So much better than my old paper 4in speaker, sounds much clearer, overall huge improvement, had to modify the the enclosure slightly, this speaker was about 1/8 of an inch bigger than my old speaker but easily modified the hole and so worth it.

Cheaper drivers out there now that are suitable for the BFM SLA speaker, i used these in prior builds and wanted the same drivers to match the bad layer to some new ATMOS speakers.

I am into DYI bookshelf stereo systems.I built a small mini subwoofer enclosure (5.5 x 5.5 x 12) with a 4 passive radiator and installed a $40 base driver that the manufacturer claimed would work as a mini subwoofer. Well, it did not - the driver at its breaking point at a 50 volume setting.I was about to junk the enclosure but decided to give it one last try after I found the GW-4028/S. I am delighted with the result! I get clean, low base and am able to push 70 volume (Fosi 5.1 100 watt amp) setting before noticing any strain on the speaker. This is a good product that beat a popular brand at half the cost.I will build a slightly bigger enclosure using two of these woofers connected in parallel and maybe an 8 to 12 inch passive radiator. I am very enthused at the potential.

I bought this product for a project that didnt end up working out. I have it to a friend, who was able to use it, and it worked perfectly.

I ordered these for an old juke box. Manual said 5 1/4 inch speakers. This is what I ordered but the mounting holes were closer together then the original speakers. I made them fit so I dont know if it was a standard then or maybe it changed. But they sou d great

These have amazing bass for such a small woofer.Put them in a properly sized, solid enclosure and they will shake the room.They will take most of what a 100 watt receiver will deliver.

Used these to replace a blown woofer in my Polk Audio Rti4s. They're a bit smaller (1/8) than the originals but still managed to fit them in with just a little tweak (bent the place where the screws go in just a bit). The stats are practically the same as the original and the sound was wonderful - nice and full and clean. Replaced both woofers in my speakers to assure parity. Took off one star because they arrived slightly bend around the edges.
