Goldwood 5 8 Ohm... I replaced the bass speakers in an Optimus (Pro LX-511) pair I use for sound field fill in a surround system. I'm happy with the results, but I had to space these speakers back away from the aperture because their foam surrounds touched the edge of the cutout. I used grommets (0.330 OD, 0.156 ID, 0.270 High), 1 at each mounting screw, didn't tighten the screws. To assure the screws would not come loose, I put RTV on them. (See photo) Been using the system for 2 weeks, no buzzing; checked screws, all OK. I will track performance and report any long term degradation of the speakers and mounting system.

Replaced the woofers in a pair of LX5II with rotted surrounds. They are rear-mounted and fit easily, with a good seal and enough clearance for the slightly wider surrounds, thanks to the gasket. (Driver is actually centered, but looks off in the pic due to camera angle.) I soldered the wires due to different sized connectors. Easy repair.My original LX5 drivers are 6 ohm, these are 8. They sound fine for our purposes (low volume background music,) but a more ambitious person would probably want to modify the crossover accordingly. Not sure how they compare to the originals (because the originals have rotted surrounds, obviously.) Goldwood also has a 4 ohm version available.Great price for the pair

These Goldwood speakers fit perfectly in the original speaker box. They are a full range speaker with 70 watts rms rating. Used these for the surround sound center channel. They have very good sound quality at a good price for a pair of them. They arrived quickly and in good condition.
