Best Subwoofer Connection


OK, so I'm waiting on delivery of a JL Audio e110 subwoofer. I have a 2 channel setup. The on-line manual recommends connecting the preamp outs to the subwoofer's line in (l/r), and then going from the sub's line outs to the power amp. OTOH, I could just go from the second set of preamp outs to the sub's line in and run the signal in parallel without using the sub's internal xover. Which connection is preferred and best for a music only setup? I've searched this issue here, but I haven't found an answer that makes sense to me. Thanks.

UPDATE: The e110 arrived today, and I've tried it both ways. Running the N804s full range with the sub filling in the bottom end is much more engaging amd satisfying to my ears. When I put the sub between the preamp and the amp, the sound became thin and lifeless. Perhaps that's because having one 10" sub to carry all of the lower bass makes little sense in a set up with full range speakers. I could see putting the sub between components when running monitors which don't go down below 60 Hz or if I had 2 e110s. By running the N804s full range, I get the benefit of four 6.5" woofers plus the e110. The sound is very full, although I think I need to get used to articulate bass instead of the boomy, flabby bass I've experienced with other subs. Different strokes for different
folks, I guess.

Well, there you go. Once I saw your current loudspeakers I figured that you would be going in that direction. Still, given the high-quality of the crossovers in the JL E110, you have plenty of options down the road.

And perhaps adding a second sub might change things, too. My plan is to go with two E110s or E112s simply because of something I read someplace about how stereo mastering is now done down to below 20Hz. 

For me, I wouldn't be done tweaking for another month or so. Finding the right location for the sub, pinpointing the crossover frequency, setting the phase and, finally, making tradeoffs on the sub volume setting so I didn't have to get up and change it when the album changed.

On the other hand, you're a vinyl guy so you're used to getting up. ;)

Great sub choice and nice system. (Jealous grin.) Enjoy!

@dbtom2  ... thanks for the compliments on the system. I'm not a vinyl guy, though, it's purely CDs for me. And, yes, it will take some time to fine tune, but that's part of the fun. I think if you go with 2 e-subs, then you might have better luck than I with placing them between components.
