Replace a Bag End woofer after 20 years with this. Almost wish I had blown it years earlier. This is a terrific woofer.

I borrowed a pair of speakers from a friend. He bought them new in the 80s. While I was playing a CD, a faulty patch cable shorted out and blew one of them.When I opened up the cabinet and saw the brand, and Made In USA on it, I thought two things: that the company was probably out of business by now, or if not, that their manufacturing would be in China, the land of crap.Lo and behold, not only is Eminence still in business, but they still make their speakers IN THE U.S.A.!!!In 3 days I had it in hand and installed and sounding just as awesome as the original.Great products. Great prices. Made in a great country! Buy it.

I was looking to get a speaker replacement for my guitar amp and wanted an EV 12L. The guy at the music store told me about this Eminence Delta Pro 12A speaker and said it would be a good substitute and be a lot cheaper. So I tied it. I was knocked out by how similar it sounds to an EV. If you're looking for a good speaker replacement for your guitar cabs or combos...look no further. This will let your amp shine in a very uncolored way!
