Best Subwoofer avaible?

I have a pair of the new powered 21" Cabasse A55 subwoofers on order for delivery in late march or early April. Based on what I heard at CES, I think they may be state of the art. They incorporate a woofer whose mass is about that of a typical 10" driver, a 1000 watt amp, a parametric equalizer, variable phase and cross over point and weigh 450# per side.

I too have tried REL subs (as well as many others)- and I could not get them integrated - in fact, they sounded the best when they were unplugged. If you ask Wilson Benesch about subwoofers, they will most likely tell you what they told me, "Subwoofers are evil". I didn't believe it at first but I do now. One of the many benefits to using Wilson Benesch speakers is how seamless they sound - adding a subwoofer seems to introduce nothing but problems.

If you go with a sub, make it a Velodyne HGS - 12" or smaller and try to find a home for it in-between your speakers or the midrange & soundstage will get too distorted. The volume will need to be set very low and the crossover must be set to the minimum (40Hz) or use an external crossover set between 33 and 37Hz depending on your room for better integration.

The Revel B15 driver (made by JBL) is available by itself - so, buy it, build a box, and equal or surpass the B15 performance for 1/4 the price or less. I think P.E. has the driver....

the Tumult is a good choice too, DIYcable.com I think has kits using that driver and a plate amp - for around $800 or so? build your own box or buy theirs...

I just picked up a Velodyne DD-12, and let me say that this was the most significant upgrade that I have done to my system. I have a very difficult room, bass-wise, and the ability of the Digital Drive series subs to not only analyze, but also correct for, such room characteristics is nothing short of revolutionary. Combine that with a very fast, musical sub that absolutely disappears, and it becomes a tough act to beat. Don't shy away from Velodyne just because they also make more affordable subs. The Digital Drive line is very much a "must audition" line of subs.
