We took this home theater from a best buy special with a single 10” subwoofer to a hard hitting cinematic experience. Our client emphasized that he wanted to cause structural damage if he wanted it and we delivered! We installed four Toby 18" subwoofers, powered by four 3000w amps, and 500 watts rms for the front and surround speakers to try to keep up. To be honest we were even blown away by the level of bass and dynamic range this system delivered it makes you chuckle and say wow. Up front is a acoustic transparent 120" screen with Cinénova Clarté speakers, and seating for the whole family bringing this theater to life.
