How to cut my sub out of my system with a switch?

[DisasterArea]

I'm using a powered Acoustic Profiles sub which is hooked up in between my amp and speakers, it sounds a treat... But I'm moving into an apartment from a house and I'm worried about booming sub volume during movies disturbing my neighbours.

I'm looking for a way to cut the sub out of my system when I'm watching movies or at night. Anybody DIY'd some kind of switch box for this (or found a cheap off the shelf solution)

If it is an active sub, just switch off its mains power.

Won't the crossover still be active though? The speakers are wired through it, won't it still filter out the low end, even if turned off? It would also be nice to have a more accessible switch as my sub is tucked away in a corner.

The sub just samples the high level throughput to the main speakers.

Try it, switch it off and see what the main speakers do.

Just as KathieandDad said:

Usually, a powered sub just taps some of the speaker-level signal, processes it via a low-pass filter and then amplifies it for the sub.

What goes in speaker-level usually comes out speaker-level, with no filtering in between.

Concerning the switch: Use a switched extension cord or even a (wireless) switched receptacle for convenience. Usually available at any supermarket with an electronics department, or hardware store.

EDIT: Corner placement for a sub is far from optimal, unless it is designed for that or one likes over-present, wobbly bass.

disaster area, have you set an hpf for your mains on your receiver? or another x over in your system?

so your trying to turn off your subwoofer remotely, and then have your speakers reproduce the bass simultaneously? if you haven't set any active x-overs, those woofers are already reproducing those frequencies.
