No offense, but if you don't know what the MTX Black Golds are, than you probably won't want them. They were the SQ sub to get back in the 1990's, before MTX went to poo. Now, 15 years later, they can still compete with the best of em, require very little power and very little space. They are also very rare which means they have as much nostalgia value as they do car audio value.pics and specs.
