I can't speak for the Coincidents, but I do own Silverline Sonata II's. Mine are approx. 20" off of the back wall, and have no problems with booming bass. Most speakers will benefit from being off the back wall a bit. Both speakers have a good reputation... you probably can't go wrong.
Your Opinion: Coincident Vs. Silverline?
Hi, I'd appreciate your opinions on Coincident speakers and Silverline speakers in general for a system I'm putting together. I listen mostly to jazz and rock at moderate volume levels and what I appreciate is a transparent, detailed, musical presentation. My budget is flexible, the only stipulation is the speakers would need to be fairly close (12" max) to the rear wall and my listening room has furniture and all maner of things in a normal living room. Thanks!
