Vintage AAL (American Accoustic Labs) featuring 1 15inch Poly Subwoofer, 2 mids and 4 high end tweeter combo on each speaker.  These are serious speakers for those of you who like full sound audio.  The woofers work but unfortunately the soft seal around the woofers is gone.  Can run these this way however.  The speakers present nicely and would be great for a vintage or new system.  They are designed to be used on high end systems and like to be driven.
