Frequency range of receiver

[Architect1975]

I just purchased an HSU sub that is supposed to go down to 16 Hz. I'm not even sure I can get a 16 Hz signal to the sub.
I have an old (relatively) HTR-5840 Yamaha receiver. The specs that show frequency say 20Hz - 20kHz. The exception is that "Frequency Response: CD to Front L/R" says 10Hz - 100 kHz. Doesn't say anything about other sources, like DVD, or any of the other speakers. I've never really paid much attention until I bought a sub capable of going that low.

So basically, will this receiver even send a 16 Hz sound to the sub?

All of those specs are for the amplifier, not the preamp/sub output. The subwoofer output should do just fine for this, additionally the amplifiers will probably do a little better than the ranges they are speced at.

Good point. I should have realized that. I am using the sub out LFE by the way. I sure wish they would list that in a spec though.
Thanks for the fast reply.

The only conclusive test is to play test tones of specific frequencies. The tones could be burned on a CD or from a computer to any available input on the receiver.

Beware though, to cleanly reproduce 10 - 20Hz signals, you require tremendous power and exceptionally well designed drivers to withstand that power. If you push past the limit, it may fry the sub's amp or damage the driver.

The hsu sub came with a cd. From all the forums i read, it will do 20 hz. When I first got the sub, I didn't really hear anything even at 30 or 40 hz. That's why I started wondering about it. The sub is new so I was taking it very easy on it. Maybe I just need to calibrate it a little and turn up the volume a little. Then I'll try the test tones again. I am really not impressed with the sub so far, but it does seem to be getting better after 5 hours use. Maybe it doesn't have anything to do with the receiver at all. Maybe I have the sub in a bad spot.

You also need to be aware of your ability to perceive the low frequencies. Your hearing is not the same for lows as the mid bands; you need a lot more energy to hear it and at some point you will only feel it. So, don't be down on the sub
