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.

Lucky dog. Great sub choice. You paid a premium for those excellent crossovers on those E110s so I would try running the preamp outputs through them first. This relieves the power amp and loudspeakers from heavy low frequency lifting. It will take some time and tweaking to get the sub integrated to your room and system but this is what I would do if I had a E110 or two.

On the other hand, You didn’t describe your system so my assumption is that you’re looking for bass extension, probably using stand mounts and not trying to get a few more low freq hertz out of big floorstanders.

In any event it’s your system and your ears so you may enjoy going back and forth between the two options. Have fun!

Have a read below. It cover the E112 which is the 12" version but the theory of using that Linkwitz-Reilly Crossover is explained.

Good luck and keep us posted.



I'm fairly certain that you will use your 2nd pre amp outs to the E110 directly, then you will be able to set up the sub using the external controls to adjust the E110 FULLY (you are going to have xover control)! Sending another pair of signals from the sub out, makes no sense in your system. Great SUB choice too BTW :-)

Thanks, guys. I’m running a BAT VK-3i into a Musical Fidelity A300cr dual mono amp (225 wpc). Speakers are B&W N804s, and I’m looking for a bit more "oomph" in the bottom range. Does this make a difference in how to connect the sub?
