I used to be a car audio enthusiast so i know a little about bass but thats it...anyways..
when i play really really low tones.like 1hz for instance, i hear it coming out of all my speakers..*6 bose speakers* as well as my woofer.
Will these subsonic sounds hurt my non woofers?
or does my reciever have a built in filter to cut them?

It depends on the receiver.

Looks like a good value, at least compared to my receiver I bought for the same price 4 years ago.

If you set the speakers as small at a reasonable crossover frequency your speakers aren't going to be damaged unless you turn things up a LOT. That's what I say anyway.

I guess i set the the frequecy within the mixer? i havet even cracked the book open yet.

What source do you have that plays one hertz?


What speakers do you have the reproduce one hertz? Surely not Bose.


You believe can hear one Hertz? It is physically impossible to hear one Hertz even if you had a way to reproduce that frequency. You are obviously mistaking some other frequency, such a 100Hz, for one Hertz.



Sorry, Matt, I don't think you know much about bass.

The one I have actually experienced is from Crowson Tech. It uses a special amplifier that is designed to operate in the subsonic range. I watched the Pod Race scene from Star Wars and was amazed at the subsonic frequencies that are present in that sound track.

To answer the OP's question: you don't want your speakers playing frequencies they were not meant for. This generally increases distortion, and can result in over-excursion (bad).

Your receiver however does have a built in crossover to pass low frequencies to your sub (and block higher ones), and pass high frequencies to your speakers (and block lower ones). The standard crossover setting to send material to your sub is 80Hz, although depending on your main speakers, you may choose a higher or lower frequency than this.
