SW-800 Subs & CLS's

After much searching I have a line on a mint pair of Kinergetics SW-800 Reference sub-woofers (twin towers with 5 ten inch long throw drivers on each side). These were specifically designed for my Martin Logan CLS's -- a mini Statement in its day. These are the second generation with a single crossover device (the originals had dual 300 watt monoblocks/crossovers). Does anyone out there have any experience with these? Concerns... the speakers are virtually un-used, but they were designed with SEAS paper woofers (less mass to move quickly with the CLS's). Do these deteriorate even though un-used and in the original packaging (we're talking 5 or 6 years old)? Also, the reviews stated that these subs will ruthlessly reveal the quality of the amps driving them (unusual for subs). Unfortunately, the only spare amp I have these days is an old Adcom GFA555. Any recommendations? Should I stick with the obvious choice of solid state? If so, what? I'm using tubes for the CLS's with great results. Lastly, the subs have a nominal impedance of 1.6 ohms -- great match for the CLS ;-). Thanks in advance.

gfa-555 should work yust fine w/those subs - bass response is a strong-suit of these amps. i use a pair of 'em bridged, to drive my vmps subs. at the very least, you could ry 'em, & if yure not happy, get something else.

sorry i can't help ya w/the kinergetics, other than i've heard these are excellent subs, & i've never heard of any cone deterioration problems w/em...

hi mig, i never said anything in my post about using the adcoms to drive loads like the martin-logans, but when the gfa555 1st came out, a hi-end retailer in my area was amazed that they could drive the notoriously difficult apogee scintillas, that would destroy *better* amps. anyway, all i said here is i tink adcom amps wood be fine for driving the kinergetics sub, & i still do...

regards, doug

ps - jim, as ewe know, i came *wery* close to purchasing a pair of cls, but dint, mainly cuz even martin-logan said i woodn't be happy w/their 93db max output, even when crossed-over to subs, in my large listening room. i tink the cls' are the greatest thing going for small-scale music, but there are times i want to *crank* it... ;~) thus, i'm saving for the newforms... dunno anything about the kinergetics' x-over, but i *do* know the marchand is wery flexible & wery transparent - i tink it wood be a great match for the cls'.
