Ｍｋ- v75滿足不了你喔
這棵不錯可以考慮
就算搬去友人約三坪的空間試
也沒什駐波
因為它有ＴＨＸ模式（真的很好用）



The 272 PBM sealed enclosure subwoofer creates an impressively solid bass foundation for your music and movie special effects. It employs a massive 12" long throw driver with a full 2 inch, 4 layer voice coil and a 9.5 pound vented magnet structure. The built-in 225 watt amplifier is a fully discrete design, with a large torroidal transformer for efficient high current, high level drive. A precision 18dB per octave variable crossover with a bypass setting ensures smooth integration with the satellites and eliminates any possibility of audibly localizing the woofer. High and low level inputs with pass through connectors make it easy to connect the 272 PBM to virtually any home theater electronics.
