But this setting won't send it to the speakers instead, it will just discard what's above
My sub can do 150Hz according to the spec, I chose 120Hz as the spec is probably overrated and there may be some distortion close to the limit anyway, but again I don't think there's info above 80Hz on the LFE track anyway, setting it to 80 (which I think is what Audyssey did) may work just fine.
I think you'd want at least 80Hz for the LFE setting in your case, 60Hz doesn't seem right, but I'm no expert.
I've been studying eq and crossovers quite a bit, but can't be labeled as expert either. But I have learned some lessons worth repeating. First, read up on what the frequencies we are talking about SOUND like:http://www.recordingeq.com/Subscribe/tip/tascam.htmhttp://www.digitalprosound.com/2002/...g_excerpt1.htm
After all, it is up to your ears to tune the system to what it needs.
I used to just set the crossovers to match the range of the sub and speakers, but recently tried a lower sub crossover (60) and found great clarity and definition in bass. The 70-100 range of frequencies contain a lot of bottom end, but if they are emphasized too much, can add too much boom to the mix. That makes you turn your sub down, which them removes a bit too much bass, and then can make your mains too harsh. I found if I lowered the sub content, I could then have nice volume and presence with the low end, but could also hear the 80-120 stuff my nice mains were outputting. The mains also represent a stereo field with these frequencies, as opposed to the sub which is centered.
So listen to your system, define the bass characteristic, and state what sound you are after - is it earth shattering boom, or detailed bass, or something inbetween? Follow the definitions of the frequencies from the two eq links above, and experiment. A unit like the Denon is filled with sound tailoring options, but if you don't understand the language of frequencies and crossovers, it will be very elusive. Besides it's more fun to tweak with purpose and confidence, instead of hoping that a certain setting that someone else uses will make your system sound good. Hope this helps...
