Review on 🔊 Immerse Yourself in Deep Bass with the OSD Nero 8" Trimless In-Wall Subwoofer: 200W Sealed Enclosure, Magnetic Grill - FS800 by Mark Jefferson

Not as good as I thought. The metal mount is different than what is listed in the instructions, but I've installed hundreds of devices and speakers in the wall so it was pretty obvious. The speaker is connected to the Crown amplifier and doesn't sound that loud. but it's "good", it's good for the price, and it's hard to find good in-wall speakers. The metal bracket sucks, although it rattles, no matter how I tighten it will rattle after a while so I tried siliconizing the screws and speaker. everything in place and left it on for a few days and then a few more hours of film, after which it started rattling again. you screw them. They start to go a little tight, then just turn it on and they'll match the crappy mount/rethread it. Since then it hasn't rattled at all.
