Take it from me, Pyle subs ****. I KNOW from EXPERIENCE! I had 2 12"s in a plexi glass bandpass box. Sure, the shit sounded good to me, I had never heard anything else before. Then I upgraded my power to them, feeding them the rated RMS power, 300 RMS to each. Then bad things started happening. I blew the subs, sent them back, got them repaired, had to pay shipping to and from Pyle 3 different times, and turned my gains down, and they still blew again. For about a month they were good, after that they went. I have now had my RE subs for 2 and a half months, and they never have any problems taking power, hitting the low notes, or nothin!
Moral of the story: PYLE SUCKS!
