Give Steve at RD a call. If you aren't impressed then come back on here and post. He can tell you in detail every part on every sub and why he went with that part. He knows his stuff, and from what I have seen he makes incredibly solid products. But I will be able to say a lot more as soon as I get my 12" Alpha in next week and power it with the SAZ-1500DBecause RD sucks. They have overly pushy sales people and they dont have very good choices of people to rep their products(or I mean other companies products) lawl and they go off some cheap gimmick(the Super Gluez)
I guess Pyle makes good products because i can tell you they are known more than DD RD FI and RE put togetherNo i stick with more reputable brands sorry.
