Conclusion: I purchased these to replace a pair of TS-W254R's. Wish I had purchased these 264's first. They sound great and are rated for another 100watts RMS which gives me a little cushion before they cook.
Conclusion: I purchased this subwoofer to replace a JL audio wx series 10. This pioneer is amazing in an enclosed box. Im using a 1600w Autotek mm amplifier at 800w rms . I broke the subwoofer in for about 2 weeks and only have the amp half way up and the spl is fantastic which I am huge on. I would definitely purchase this again. Sonic is great and i received the speaker within a week of ordering it.
Conclusion: WOW is all I could think after listening to it the first time. I installed it in a Fiat 500 with a sealed fiberglass box and the sound that comes from it is equal to the JL 12" sub in my other vehicle.
Conclusion: Very nice solid bass. A little too tight of a sound in a sealed enclosure of 0.75 cu feet, but can still rumble low, I'm sure it will unleash potential in a ported enclosure (which Pioneer does say is okay to do, recc. at 1.1 cubic feet). Seems to be made of mostly plastic on the entire exterior, but probably helps with the weight of it. Solid product that can kick hard and fill up my entire chevy impala.
