Hello fellow JBL fans. Long time no log in!! I am currently putting together a basic stereo LR set up with an LSR6332 and LSR6312P per side.
Not being familiar with xlr pro cabling I'm looking for some guidance. I'm currently running a Krell KAV 250/A and like biwiring. Are there
any pre-made biwire xlr cables produced that any of you might suggest? I've just started looking and so far haven't found any. Any info
would be great!!!!!

May your surrounds last forever!!!!!!

Hello JBL 4435 are you looking for xlr interconnects or biwire speaker wire. A lot of folks use blue jeans cables and are reasonable in price. I usually make my own. Here is a link for xlr's but they can make you up some biwires too. Also other vendors out there but cannot remember off the top of my head now.

Hey jbl4ever. Thanks for the info. Haven't gotten to the pricing stage yet but the basic cable info sounds great. Forgot one additional question. Do the inputs on the LSR6312P accept powered connections from an amplifiers outputs. I have the manual but it doesn't state one way or the other.
Again thanks for the info!!!!

The inputs are all line-level XLR, not speaker level. Kinda wonder how you ended up with this particular sub.

It's intended to reside at the output of an L-C-R consumer or pro-level preamp device (home theater, mixer, home studio, ...).
You could consider the center channel to be optional. The XLR outputs are hi-passed to (still at line level) to amplifiers or powered speakers.

Could you figure out a way to somehow make this work with speaker level inputs? sure.
There are a lot of crappy level converter boxes for this. Radial may even make a nicer one.
Not really recommended, but possible.

Maybe give the spec pdf a read-through? You can find it here:

The pictures on page 2 might help you determine your options.

Apparently, I'm living up to my username today. Apologies in advance. Have fun out there.
