home theater setup...

[gride]

so i just inherited some older(2005ish) equipment. here's a list of what i've got
denon 3805
b&o 8000(front l&r)
b&o 6000(surround l&r)
velodyne f-1200 b sub
denon 1901 dvd
miller & kreisel v75 II(unused)
apple tv(gen 1)
2 sony 200cd juke boxes
mitsubishi 50" plasma(no hdmi-has component and dvi-d inputs; 1080i)

all the video is switched on the receiver using component cables and all the audio is digital optical, but the dvd is using digital coax. the b&o's are setup with the line input's as well as the sub. the center channel is the only passive speaker. would i prefer a newer tv and receiver, kind of, but i couldnt afford a new receiver that is on par with the 3805 or similar quality of the speakers.

should I use the dolby proIIx or dts neo 6? or will that apply to each source differently like dvd, tv, etc?
i have all the speakers set to small @ 80hz. i've read the sub frequency should be all the way up since i can't bypass its crossover because the receiver sends the bass that would go to the fronts to the sub from having the fronts set as small. is this correct, or would i want it at 75-80hz? it works, but i can't get a good consensus on which setting is best for movies or the sub frequency setting. i can tell you that cd's sound awesome in digital pcm 2 channel(pure direct mode). If i didn't already have a bit of knowledge on this i'd kill myself hooking all this stuff up and adjusting everything.

sorry for my rant. it's been so long since i've heard music through a proper setup and im loving it. pink floyd, traffic, and mariah carey sound awesome.(i also inherited about 240 cd's)

If your mains are at 80 and higher, you want your sub at 80 and below.

If you can adjust output to each speaker, try to find someone with a spl meter and adjust your speakers' relative volumes to match at your optimum listening position.

Again, avsforum.com is your friend.

ya im debating buying an spl meter for $50 or spending $100 to have someone who reallys knows what's up come set all the individual frequencies and surround settings, db. i say $100 b/c thats the hourly rate. i initially had it at 80hz, but a few home theater posts i read said to bypass the sub crossover or turn it as high as it goes. that's because with the small speaker settings any "bass" is sent to the sub. with it all the way up it kinda seems like it's just thumping every sound, but still sounds nice. at 80hz it sounds very similar, but seems like it's got less going on as far as receiving those higher frequencies. i meant dolby digital PLII, not PLIIx.

I can't remember precisely, but I think I have my high pass set at 120 hz. My receiver does an auto adjust with a microphone in the listening position. I have Klipsch in the front and center and 8" Yamaha ceiling speakers in the surround and rear surround position (7.1). Running a Dayton 12" sub and it hits well for the big bass, but doesn't interfere with dialogue. I ran an spl meter and had to adjust the bass up a bit

I think the part about maxing the crossover is doing it on the sub itself and then using the receiver to tweak the settings.

i am referring to the sub's internal crossover. it's not a passive speaker. 120hz is too bright for me in the house. unless you're using auddessey auto calibration you really aren't getting a good auto tune of your system. they will get close, but doing it manually with noise and meters is much more practical.
