Wiring dual subs

Postby mozart999uk » Fri May 07, 2021 9:58 am

What's the best way to wire in dual subs in my studio (when the subs don't have slave outs)?

I have stereo xlrs out from my monitor controller that currently go into my sub and then out of that into my RL906 tops.

To add a second sub, should I use an xlr y split cable or is a passive splitter box better?

Was thinking to split after my monitor controller.....

I'd rather not use anything with DSP in it . Just a clean split.....

EDIT: I suppose the other option is just to go left out - sub1 - top, and then right out - sub 2 - top. Any implications with bass and stereo with this setup though?

Passive splitting of an analogue feed, either via a splitter cable or a passive split box, is perfectly acceptable. It's why the matched-voltage paradigm we've used for decades was invented!

Yes. You could split the left and right outputs to feed the stereo inputs of both subs (assuming the subs generate a mono sum internally)

This is the option I was going to suggest. It's much simpler and easier from a wiring point of view, obviously, and since most commercial music already has mono bass it wouldn't make any acoustic difference anyway.

But there is also an argument that stereo bass is a good thing from a sense of spatiousness... assuming the room and the sub placement supports it.
