Black subwoofer amp is designed for those systems that require the highest power levels with the lowest distortion and most comprehensive features. Up to 1,000 watts are available into 4 Ohms, allowing for multiple 8 Ohm subwoofers to be connected simultaneously. Where the installation demands that the subwoofers are hidden in Walls, Ceilings, or Outdoors buried in the ground, the SAM500 is the right choice. Ten presets have been programmed into the SAM500 to allow users to easily match the most common set-ups. The crossover points and filter slopes have been carefully chosen to guarantee a great match for your existing main speakers, soundbars, or TV. There is no substitute for a big amplifier and large subwoofers when deep bass is needed. Movie and music soundtracks are recorded with bass going down to 20Hz and below. TV’s soundbars and small speakers cannot reproduce these sounds. Even most large speakers cannot get below 35 Hz. To hear what the artist intended, an amp like this, and speakers to match, are required.
