Powered Speakers / Subwoofer Connection Question

[dcx4610]

Quite a simple question but hopefully someone can answer and provide some insight.

I recently purchased a 2nd SVS PB-1000 Pro subwoofer to use on my PC/gaming/music computer and the question I have is related to how to connect the subwoofer. Single input or dual?

I have powered speakers (Audioengine A2+) and since I'm not using a receiver in this setup, my question comes down to the LFE/RCA inputs on the subwoofer.

Right now, I have a single subwofer cable coming from the right output of the speaker going to the right/LFE input on the subwoofer.

Since I don't have a receiver on the PC and it's just a stereo setup, would I gain any benefit or would it be more proper to have RCA cables going to both the left and right outputs on the speaker and left and right inputs into the subwoofer? Does a single subwoofer cable make any difference versus a stereo cable in a stereo setup?

Hopefully that makes sense.... Thanks.

I doubt the L & R outputs are full mono so yeah, I would connect both the L & R outputs of the speakers to the L & R inputs of the sub. You could also try a bi-directional y-adapter to merge the signal to one (2 RCA into 1) cable and connect to the mono input on the sub, but the results could be mixed.

I also have 2 x PB1000 Pros in my mancave HT/gaming/PC setup. There are times when I have the TV on but I also want to game, so the TV will play through the HT and my PC though a soundbar, which I have the stereo outputs on the soundbar connected to one of the subs just like I described above with the y-adapter. But I had to get a bi-directional y-adapter of good quality for it to work correctly.

Based on the setup you've described, it seems like you're doing just fine with a single RCA subwoofer cable running from your right output speaker to the right/LFE input on the subwoofer. In a setup where you're using powered speakers without a receiver, there's actually no need to split the signal to both left and right channels for the subwoofer.

The reason is because low-frequency sounds, which the subwoofer handles, are typically not recorded in stereo. So even if you ran two RCA cables (left and right) to your subwoofer, you wouldn't notice much of a difference.

In fact, your SVS PB-1000 Pro subwoofer is designed to handle the situation exactly as you've got it set up. The right/LFE input is specifically made to accept a mono signal from a single subwoofer cable, which is exactly what you're providing with your setup.

So, long story short, you should stick with your current setup. A single subwoofer cable is more than sufficient for a stereo setup when it comes to handling low-frequency sound.

Hi guys, sorry for being irrelevant to this thread but this forum is not allowing me to post my questions.

I have one question regarding my powered speakers.

There is an input jack behind it named "Phono".

I have tried researching it on the internet but I am not able to understand it.

Can you please help me?

Phono input accepts an output from a turntable. However, the turntable has to have a built-in preamp.
