IMHO a subwoofer is the last thing I would want to bother with and like the 3A idea, which sogood51 mentions would have the better midrange too.
Add subwoofer to current speakers or upgrade?
I am considering upgrading my speaker system. Currently I have Vandersteen 1B's powered by Classe' CAP-151. I have looked at adding one REL Storm subwoofer to the 1B's or upgrading to the Vandersteen 3A's. I don't think at this time I can go with the Signatures, although I'd like to. The stereo is setup in the basement which is fairly large. I would appreciate any suggestions on this. Thanks in advance for your thoughts. Happy listening!
