Rockville1500w 15" Raw DJ Subwoofer 4 Ohm Sub Woofer 70OZ Magnet, 15 inch (RVW1500P4), Black

This was a perfect replacement for an Altec Lansing ALP-L2200. (Might also include Gemini GSP-L2200PK) Altec no longer supports the L2200 speakers. A multimeter showed the old blown woofer was .40 meaning 4 ohms, this woofer fits, and operates well and the clarity sounds perfect, maybe better than the original. Install took me less than 10 minutes with an allen wrench and screwdriver. Looks better in the enclosure than the old silver one IMO.

Used this speaker to replace a speaker that was cutting out at higher volumes on a Harbinger vari 4115 loud speaker. It installed vary easy using existing hole pattern. Sound is surprisingly good for the price. I would not hesitate to use this speaker again for this application.

I have ten of them

These where used in a dual15 inch box ....they sound great bass hits hard ....but I cranked them a little to much one of them is popping already but other wise well worth the money ....well made also

Great sounding on a Behringer keyboard amp that had a bad speaker. this one sound great...

Christmas. Happily purchased 7 brand new speakers for the family systems. 6 were totally defective. Great Christmas, huh? Two were so bad, Amazon refused to ship them. Two both had missing tweeters. What, like no one would miss all the high notes? Some professional studio monitors, huh? Now these two big Woofers, both are off center by nearly an inch. Looks like no one paid them any mind while the glue was wet & they slid way off center. They DO sound ok, even though they are obviously defective. I kept them but I hate them & will never trust off center speaker manufacturing. Lard heads...Another Three Hundred bucks to fix that mess.

I used this to repair an Alto TS315 that had blown and it works great!

I use this product for music.. but you all forgot the rubber fitting that goes on the outside of the speaker..
