I stumbled upon a pair of Carver Amazing Silver Speakers for sale locally - but because these speakers have been out of production for about 10 years - the info. / specs. on these are very brief & sketchy at best. Can anyone shed some light on these speakers? How do these speakers perform? What are they like as Front Mains in a 5.1 HT setup? What about the relability of the 48" ribbons? How's the base / midrange / highs? etc......................... Any feedback / info. / opinions would be greatly appreciated.
