Speaker settings.

Large or Small speaker settings on a receiver have absolutely nothing to do with the size of the speaker. It determines whether your receiver is going to send a full range signal (large) to your speaker or a filtered signal which is cut off at the crossover point (small).

If running with a sub woofer, you should set all of your speakers to small.... irregardless of how big they actually are. Start by setting your crossover in your receiver at 80 HZ (THX recommended setting), run a new sweep with this set up and see how it sounds.

If you try to run your mains as large with the crossover set at 80 Hz on your receiver, the mains will ignore the crossover setting and play full range. Depending on how low they go, you could very easily (and most likely), end up with an un natural bass hump in the 80 HZ range down to where your mains roll off. Depending on the phase of the sub, you could also get a total cancellation in that range as well (if the sub and mains happen to be out of phase with each other) and open a whole nother can of worms.

Just set your mains to small, crossed at 80 and then tweak from there. The mains will will be allowed to play everything above 80 HZ without taxing them with the lower bass stuff. If you find your sub is working too hard or unable to handle 80 HZ and down, you could try setting your crossover even lower to say around 60 HZ. But again, remember to keep them set to small.

Take your time and be patient. Each room is different acoustically. It will take a bit of tweaking to get everything to sound just right.

Your speakers are more than capable of being crossed at 60Hz. I would leave it at that, and take some of the load off the sub. In fact, I bet your mains could probably be crossed at 40Hz. That would allow the sub to just have to handle the lowest frequencies.

No problem.... I learned the hard way after ignoring the manual and tring to just set it by ear and what I "thought." What a joke....

I would also recommend using not just the audessey set up in the receiver, but also an SPL meter. You can pick one up from Radio Shack fairly innexpensively. I would recommend an analog unit over the digital one. They are more accurate.

In looking at your speakers, you really could leave them crossed at 60 HZ very easily (just be sure to still set them to small though). That would tax your sub a couple less octaves and allow it to do it's thing even better.

Like I said, take your time, test different settings, make sure the phase is correct and you will end up with settings that are the best for YOUR room. Which of course, will lead to a LOT more fun watching movies.

Good luck!

Double check your sub's manual but.....

Typically, the crossover setting on the sub is for when you have the sub connected via high level speaker inputs. IOW, you are sending a full range (also already amplified) signal to the sub via speaker outs from the receiver.

When sending the sub a low level signal (the single sub coax cable from the sub out on the back of the receiver which is not yet amplified), you turn the crossover off on the sub and assign the crossover point at the receiver. This is usually done by turning the crossover knob all the way to the right.... but like I said, double check your sub's manual.

High level connection = speaker wire = use crossover at sub.
Low level connection = single sub cable = use crossover at the receiver.

I hope this helps....

The difference between 80 and 60Hz is less than an octave. An octave is equivalent to a doubling of frequency... so 60Hz is 1 octave down from 120Hz. 40Hz is an octave down from 80Hz, etc.

ok so a follow up question to the original posters question.

i am running a pair of paradigm titan monitors up front, along with a cc-190.
and in the back i am running atom monitor.

for a sub i have a svs pci 20-39. right now i have the avr crossover at 80hz all around, but i will be picking up a set of monitor 9's and then moving the titans to the surrounds and the atoms to the surround backs.

the monitor9's should be able to handle more bass, so 60hz is possible on the crossover, but i should leave the crossover at 80 on all the others including the center?

Im gonna hook up My television (T5087S) to Yamaha RX-V363, and Yamaha speakers NS-SP1600. I need help with wiring. What kinda Optical cable do i get toslink or mini for my Xbox 360 and my Directv HD DVR. I also am wondering where and what kind of speaker wire I should buy thats not to expensive. My budget for the speaker wire is like 40 bux. I am thinking I should get 100 ft. My living room is about 20' length and 15' wide. I also have cathedral cielings about 11 or 12 ft. high at its highest point. I am also looking for a component wire extender for my Xbox 360 so i can put it further away from my tv. I went to mono price and thats where I saw the different kind of opticals minni and toslink which really confused me. I was also looking at 16 gauge wires but I am not sure thats what I need or if they were the right wires. I need 2 opticals about 6 ft. or 10 ft. Im not even sure how much speaker wire. and a extender to make my component cables longer for my Xbox360. Can anyone help!!! Thanks for reading.

Ok looking for a little help. I recently upgraded my Speakers to Monitor Audio GS10's and subwoofer to Epik Caliber . I set it all up and to make a long story short I ran the Audyssey and came up with this: Distance; front L-6.5ft,front R-6.6ft,center-6.3ft and sub-7.8ft.....Levels; front L & R- +7.0,center- +5.0 and sub- -12.0.......Crossover;center- 40HZ and Surround- 40HZ. My fronts were set at large and the center and surrounds to small.
Ok a little info: The sub is hooked up thru the 3808's sub out to the LFE input on the sub(not left or right line level inputs). The sub settings are set: phase at 180 degrees, volume is around 1-2 o'clock, freq is at all the way over(150 degree). My left and right front are bi-wired.
Now before I used the Audyssey I tried fooling around with the sub and got it to the best placed it sounded the best. I was told that if I used the LFE input on the sub I did not need to worry about the freq knob and was told just to place it all the way over(150 degree).
The sub is alot lower than it did before I used Audyssey but everything else sounds good.
I'm trying to find out some questions: Why isn't the distance & levels for the surrounds not displayed after using Audyssey? Is it suppose to? The crossovers at 40HZ for center & surrounds? Why not the fronts shown? I always thought it should be 80HZ?
My 1st concern is the sub,it sounds really low and not the same thump it had before.
Should I lower the volume on the sub and reuse Audyssey? Just turn up the sub volume to where I like it? Should I change the crossovers to 80HZ from 40MZ on the fronts,center and surrounds(the LFE+main is set at 80Hz)?Before we used the Audyssey I think the sub level was at -3.0.
Any suggestions?
