Best subwoofer to complement my system.

Can't give you an A/B comparison, but just researched this topic and bought a Velodyne DD18 that I have not yet hooked up.

Any article/review that I found written since the DD's have been avaiable have included them as a serious player and some folks on here have integrated them with some very highly respected speakers.

Jazzy123,

First off, let me say that I have not had the greatest experience trying to integrate subs into 2 and 3 way full range speakers for the purposes of critical music listening.

Back when I had Wilson Watt/Puppy 7's I had two Wilson Watchdog subwoofers in my room and even though it was all Wilson there was a lack of seamlessness which I always heard. And I have a purpose built treated and calibrated listening room and the locations for my speakers and subs was carefully computed to be optimal.

Then when I switched to my Dynaudio Temptation speakers the integration challenge worsened because the Tempts are much faster and resolute down low to about 35-40 Hz. Whatever I gained in the lower octave with the subs in, was taken away by having to put up with less resolution. Anyway, I gave up and now just listen to my Tempts without subs.

I do not mean to discourage you! Just sharing one man's experience. I did switch to Rel subwoofers and I do believe they integrate better than the Wilson Watchdogs so the Rel is certainly a sub that should be on your short list.

Good listening.

I recommend Martin Logan Descent sub. This sub is very fast with deep controlled bass. I use one with my Summit's.

I'd have to agree with Earflappin.

Sub integration for music is not that easy...and very room/speaker placement dependent. Why?...because of all those reflected and standing LF waves from three sources: two speakers and a woofer.

I went for a corner placement for my sub (along the speaker wall and aligned with the speaker baffle edge). This keeps the phase alignment with the speakers and I suspect only works because I have few room resonance problems (large odd shape room and no obvious related multiples in dimensions).

I still needed to use a notch filter in the DSP for the 40Hz mode which was about 6 db too strong but there are no major suckouts with my corner position. I got major suckouts (up to 15 db) when I tried other sub room positions.

In summary, adding the last lower octave may bring a host of problems with it [unless you are willing to renovate or go for extensive acoustic treatments].
