GNS 8” subwoofer
I replaced my outdoor deck system sub with speaker and am very pleased, listening to my jazz on Spotify, I have a hodgepodge system consisting of a Pyle Bluetooth amp some goodwill akai 3ways and an old Optimus r50 home sub amp, this speaker for the money sounds ridiculously good! Nice full punch and very little flab! Great subwoofer for an affordable price

Excellent
Worked like a charm. My subwoofer speaker foam deteriorated and the speaker rattled. This replacement was simple to install. Connectors were the same size as the old one, and the screw holes lined up perfectly. Jusyake sure to match the ohms of the previous one. This one is 4 ohms.

Perfect Replacement Subwoofer
Perfect replacement for the Monoprice Premium Select 8-inch subwoofer! The mounting holes line-up perfectly, and the driver fits the baffle's diameter without any modifications. As for the sound quality, it DOES NOT go as deep as the OEM driver, but at $30 you can't complain. There was also a slight rattle, but the rattle goes away during the break-in process, so give it a few hours of playtime before judging it.

Replacement for existing 8" sub
My old Polk 8" sub had seen better times so I replaced the driver, had to cut about 1/4" dia. of material out to get it to fit screwed it down and cranked it up. It sounds better than I remember the original sounding. Good bang for the buck
