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,

Thanks for all the responses. After reading my comments again, I admit it does sound like a sales pitch (and I hate that kind of G@Bs hype!). I was just so taken in by this sub though; I guess the conditions were "right" and I got a little gushy. I don't take back anything said though; its just my own perceptions anyway.

Thanks, Audiofreakgeek for the insights on Earthquake and JL Audio subs. They have their rightful places for good reasons. I remember the naturalness and tonality of the JL was without peer. As I mentioned before, I look forward to reading about a direct comparison with the DD Plus series, if anyone can swing that.

Don't forget that the new DD Plus series is a different animal altogether than its predecessors; totally different magnet (much larger), cabinet, cone, electronics.

Lewhite: Two subs will beat one any day as Dave agrees. I'd get another one but the wife would roll it out to the curb with me stuck in it!

Dgarretson: It looked to be around 35 or 37 hz roll off but I'll have to double check.

Good points about servos vs non servos. JL may still be the harder hitting as Davehrab mentioned. When set to 200hz crossover, the DD15 Plus seems to impart a kind of organic weight to the individual instruments in the presentation and does it in a crispy, unclouded way. But then again, JL can do this as well, perhaps with even more finesse. I wish I could have one of each to compare.

Not trying to pitch anything here, just sharing the discovery of a new thing and asking for more insights from those more experienced. Thanks again for all your thoughts.
Even the DD15 - the original - is a great sub.

Very musical and easy to blend with your main speakers. It has been the best sub I have owned.

Enjoy(
Audiofreakgeek sells both earthquake and JL so take his comments with a grain of salt.

And his calling the op's comments a "marketing pitch" is the ultimate in hypocrisy.

LOL
Yes, REL is another amazing sub. Are they still made in the same factory or have they moved onto China? If so, I question the materials and quality.

An A/B comparison between the original DD and the DD Plus series would be very interesting.
