Just picked up some Infinity Reference 2000.6's for mains, 2000.3's for rears and a Video 1 for a center. Should I set my speaker setting on my receiver to large or leave it at small? I've read someone THX said you should always leave it at small and have an 80hz crossover, but I'm not sure. I have a Yamaha HT5730 if that helps. I know it's low end, reciever is my next upgrade. This is my first home theater build and all together with a Yamaha YST SW-216 subwoofer I'm up to $180 for everything. Which last time I checked would have bought me a plastic Samsung HTIB that can't produce half the sound of one of these Infinites.

Thank you! If I was to set it to large and still keep the bass going to the sub (My crossover is 90hz I believe), would I just be wasting power?

Not sure, you can give it a try. Your speakers will play
Cleaner and louder when set to small and perhaps an
80hz x-over. Bass below 80 will be sent to the sub, your
Amp will have MORE power to send to the speakers
Because it is not using watts to produce bass notes.
Your speakers will play cleaner and louder because they
Don't have to play low bass notes.

That was the best explanation of this setting I've ever heard in my life. Well done Grasshopper.

It's confusing, my first 5.1 AVR I set speakers to large
Becuz they were large floor standers. wink.gif

Thanks

If you want you main speakers to handle the bass (ie no sub) you set them to large...

Set up #1: EMP e5Ti, e5Ci, and EMP e5Bi surrounds, Outlaw LFM1 Plus sub, SVS NSD SB12 sub, Marantz Slimeline 1504 AV receiver
Set up #2: Def Tech SM450, CLR2002, SLS Qline surrounds and EMPtek10i10i sub, Denon 1910 AV receiver
Set up #3: Philharmonics- BMR in a 2.0 system, music only, Yamaha RXV-363 AV receiver

I was just looking through my receiver settings and I can set my bass to "Both" meaning front and subwoofer. However when I do I feel like the sub doesn't hit as hard, is this because instead of my front speakers sending signals below 80hz to the sub they're trying to reproduce the bass and only my rears and center are sending an LFE signal to the sub than? Just trying to wrap my head around this.

Your subwoofer is the speaker most capable of producing the under 80hz sounds...

Likely more just because your front speakers simply aren't capable of reproducing those lower frequencies than anything else. When set to "both" I don't know if the sub actually gets less bass/lfe signal than when not set to "both", though I suppose that's possible; the manual really doesn't have a lot to go on here, but the manual implies you should get the lfe/bass to the sub plus whatever your fronts can provide....

Now just wait until you get a sub that can really produce those lower frequencies as compared to the YST216....

This is most likely due to the subs being out of phase with the main speakers and is causing cancellation of the bass frequencies. When you have multiple sources of the same frequencies playing they will either compliment each other (in phase) and increase the volume of those frequencies or they will be destructive (out of phase) and reduce the the volume of those frequencies.

Good point, I assumed he had checked that already.
