TXX-BDC3-8 8-inch Woofer Triple Stack Composite Cone Subwoofer 2" 4-Layer Voice Coil BASV 250 Watts RMS 500 Watt Max Dual 4 Ohm

I bought 2 Bazooka passive subwoofer tubes and just was not happy with the sound from them. I found these Audiopipe 8" 4 ohm triple stack woofers that matched the airspace in the Bazooka tubes so I gave it a try....WOW is all I can say. Im glad I did. Those crappy Bazooka tubes aren't crappy any more. These subwoofers are far superior to the Bazooka subwoofers the bass tubes came with. The bass is so much more and deeper. 2 of these parallel (running at 2 ohms) with a 500 watt mono amp easily can be mistaken for a pair of 12's. Don't sleep on these!

Seller advertised as dual 4 ohm in description and they are single voice coil 4 ohm... I was planning on returning but decided running final impedance of 2 ohms instead of 1ohm and running half power was fine for what im using them for. Would have preferred dual voice coil didn't want to deal with returning them.
