Vandersteen 2w or 2wq's


I have a nice pair of Vandersteen 3a sigs and was thinking about adding subwoofers.
Audiogon has listings for a pair of 2w's. My question is:
What differences are there between the 2w and 2wq's(besides the variable q) sound wise?
Should I be concerned about buying an old subwoofer-does anything wear out and need replacing?
Thanks Bob

As you mentioned having a smaller listening room (your post about a telecon with RV) I suggest spending lots of time/effort properly  positioning the 3A Sigs for best overall balance and leave it @ that.

Even in a large room the V subs rarely come into play, when mated with the 3A and/or 3A Sigs, with most music.

I also spent an afternoon auditioning the original 5's, when they first came out, and felt that the above held up as well (for that model as compared to the 3A Sigs + V subs).






Delkay, this is my 1st post.
I have no idea what a telecon is..., but thanks for the information.

I have to agree with you though, when I move the speakers around, I do hear difference.  My problem is that I have a limited number of places to move the speakers. That is why I thought using subwoofers would help, though I might be mistaken.
the 3a sig which i owned for a decade put out significant and high quality bass...tuning to room involves some work but so does any speaker..the manual is a great place to start. Do you have a Vandy dealer nearby ?
you might also invest in an analog Radio Shack SPL meter and download the Vandertones. You dont have the Quattro EQ but you can tune via movement. Use your ears also.
i dont think RV spends too much time here, thank him on the Vandy FB page..he might see that. 
you also have Rutan commenting on your thread he is IMO top 3 Vandy dealer in USA.

GDNRBOB:

Telecon (also telcon) is 80's speak for telephone conversation (in this case the one you mentioned having with Richard Vandersteen).

A few inches (one way or the other) can make sizable differences in the bass/mid-bass qualityof a speaker, which is why I mention "time/effort" in my post.

Anyway, just saying do the best you can with what you have before adding subs/moving on et cetera.
