They want you to use the line inputs in order to use the sub crossover to remove bass from the main speakers thereby allowing them to be free to produce better mids and highs. In theory. Sounds like that's not working for you. Try using the high level inputs directly from the speakers (or power amp output terminals) This is the recommended config for my RELs.
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.
