Why a second Vandersteen sub?

I've been enjoying my Vandersteen 2WQ sub that I'm now using with my Vandersteen 3A sig speakers. In fact, I think that the effect of the sub with the crossover is dramatic with a greatly improved sound in the midrange as well as in the bass. I know that Vandersteen and several people at this site recommend a second 2WQ sub, but my question is "why?" What will the second one give me that I don't already have with one? Is it just the location of the deep bass?

Bigtee is correct. Also, make sure you are using the fixed filters. Several folks here make them, using better caps than RV, for lower cost. But at least, go the X-2s.

If you are using it with a 2-channel system it will improve
on the location and imaging. In my Linn system (2-channel)
I first used one AV-5150, ran L & R cables to it so that the internal circuit will blend both channels. Even at the
lowest setting on the sub's crossover (40 hz) you could feel the bass moving towards the side of the room where the sub was placed. In my listening room placing the sub between the L & R speakers was not an option. I got another
AV-5150, place each one in the rear corners and love the way they sound. You will find an excellent explanation on why two subs are needed in a 2-channel system in Robert Harley book, "The Complete guide to High-End audio".
Only one sub is used in Home Theater systems because the .1 channel of the 5.1 channels is a dedicated low effect mono channel. On some HT systems two subs or more are used to compensate for the room size. Hope this will hepl. Hector

Swampwalker, can you identify the members who make the improved filters? I've been thinking about doing it myself, but never seem to have time. Would be good to know who to go to. Thanks in advance!
