Can you connect the PSW650 to both the speaker level inputs AND the LFE input from the preamp processors LFE output? Iím looking at the ownerís manual for the PSW650 and I think that it is one of the suggestions if I understand it correctly. Here is why I want to do this. My main speakers are the RTi150ís, which are awesome, but the PSW650 will go a little lower. I have taken the advice from Polk and configured the front speakers on my pre/pro to large. I have connected the sub to the speaker level inputs from the main amp. I have adjusted the low pass filter to 40Hz and volume of the sub to blend with the mains for 2-channel audio and it sounds great. Currently I have the sub on the pre/pro (Outlaw Audio 990) set to none and for Dolby Digital and DTS it still sounds great. But the amplifier and front speakers have to deal with all that bass from the small center, surrounds and LFE channel. My pre/pro has a setting for the sub of LFE Only which would send the small speaker bass and LFE channel out the sub output. If I could direct the LFE and small speaker bass to the sub so the front speakers didnít have to deal with it I could get the best of both worlds.
