I have 6 MCM 6.5" woven carbon fiber cones. Cast frame version
part #55-2321 I don't think they have the cast frame version anymore.
Look like audax HM170CO clones

$50 all

Hi John, I'd like some more info on the Audax PR240-Z0 woofers. The link doesn't seem to work anymore, and a quick internet search turned up nothing. Any specifications you can give me? Is the "95 db" you quoted 1w/1m? What size are they? What kind of shape are they in? Thanx.

They are wanting a vented box ... at 3 CF tuned to 30hz
Two 3" x 12" port gives F3 around 30hz according to quick calcs
