Axiom Home Page Forums General Discussion Technical Questions M3 amplified bookshelf speakers Question

I have two pairs of M3 amplified bookshelf speakers. I want to know if the “sub” output is a summed line out with the crossover in the woofer?

Currently the speakers are getting their signals from my audio interface. What I plan to do is sum the line level signals from all four channels and send it to the woofers from the audio interface directly.

Just want to know of there are in special considerations. As it stands, the line level sent to each channel is -30 db and I would do the same for the summed signals for the woofers.

Line level by definition does not have volume control, so you'll always be adjusting both the M3 and subwoofer output levels at the source and the sub any time you want to change the volume.

I'd personally just use the subwoofer output of the powered M3 speakers' front channels. The convenience is clear and noticeable; any improvement in audio clarity wouldn't be.

If you have existing issues with a ground loop hum, that would be a different matter altogether.
