I called a local dealer, and asked him how much the 1515s were. He said that they were 219, but he was willing to negotiate the price. But he also said that it was a single voice coil. Is that true? I didn't think any subwoofers were still single voice coil.
Lol, there are still a lot of single voice coils out there. How much power are you planning on running in your system? I'll tell you one thing that DD isn't cheap but you get what you pay for in this instance in my opinion.
