Well,I know what are you talking about,because the first time that I connected the third bass(yeah,the famous Magnavox)the bass power came down drastically,and the trouble was the phase so I fix it and matched better. I have the three subs in the same corner of my bedroom. I have the opportunity to buy an used Klipsch SW8 II,what do you think about this sub...and with it's kind of connection,do you think that it can be hooked to the LFE...Thanx!
