I notice that Kurt uses a subwoofer with his jr's, something that I have thought about doing.
Here's my situation. The actual "listening room" is a small area (11' x 12') but it is acoustically open to the rest of the ground floor -- Victorian house with pocket doors on two walls that are normally left open. Using my old Stereophile test CD, I find that the bass output is reduced below about 125 Hz and really down below 63 Hz. Because of the open environment, I don't have problems with standing waves (good) but neither do I get much reinforcement from wall boundaries -- a little off the back, I think -- which may explain the results from the test CD. My amp is 250 w/ch and I never run the system higher than 50% volume on the preamp, so I don't think the problem is lack of amplifier power.
What I hear is confusing. Some recordings sound just fine -- I can hear the bass lines clearly. With most classical and some pop music, sometimes I don't get enough bass so parts of the bass line aren't audible, which makes sense given the test results. But with some pop music, very rarely classical, I get too much boomy bass; perhaps because of compressed recordings? Last night I had a pipe organ recording on, with plenty of room-vibrating bass, but with well-defined pitch. Where did that come from, since I know that the jr's output is way down at the bottom end?
So what would adding a subwoofer do? If properly adjusted, would it fill in the missing bass lines without exacerbating the problems on some pop recordings? I'd be interested in any comments, particularly from VR-IVjr owners. My listening is mainly classical and folk/acoustic/americana stuff, less often pop/rock and jazz.
