Hello guys. My gaming system: Xbox 360 PC for flight simulator with a complete cockpit simulation. Samsung un55es6500 LED. Harman Kardon HKTS11 5.1 which is 8 ohms.(the subwoofer is 200 RMS). I need to buy buttkicker LFE 950 watt http://item.mobileweb.ebay.com/viewitem?itemId=121100109475&index=6&nav=SEARCH&nid=82951374312. to my setup system but i saw the buttkicker says in it specs ( 4 ohms and 2 ohms only). Is this mean not compatible with my system ( which is 8 ohms ). Or don't worry about that and start the ordering. Thanks alote.
