subwoofers: the bigger the better?


Hi guys, I wonder if a bigger subwoofer would blend in a more satisfying way with the sound of your main speakers. I own a pair of Dunlavy SC-IV's and I'm considering to add a REL subwoofer to the system. I can buy the Stentor III, but maybe the Studio III would sound better in combination with the Dunlavies. The folks at REL say that one Studio subwoofer is better than two Stentor's. I once red that the lower the main speakers go the better the subwoofer will blend with the sound. I also heard during a high end demonstration 8 years ago a pair of Wilson WATT 3/2 with a Pow Wow subwoofer (the size of a large coffee table) driven by Krell KAS amplifiers (+ Audio Research LS-2 linestage), and the sound was the most impressive I've ever heard.

I also agree with stereo subs. Added a 2nd Vandersteen 2wq about a year after the 1st. Improvement all the way around...
Bigger is better, if only because the more cone area you have, the less cone excursion is necessary for a particular SPL. Of course there are the spatial issues which others have mentioned. My three front speakers have six SW drivers backing them up, so the LF response is not only there, but has an effortless quality, not usually experienced with the typical long-excursion hard-working powered SW.
At the Las Vegas T.H.E. SHOW 2004 I was taken into a back room and shown a prototype subwoofer that is going to change our ideas of low frequency reproduction for a long time. Think of it, a subwoofer the size of two cigarette packs that can reproduce 40hz. The retail products were slightly larger than 2 shoe boxes and could 25hz with ease; and it is all done through resonance matching and original thinking.

I agree. I listened to the top-of-the-line TBI commercial offering, an 8" subwoofer that combines bass reflex and transmission line concepts. It was fast and tonally balanced, and integrated well with the main speakers. I think it is the best sub I have ever heard, and purchased two to accompany my Quad 988's (fast enough subs are very difficult to find for the quads). It is very reasonably priced compared to the REL line. I sold my ACI Titan LE sub, which I also like better than the REL's (less boomy).
A good part of it is how loud you want to play, my Nelson Reed 1204s will supposedly do 120 dB at 1 meter but my ears won't. Each has 4 12s and will play cannon shots my older Hsu's won't but the latter work fine on music and are more practical. I would go with stereo also, although opinions differ on this. I like the REL system of using the amp output as signal. I can't do this with the electronic crossovers I use so I run my main speakers full range and keep the signal to them out of the crossover by using Y plugs.
