Conclusion: I bought this sub for a subwoofer project for my room. I have the sub hooked up to a Dayton audio plate amp at 4ohms so it getting 240watts rms. in a about 3 cube sealed box. The woofer has a good xmax (nothing too crazy) and it adds a nice bass response to my home system. The only real con about the woofer really isn't about the woofer.
Conclusion: I just had this sub put in my caprice & the bass this sub produces, already has my rear view mirror falling apart, very clear & clean base.....I have just one 15 inch sub , hooked up to a Diamond Audio amp & a capacitor ......Pounds very very hard !!!!
Conclusion: I originally wanted two Orion XTRpro woofers to match up with my old Orion 2150SX amps (1 per woofer @ 600RMS)... My budget didn't allow it, so I got two of the Cobalt 15's to hold me over until I could upgrade. These are really nice subs, and sound great. I've got them way over powered as rated and they handle it well.
Conclusion: Who knew that entry level subwoofers could perform like this... These woofers will absolutely blow your mind. With a bumped back plate, extended pole piece, large magnet, and high roll surround that give an astounding 10.25mm of Xmax deez s***s bang bro....
