Great speaker, used for a replacement on a blown subwoofer on B52 Pro PA system, sounds crisp and loud, hits harder then the OEM, had to modify the original speaker box a little to accommodate the larger magnet, solid product, solid brand.

This thing is barking! I used this to replace an older damaged speaker in my older baltic birch 1 X 15 bass cabinet. This thing is a serious upgrade, it handles the power of my amplifier easily and is clear as a bell whether I am banging on the low B string on my 5 or soloing way up on the neck. I have been playing bass for over 40 years now and owned many speakers and cabinets and this speaker is one of the very best I have heard. Delivered on time with no hassles and easy to install
