Velodyne DD Plus: New King of the Jungle?


I've had the new Velodyne DD15 Plus now for about a week. I've had and heard plenty of subs, always looking for that magical moment where you are immersed in the music in its fullest range, uninterrupted by separation and unwanted resonances. Subs are difficult to judge; it depends on how well their sound can be blended with the system in use. And there's always that artificiality of tone the listener is fearing to detect, so my expectations were tamed as I set the thing up. My gear is simple, some of it is not the finest in the world but performs amazingly well for what it is, and I've heard lots.

I set it up on a stool about 8 inches off the floor, with plenty of padding to isolate it from the wooden floor(I'm funny about isolating stuff from wooden floors but it seems to sound better). It was placed diagonally, near a corner of the room. I put on some Diana Krall and roughed dialed it in. I have to say that right out of the box, not broken in and not EQ'd yet, the DD15 Plus and walls of my listening room just disappeared and left me with my jaw in my drink. I was in the concert hall with her. This sub just may be in a league of its own.

About an hour later, my wife came home. I was playing some Allman Brothers and upon walking in she exclaimed, "Something's different; did you get something new?" I was dumbfounded. Luckily it was covered up and in the same place the old one was so she didn't see it. "What Do you mean?" I mumbled. Later I confessed to her about the purchase. When asked about the sound, she said that when she walked in (45 feet from the sub), the whole house had "an atmosphere" to it and she thought "there was a live band in the living room". Now that's music to my ears!

Even as it was with the factory settings, it would have been good enough. But of course I ran the auto EQ with the microphone, video connection to my TV played the tone sweep CD it came with.

With one push of a button on the remote the DD15 plus began listening to and adjusting itself. Five minutes later it had analyzed my main speaker's low frequency output and matched their cutoff to its own, set its low level output and frequency responses to the contours of my room, set its crossover parameters, phase and parametric filters. The result was a very flat response line across the range on my TV screen. The crossover points were showing up as little dips, varying no more than -3db. It started rolling off gradually around 160db. I could have gone further with fine tuning the EQ manually but didn't need to.

Back to Diana Krall. Same effect only this time, the whole experience was smoother and more seamless. I realized its not only that the DD Plus gets completely out of the way, but it has a very organic and natural * tonality *; significantly more "real" IMHO than any other sub I've heard. I played some rock, blues, jazz and samba with the same effect. We have an extremely versatile sub here.

I'm using it for music in my stereo system so I don't need that much power. This is way overkill. However, I did play a DVD (Wall-E) on the surround system with it in place and again, it made the room disappear and put me right there in the action, everything not being lifted out but rather enhanced with detail I've never heard before. I felt like this sub could take me anywhere sonically. And the kicker is that the volume was at about 25% of its 3000 watt capacity.

I'm running Harbeth Super HL5's and they're extremely fast, detailed speakers with tons of naturalness. The DD15 Plus kept up and possibly exceeded them in velocity. For fun, I set the crossover on the sub to its highest point (200hz) and adjusted the volume. The instruments timbre and tonality were filled in with more detail and their stage presence more placed. Wow! This is one fast sub, full of natural tonality, detail and can put you right there in the musical event.

I can't wait until it breaks in -

I look forward to other fellow AG'ers who have far more experience, different gear, more brains and better ears than I do to give their opinions on this amazing piece.

Cheers,

Sonicray

Thanks for the info Audiofeil!

I cross mine at 50 htz with my Soundlab A1 speakers.
BTW, I am NOT a retailer of anything and am not trying to pitch or sell anything. I'm just a regular dude with an ear for music. I've been fiddling with audio gear for about 22 years now and have heard the good, bad and the ugly. I'm rather new on Audiogon so forgive me if I wet myself and sound pitchy at times; its just enthusiasm.

Yea, 200 hz crossover setting sounds crazy but I wanted to see how it would integrate or enhance the lower midrange with music. Try this with your sub and see if it does what Podeschi described earlier.

Question: Does anyone have a preference on IC's for a subwoofer? I'm using custom silver plated; perhaps that lends to the detail.

Sonicray, you have nothing to apologize for.

However, the dishonest and unethical shilling dealer does.

Let's all hold our breath.
Its one thing for a manufacture or retailer to brag and beat their chest (Duke and Ralph do it constructivly all the time) and not hide their I.D. Its an entirely different kind of personility that derides a competing product then remains anonomus.

To the op: I currently have one DD and thinking about adding one for a stereo pair. Would you recomend selling it and getting one DD+?
Lewhite: Of course, the best way to find out would be to do an A/B comparison between the two in your own listenng room. I have never done that; I just went for the DD Plus series from talking with David Weinhart, who gave me a lot of honest information about the performance of the two and let me decide, and I went in favor of the Plus series. We could have done an A/B there, but it was October and he hadn't gotten any shipments in yet and I decided not to wait.

I guess you could get a Plus series and do an A/B, playing just one at a time (and If you do, I'm sure many of us would appreciate the results to your ears). If you still like the original DD, then return the Plus and stay with the original!

BTW everyone, I teach in a public school for a living and have equipped my classroom with the Odyssey Extreme SE, Candela pre and Dynaudio 1.3 SE speakers and a Sunfire Signature EQ sub (all at my expense of course). The kids really appreciate it. It really kicks @$$ compared to the absolute crap the school provides for sound. When administrators inquire about it, I say it "enhances the learning environment by helping the kids develop an appreciation for music"! I hope I don't start getting the upgrade bug for the classroom though; there would be no end to that.
