For your consideration is the amazing JL 113. Tremendous power with room EQ. Comes complete with microphone and accessories. Single owner trade in used in an ultra high end system. Gently utilized.
Stereophile: I recommend the JL Audio Fathom f113 for Class A of Stereophile's "Recommended Components," and urge you to listen to a pair of them. I'm sure you'll be convinced, as I was, that the benefits to your system's soundstaging will be as impressive as they will be in the reproduction of deep bass. My entire system achieved its best performance to date, producing clean, tight, solid bass signals with excellent pitch definition. Great work, JL Audio!
