Pioneer TS-W259S4 10" Subwoofer
I have only had this sub installed for barely a day yet, but from what I have heard so far, I am impressed. I wasn't shopping around for subwoofers that would blow my windows out, and I found this one and its perfect, especially for the price. This single 10 inch sub has great power for just one subwoofer, and is enough to rattle your rear view mirror like its nothing. I have it hooked up to a 1000W peak power, 300 RMS Sony Xplod amp, and the two work well together. I have it in the Sound Ordnance enclosure, and I am very impressed with how well everything works. The first time I drove after I installed it myself, I had to turn the bass level to 0 because it was throwing punches like crazy at levels 3-6. If you're looking for a sub that has great sound, looks great, and doesn't empty your wallet, this is definitely the subwoofer for you. Like I said, I've only had it for 24 hours so far, so I am hoping that it stays that way!
Pros: Price, Sound, Looks
Cons: Nothing I can think of!
