas are not reflective of what i've heard. are they perfect? of course not. i'd prefer more slam and more holistic imaging, but that's my personal preference. regardless of what i find most appealing, there is no doubt that they're good enough.
Ryan,
My current system sounds much more refined, neutral, extended and 3-dimensional than the system that you heard three years ago. Much has changed, just look at the pictures under my system here on Audiogon and you'll soon realize that the room and equipment in it is nothing like what you recall.

I stick by my comments of the A Cappela's. You only live about 25 minutes away using beltway 8 so why not come back so that you can recalibrate what a "True" world class system based on knowledge of sound reproduction, physics, acoustics and electronics sounds like. Why not take up this perfect opportunity, specially for a "reviewer".

As far as "tonal perfection", I think that my current system will knock you on your ass when you hear it; further more my system NOW has the flexibility where it can be adjusted to your tonal preferences on the fly (how do you like them apples?).

There is no right answers correct but some are more "right" than others!
A few additional thoughts based on changes to my system in the past months and what I heard at the RMAF. About two months ago, I changed my speaker cabling from the very good Isoclean Focus and Super Focus to the Jorma No. 1, substituting a single wire run to the woofer/tweeter and a bi-wire run to the horns. As it turned out the combination of the Jorma cabling and the change from bi-wire to tri-wire resulted in a very nice improvement in the sound of the system. While there was certainly a decrease in noise and an increase in inner detail, the real improvement was a degree of coherence throughout the trequency range, an increase in liquidity and an increase in texture and timbre. I was impressed enough with the Jorma to order a pair of Prime interconnects to run between my amp and preamp.

This was followed by a trip to RMAF where I was able to hear two excellent but very different amps (FM Acoustics and Einstein OTL's) driving respectively Campanile Highs and Triolons. Likemany of you, I find certain things that I like about using a really good transistor amp on the speakers, particularly with respect to bass contol, bass slam, dynamics and top end extension, but am willing to sacrifice some of this and accept the somewhat looser (some would argue more acccurate bass)that is produced by the Einstein OTL's if that means that I get the top end and midrange of the OTL's.

Although I have not decided which direction to go, I am currently leaning toward purchasing the Einstein OTL's. I thought that it might be interesting in posting some thoughts about the sound of the Einstein mono's driving the Triolons at RMAF.

As to the sound: The amps are very clean and excellent at creating the the well defined leading edge of struck instruments that characterizes a live performance. This is particularly evident with percussion instruments and with the piana which in my experience after the human voice is the hardest instrument to recreate in a believeable manner. Massed strings are also equally good. Decay of instruments is captured in a way that is lifelike and natural. I find it rare that a piece of electronics is equally good at capturing the leading edge and also the decay of sounds. Most seem to favor one over the other.

Human voice is well served, particularly female voice. Herman Winters must have a love or opera as he always brings a treasure trove of opera recordings to shows.

Bass is very different from that produced by a large transistor amp, a little bigger and less controlled with somewhat less impact but more organic and closer to the sound of acoustic instruments in a real space. This is probably not the combination for producing synthesized bass at high volumes, but otherwise is excellent.

As I said in another post, the sound was excellent on Sunday. At least in the RMAF room (which was very large and had an acoustic tile ceiling, a bit more power would have ocassionally been nice but not if it had come at the expense of what the amp was doing in other areas.
