I've had these for about a year now. I got a pair of these Almanis to replace the left and right rear speakers in my '93 Lexus SC400. Those original speakers, part of the Nakamichi sound system, had both failed for some unknown reason, though the other five original Nakamichi system speakers and subwoofer are still working fine, knock on wood. I got the Almanis mainly because there was a good price for them on eBay and they happen to fit the oddball size speaker enclosures on my car, and have about the right specs to replace the originals. Well, I put them in and my rear surround came back nicely. I tested them out by fading all the way to the rear to listening to them alone (plus subwoofer) and although I wouldn't say they sounded outstanding, for rear filling they are just fine. The materials in the Almanis looked to be fairly durable, and construction quality seemed good.
