I found the subwoofer to add more dimension and overall better sound. I use the Merlin TXM-mme bookshelfs on stands. I added the JL112 sub and very carefully tuned it, almost to the point you are uncertain if it is on or not. With tympanis and pipe organs I get the goosebumps! Also my preamp, McIntosh C2300 has selectable preamp outputs. With the press of a button I can have the sub in or out of the system. For the most part the sub is always playing. A vote for the subwoofer providing it is carefully adjusted, placed and matched.
does a subwoofer kill stereo sound?
I was wondering whether adding a subwoofer to a pure stereo system would cause any harm to the soundstage and other features of the system. What are your experiences? Should one buy a subwoofer to complement a great bookshelf pair (that may be lacking some bass) or necessarily one would have to buy a new par of speakers with deeper bass?
