Quickie subwoofer question
« on: August 24, 2018, 03:36:55 pm »
I want to hook up a B&W sub to the Quickie.  Is it ok to split just one of the outputs with a y adapter and send it to the sub, or should 2 be used?

Best to sum both channels, since the bass is still in stereo.

(Well, OK, older vinyl records often blended the deep bass to mono, but you can't count on it - especially with more recent recordings.)

Most sub amps have stereo line-level inputs, and the amp will sum the channels internally. If yours doesn't, look up this thread on the Audio Asylum:  https://www.audioasylum.com/forums/tubediy/messages/26/264261.html

Perfect, thanks.  I think the sub has a left and right input.  I'll try that.

If the sub has a speaker level input, I would recommend that connection over the line level option when using a Quickie.

I just contemplated this same question last week and almost asked about it here but turned to google instead, when i got some Omega Speakers Stick 6's in test. These have active hemp sub's in bottom half.

Some higher end subwoofer and sub/speakers combo manufacturers recommend to use high-level input, gives you better sync with main speakers thus a better sound quality.

A lot of active subwoofers have very low input impedance, so moving this load to the power amp instead of the preamp can improve system performance.
