There is a slight difference in running 2 separate cables to the L/R inputs on the subwoofer vs. using a Y adapter at both your preamp and sub. On my system, the 2 separate cables sounded a little better. It's not a big deal and many wouldn't hear any difference at all. I was using a VMPS sub and VMPS ribbon speakers. They have very good definition.
Subwoofer cable question for those in the know...
My preamp has an extra set of line level outputs to drive a powered sub.
Would there be any advantage to running separate L/R cables since it is purely a bottom end booster, or can I Y the signal out/signal in and run just one cable between pre and sub?
Also, what is the difference in construction between "subwoofer cables" and ordinary shielded RCA cables?
I haven't seen anything definitive, and I assume they are designed to carry just a low frequency signal better, as opposed to full range signals?
Advice, of course, is greatly appreciated.

To answer a few different posts and provide some info... I have a JBL 8400P sub and it has both L/R line level inputs, 50-150hZ variable crossover control, phase switch etc. AES3-MKII preamp (made by Cary) which has 2 sets of L/R line level outputs. It is feeding a pair of modded Dynaco MKIV monoblocks. (Must give grannyring some props here. He rebuilt/upgraded these things, and they are beautifully done, as well as sounding incredible. Really nice guy too, as others have said here.) The JBL manual gives as an option putting a Y inline if your pre-out is only a single RCA jack, so I don't see how it could harm anything to Y the connection on both ends, as stated previously it is mono. I have a large volume room with hardwood floors, which makes my sound a bit on the bright/thin side with some recordings. I am just wanting to tinker with the sub to see if it makes the bass deeper without being too muddy/booming, and I didn't want to dump a fortune into cables (it's about a 10-12ft. run from my rack to the sub) just to find out that it was not much better. Thanks for the feedback so far. |

Update: After only 24 hours of burn-in, the Analysis Plus Sub Oval cables have bettered my full-range IC’s going to my sub. The AP’s are tighter and more tuneful in the netherworld under 30hz. This is fairly surprising since the full-range IC’s have a fast attack in the upper frequencies. Both sets went deep. The difference isn’t huge - but, it is apparent if the sub is properly dialed in. And I was anticipating a refund upon sending them back. ;-( |
