Great purchase
These sub woofers are still kicking in my truck. Unbelievable sound and thump for the buck and exceed many that cost much more.

Great Sub
This was a good sub, had to sell for a bigger one. but great boom, very clean, and great price! you defintly will hear a difference, you can easily run it off a 250 watt amp and still get plenty of boom.

Best bang 4 buck!!!!!
You can't go wrong with Orion!!!! I am running 600 watts between two of these in a 2.4ft sealed box & this has people thinking I gots 15's. Perfect for a starter system.

Great Buy
I grabbed two of these on special a couple months back. Put them in a sealed 3ft. cubic box. They hit lows very well. My rear view looks like its having a seizure when the lows hit. High notes make my friends react in pain. I have HFi 3000 at 4 ohms, about 800 watts a piece. They dont get warm on the cone at all. They have very sturdy speaker connection and my amp stays frosty also. Just ordered the re sx 18 to replace them. Nothing wrong with them, just get bored after awhile.
