In Reply to: db difference of LFE vs sub hooked via main posted by magman on May 08, 2001 at 16:30:48:
the LFE output through your crossover to the sub amp. Signal from 2 channel output ...direct to front amp. This requires that both the 2 ch pre and proc get a siganl from the CD player. I run analog to my 2 channel pre and a digital out to the proc. Use the proc to control sub volume when listening to 2 channel. You could also omit the crossover and use your proc if you can. You might need to adjust polarity between the fronts and sub if the 2 ch pre / proc are different. Plan on spending some time integrating your fronts/sub. Note your current positions/settings before you start to change things to make it easy to go back if it doesn't work for you. For low freq I really don't think I'm missing much by using the proc rather then a pre. And it's certainly more convenient then swapping cables!!Good Luck!!!
Follow Ups:
The sub has 24db/oct low pass and high pass, which I use to remove all freq below 50hz from my main speakers. If I understand you, then if I hook up the sub to the proc's LFE and play the bass through there and rest from the pre-amp to main, I still don't remove the low frequencies from my main speakers, and they will result in woofer bottoming(I have magnepan MG-3A, with limited bass excursion) on high bass passages.
