It has been quite a while since I visited here. The purpose of this post is to once again suggest that you evaluate your source preference when trying to decide if subs will benefit your system. Paul and I debated this quite awhile back. Paul likes subs without reservation. He also listens mostly to classical music and prefers digital sources if memory serves. While I have those things, I am more of a vinyl guy and listen to a lot of old jazz recordings made from the 1920s, 30s, 40s, 50s and 60s. Not a lot of bass in my preferred sources. With that as back ground, I recently bought a pair of REL 212/SX speakers. Paul is right that they add a tremendous sense of depth, impact and excitement if the source material has signal below say 40-50 cps. As you might guess, however, my old jazz recordings do not excite my new REL speakers at all. As in nothing coming out, nada. Which, in all fairness is exactly what I expected. Am I happy with the RELs? Yes, but I went into this with realistic expectations. Nobody seems to discuss this important factor in the decision process.
