Qpower deluxe 15"
I've had several of these over the years, and installed 2 or 3 for friends. It is a flea market brand, based out of texas. The sound of the driver in 2-2.5 cubes sealed is very clean with the right amount of power. The ideal install is 2 in 4-5 cubes sealed on 1500w rms, yes rms, 3" coils. I've done plenty of testing, and at the price point of around $100, they simply OUTBEAT kicker cvr's and SOUND BETTER sealed, and really hit the lows down to 30 HERTZ!!. Check out realmofexcursion then brands, then qpower for some of the videos, all though mine sounded like **** because i had it crossed wrong on a ****** eq back then...
