Hardly overrated. Yeah, I've got a somewhat strange setup, but I'm not crossing my M80s at 100 or 120 just so I can get bass from my surround channels (QS4s). Nor am I crossing my QS4s at 40 Hz and losing all the bass from those channels.

Gotta have multiple crossovers. I have no idea why more manufacturers have not implemented them.

I think they all have them, but on their upper endish models to force us to pay more for other thngs we don't want. Eventually it will trickle down.

I bought an SPL meter at lunch today and went and verified my audessey settings.

All speakers were at 75 db with the excepetion of my right surround. I lowered it half a decibel in the denon to acheive a 75 db reading on the spl meter.

The sub was set at 9 o'clock during the auto set up (and it still is)and the denon set it to -12db. With these settings the spl meter read between 75 and 77 db (it was fluctuating).

I feel better about the channel level calibrations that the denon produced (and the distances were spot on too.) But I still think I want to experiment with crossovers for the mains.

Right now the settings are how the denon put them- the surrounds are set to small with crossover at 80, the center is set to small with crossover at 40, and the mains are set to large.

The sub is set to LFE+main with the 'crossover' at 60 hz.

For 98% of my music the bass level is perfect at -12. When I want to give the sub a workout and show it off with a little rap or drum n' bass I can crank it up to -3 and man it is LOUD (and a bit boomy at that point).

However,I feel like I am missing some bass during action movies and games. I think I need to experiment with both the crossover and the sub placement. I was hoping for my couch to rumble during explosions, and right now it is not.

I need to find a good HD-DVD or DVD to test the LFE...

I think you need to set the sub's crossover at or over the highest crossover for the channels, otherwise you might be missing that 60-80 Hz range on the surrounds. At least, that's how I have my H/K set up. Maybe I'm insane.

kcarlile, you mean to change it on the sub from bypass to 80hz?

I have seen some discussion on this in the forums but most have claimed it made little difference.

I would like to optimize things as much as possible but am somewhat apprensive about changing too many settings (like crossover, or the LFE+main, or large vs. small).

I also don't know if I have to adjust the crossover and other settings for each input or not.

I can have a different crossover for stereo mode vs. surround mode, but I do not know If changing the crossover under the HD DVD input also changes it for the DVD or xbox input...

No, the sub should be on bypass (afaik), but the sub's crossover in the setup you have listed is 60Hz, no? That's the one I mean.

No the LFE is set to LFE+Main with a crossover at 60 but the individual channels are set to surrounds - small and 80hz, center is small and 40hz(very odd here), and mains large which is where the LFE+mains at 60hz comes in.

terzaghi, I would change that center to something more like the surrounds, it is a VP series center right?

I think the place that the LFE+ main crossover was at 60 hz was for stereo mode only now that I think of it.

I don't think it would make sense to have an option to set the subwoofer crossover when they have the option to set the crossover for each speaker.

and yes, the center is a vp150.

For some reason the audessey set it to 40 hz. Maybe some of the bass that could be directed to my sub in the 40-80 hz range is getting stuck comming through my center.

Ter,

My couch used to shake, rattle and roll when I had my 600 set to 80 Hz and by-pass (read my post on bass earlier today). But with the changes I've now made, I feel "punches" rather than "booms".

I'll give you an example. When watching LFODH's apartment shooting scene in the beginning, at 80Hz I heard a very "thick" rat-a-tat from the machine gun and what I felt was something boomy all over me and around me. But at 40Hz, I heard a totally realistic machine gun staccato and felt that sucker right in my left butt cheek through my leather couch \:\) . In the U-571 depth charge scene, at 80Hz my whole couch shakes. But at 40Hz, I feel the sharp impact of every blast. And when one of the charges at the start of the scene falls in the water, I very clearly hear the sound of water being displaced and then getting sucked in as the barrel submerges. Sort of like what you hear as you finish off a can-opener in the water. But with 80Hz, that subtle yet oh so cool effect vanishes.
