Product Details

MK Sound SB-1250 THX Black 12" Subwoofer Speaker, Model SB1250THXBK

The SB-1250 all-discrete amplifier design has exceptional sonic quality and a conservative power rating of 250 watts continuous output. To facilitate easy connection and ideal system integration, the SB-1250 has inputs and outputs for line-level phono and speaker level signals. Separate controls allow you to set bass level and upper rolloff frequency between 40 - 200 Hz, with a bypass for using the filter in a home theater receiver. For optimum room integration and precise fine-tuning of the critical transition between the subwoofer and the main speakers, the phase control is continuously variable between 0 and 180 degrees. SB-1250THX handles the crucial bottom octaves with sublime balance, power and impact.
