I own a pair of ebony RP-280Fs that I bought on sale, just over a year ago, directly from Klipsch. When they arrived, their boxes seemed intact but worn from storage. I thought their sale price was ideal then so I snatched a pair. I thought I'd be happy with these but they have failed to satisfy my ears. I've had them connected to to my Denon AVR-X4000 and a formerly owned Yamaha A-S2000.
My problem is that one of them seems to not have any of the horn function as I only detect the two woofers operating. When I raise the volume halfway, somewhat abruptly, I am finally able to activate their proper function. This is an intermittent issue.
Does anyone else have this problem? Could this have been the reason that they went on sale? I thought about upgrading to RF-7 III's but I've got to fix this speaker first.
