Help ... Totally stuck (subwoofer topic)

Hi, folks. Hoping you can help me here. Earlier this year I got a JL Audio e110 sub for my two channel system. Using a pre/power combo - no receiver. Set up is B&W N804 speakers, BAT VK-3i preamp, and MF A300cr power amp (225 wpc). Old equipment, I know, but it sounds really good. There are two issues which I can't quite figure out.

First, I use the second output on my preamp into the line level input on the sub. I DON'T use the sub's line out into the power amp because the sound becomes very thin and unengaging. Essentially, I am running the mains full range with the sub doubling the bass. JL Audio specifically recommends that the sub's line out be connected to the power amp's inputs for a better sound. However, that's not occurring in my system. Any thoughts on why this is happening?

Second, in the configuration I use, I find that turning off the internal crossover actually brings a fuller, louder sound with more detail. Am I unknowingly biamping with the sub used this way? Seems like a waste not to use the crossover, so I have no clue as to what's going on.

I am really stumped by this, and could use your collective help. Thanks.

I also use the JL e110 for my 2 channel rig, an SA Moon 600i integrated with Focal L&R Utopia Be loudspeakers. Speakers are run full range out of amp, using set of preamp outs to the e110.

The speakers have a -3dB at 45hz rating and I have found my setup to sound best with the Focal rear ports plugged and the e110 crossover set somewhere between 35 and 40hz.

I agree with plutos about the Soundoctor setup guide, I have the cd and all paperwork from him and it is definitely a huge plus for system setup.

Hope this helps, it may take some time but once everything is dialed in I think you'll find the e110 will be a nice addition to your system.

Good luck and Merry Christmas!
