Mcintosh XR-14 Isoplanar Speakers Plz Read. These work and kick much a**!! The cabinets are a little rough, and the main speakers will need foam edges replaced, they are starting to deteriorate. But even with the small tears, these speakers hit hard! Were hooked to vintage Onkyo reciever and very impressive! If interested in speakers and components only, I am willing to strip them and sell that way. The cabinets all together are very heavy and will be very expensive to ship
