Setting up my Onkyo 805!

[DTS-HD]

Ok so i ran the Audyssey and when i go to my speakers settings where

Fronts=full band
Center=40Hz
Surround=70Hz
LPF of LFE=80Hz THX

Is that right? Its sounds pretty good but im pretty sure it can sound better

[DonRSD]

whats your setup/speakers?

[solarrdadd]

I never use that setup for my system, I've got all my speakers set to large. What kind of speakers do you have?

[DTS-HD]

Fronts= Infinity P362
Center= Infinity Beta C250
Sub= Velodyne Vx-10
Surr= Sonys

most who arnt happy with the auto calibration use a spl meter to calibrate thier system

I would recommend 80 hz for all speakers, and 120 hz for LPF of LFE. Also, you should have some distance between your front speakers and the back wall. Looking at your setup, I'd say give it atleast 6".

[DTS-HD]

oh ok ill put them all 2 80Hz

So whats the differences sorry im kind of new 2 all of this lol

Just to clarify, do you mean 120 Hz set as the cutoff on the actual subwoofer controls? If so, then I agree with you. Set all your main channels to 80 Hz, and make sure your actual subwoofer control is set higher, so you don't lose any audio information. Your receiver won't have to work as hard, and your bass will sound tighter this way. Having multiple low frequency cutoffs in your system is less than ideal.

All of these look suspect to me. For the fronts I would go wth 80Hz as suggested by sheedoe. The center is really odd. 40Hz is below the spec of the speaker. I have a C360 and Audyssey (well actually the 805 since Audyssey just reports the measured frequency response to the AVR) set it to 120Hz. The Sony's no less than 80Hz, but I am surprised that the 805 set them that low.

Get ride of full band(Large) and use your crossovers (Small) for your fronts. Your center's range is 80-200kHz, most will say to give yourself an extra 10-20hz buffer, so anywhere from 80-100 should be OK. But these are excellent speakers, so 80 should be OK. Your fronts state a range of 38-20kHz, which if you use the +10-20 rule would come in around 60hz, but again these speakers are very good and anywhere from 60-80 should be OK. You'll have to listen to it to see what sounds the best to you. I say keep your sub at 120 hz and let it do the job it is designed for with the bass. Not sure about your surrounds, but 80hz is what I would set them to. This is just my 2 cents, but I know others here might be able to elaborate further in much more detail if you desire. Good Luck!

Yeah i changed all my speakers 2 80Hz and my LFE=120Hz it sounds really good now and the bass alot tighter

I would at least run the mic calibration to get speaker distances and the EQ set, even if you decide to run everything as full band.

Yup! This way no frequency is lost on the .1 sub channel.

Ok thanks

Ok i changed my settings and ill i can say it sounds really good the way i imagined it would sound

[DonRSD]

if all the speakers are set to 80hz and the sub to 120hz, wouldnt all the sounds from 80 to 120hz be MORE amplified?

why not set everything at 80hz and everything above 80hz = all the speakers and everything below = the sub?

doesnt make sense to have 40hz worth of frequency overlapping (80hz - 120hz).

Actually, it makes total sense. There's no "more amplification" here. Everything 80hz and below gets sent from the speakers to the sub. Thus, everything is played at 80hz and below. However, you're forgetting the .1 in 5.1/7.1 tracks. Audio specifically for LFE is anywhere from 120hz and below.

If you find that voices or too much bass gets dropped to the sub, a good middle point is usually 100hz. I have my LPF of LFE set at 120hz though and have never had an issue.

[nismo604]

just a couple pointers.

first use the audyssey settings, then with an SPL make sure all speakers are set to 75dbs, for speakers that are efficient audyssey seems to set the trims low, adjust them back up to 75dbs.

Also regarding frequency adjustment just remember that lowering the frequency response to what audyssey has set will not be optimal as audyssey will not have eq'd to that frequency range, however any adjustment to a higher crossover to what audyssey set your frequency is fine as audyssey has eq'd for it.

ok i didnt mean MORE AMPLICATION in that terms. let me try to ask again.

if the fronts are set to SMALL & a crossover of 80hz. then everything BELOW 80hz is goiung to the sub (.1)

thus everything everything ABOVE 80hz is staying in the fronts


as far as the sub it will use all the sounds from 120hz and below



below 80 hz = 1 speaker (sub)
above 120 hz = 2 speakers (2 fronts)
between 80hz to 120hz = 3 speakers (sub & 2 fronts)
you have overlapping frequencies


would this "accentuate" (or whatever the word is) the 80-120hz range to be "louder/boomier" (again whatever term fits in here) than things above 120hz or below 80hz?

Perfect! I just wanted to make sure we were on the same page, and we are. At first I was afraid you were setting your LFE output from the receiver to 120 Hz (instead of 80 Hz), and as I'm sure you're aware, bass becomes directional around 100 Hz and above.

No, it doesn't work that way. The 80 Hz crossover point is set in the receiver, so it won't send frequencies higher than 80 Hz to the subwoofer. It doesn't matter if you set the sub to 120 Hz or 200 Hz, because it won't receive a signal higher than 80 Hz.

The important point is that you don't want to set the sub to just 80 Hz, because if it's miscalibrated you don't want to risk dropping part of the frequency range. Most subs use a manual dial to set the crossover point. If the dial isn't calibrated properly, 80 Hz on the dial might be closer to 75 or 70 Hz. Typically you set the sub higher than 80 just to make sure the sub's built in crossover doesn't filter out additional signal information already set by the receiver.

There is no additional amplification following this process. The sub won't receive anything above 80 Hz from the receiver.
