Axiom Home Page Forums General Discussion Technical Questions Bass below speaker freq = distortion or nothing

Ok I believe you are skunked on bass management since you have only one 90hz cutoff frequency for the low-pass filters. But your bigger problem is whether it can drive the 4ohm M80s at any reasonable volume. I suggest you consider a more powerful modern receiver with bass management that allows variable crossovers.

I played WOTW at -15 for about 5 minutes starting at the lightning scene to where the robot comes out of the ground and kills everyone. It can handle the 4 ohm load no problems.......so far.

I think that I might just upgrade my receiver instead of looking for other "Christmas" ideas right now.

Alex, as I and others suggested to you in a earlier thread, your 2200 should have plenty of power for the M80s in nearly all uses, and this apparently is the case for your use. So, there's no compelling reason to get a new receiver for reasons of power, but the features of the 2200 are a bit dated and if you want changes made in those a new model could be justified.

I think that I'm just going through the upgrade bug right now. I need something new, but just don't know what it would be.

My receiver does everything that "I" need right now and I don't think that I should upgrade until I really need to do it.

Agreed. If you want something that will really make a difference, spend that money on a bunch of new CDs and/or DVDs so that you can enjoy the sound of your Axioms more.

I had a Yamaha until recently and, although you could technically set it to BOTH and SMALL, the manual states that the crossover will be used (sub will get the bass). However, it did not say if you would end up with more bass (3db) because of channel doubling or not. But, to go back to the topic at hand, the bass under 90hz (my old receiver's hard-coded crossover) will go to the sub.

Been a while since I posted an actual "real information" response.

For Yamaha receivers... there are two types of "bass" - lets call the stuff rolled off under the 90Hz crossover "bass" and the stuff in the .1 channel "LFE."

Your speaker size determines where the "bass" goes... if you set the mains speaker size to large - the full dynamic range of the program audio goes to the mains. If it's set to small, then it gets sent where the BASS mode (menu 1E on mine) tells it to:

SWFR - both LFE and "bass" go to the sub
MAIN - both LFE and "bass" go to the mains (even if you set the MAINS to SMALL)
BOTH - LFE goes to the sub, "bass" goes to both the mains and the sub.

Hope that clears that up?

Thanks for the informative post BrenR. My question now, is what's the difference between LFE and Bass?

LFE is a channel. Bass is a set of frequencies.

I always thought that Bass was LFE.
