looks like a nice find for sure, what type of amp are you going to use and did you install them yet? I'd love to hear your thoughts. I found these on old school xtr pro 12d4's Ebay, they are supposed to get stupid loud and were designed by TC Sounds. pretty cool if u ask me!

This Listing is for One Sub Woofer each bid. The ORION XTR PRO12d4 ( Double Voice coils 4ohm X 4ohm )( Woofer is Brand New come with while Styrofoam box ) 90 days warranty. This woofer were built before DEI own ORION by TC Sound in 1999.
The woofer has NO Logo sticker on the magnet and dust cap as seen in photo. I have only 1 Orion Logo dust cap left as you can see on the right corner. This woofer will come with plane black dust cap. Because of missing sticker logos that why I sell for this cheap. If the woofer with completed logo that will be $299 each as you all know how much they cost.
The Original ORION XTR Pro woofers were designed to play loud with distortion control.
The Structure, Bigger tinsel leads handle more power. The suspension Nomax system allows woofer move far with great control. The Thicker cone with Santoprene Surround lets the cone move in and out without going from side to side. The 2.5" Voice Coil with 4 layer oxygen free copper wire. The Power Motor Structure creates more bass with the same input power.
