Need help on configuring receiver and subwoofer

[weezz]

My Receiver is a htr-5760 (770 watts) by yamaha
my speaker satellite/subwoofer system I'm using is a sa-ve367t by sony (speaker watts 120 and subwoofer 135 watts also its a bass reflex speaker system, the subwoofer has a bass boost feature also)
on my subwoofer it has a level knob, bass-boost knob, and a phase selector.
But i notice that i dont have a crossover frequency/high cut on the subwoofer.
On my yamaha receiver i have a crossover frequency that goes from 40,60,80,90,100,110,120.160, and finally 200hz
on my sony speaker manual it sayz if i have receiver with a adjustable crossover its recommended that i should set my crossover to 150hz.
I've have notice i cant set the crossoveer to 150hz so i have to set it 160hz.
I 've also notice that i sometimes get unwanted sounds like people voices or in other wordz some unwanted sounds/bass when i set it 160hz, i should only get bass sounds
My subwoofer reproduction frequency range is from 26hz to 200hz
and my speaker frequency range is 100hz to 27,000hz
I know that this is too much explaining
but can somebody please help me with this problem on figuring out a good crossover to set on the receiver and how to set the volume knob and bass boost knob to a good level so i get a good tight bass response rather than to much bass.

If you have the Star Wars Trilogy or some other movies like King Arthur, they have the THX optimizers that can give you a modest test of how well you are set up. If your speakers only go down to 100, set the front speaker size to "small" and your crossover at 110 or 120.

set the volume on the bass to about half when you run your tests.

Does it specify how many db down that 100hz is? If it's waaaaaaay down, morethan -6, then those little bitty satellites really can't reproduce it with any authority. That may be why sony recommends you set the "Sub" to 150 and rely on it to pump out the mid and upper bass.

Those tiny mains simply can't get near 100hz. I'm pretty sure if they could, Sony would recommend a lower Xover frequency.

This is not a dig. Many little satellite speakers in combo systems can't.

Reciever setting

Go to you reciever set up menu>Manual Setup>Sound Menu>Speaker Set>Bass Out. Make sure your bass out is set to sub and not both.

Hope that helps

Oh and keep your x-over to the speaker recommended setting.

Ok,
i turn my bass boost knob on my subwoofer to a half.
do you mean db in my sensitivity level???
If so it sayz
sensitivity level: 84 db

and for my crossover setting when i put it to 160hz (because i cant put it to 150hz)
it sounds like to much is going into the sub
like mid sounds of somebody's voice (if you know what i mean) and unwanted bass
i called sony about my speakers and they dont give good advice
so i called yamaha, even though the speakers ain't by them
they said for me to turn the crossover seting on my receiver to the THX recommended setting
which yall know is 80hz.
when i turn it too 80hz my sub sounds better, unlike setting it to 160hz
please tell me if yall think im doing something wrong.
is it also good to keep the bass and treble on the receiver high or on bypass???
and also what is an easy defintion for understanding crossover frequency???

whatever sounds better to you is the way to go, just make sure you're not missing any sound. you won't be hurting the speakers any.

Crossover is the frequency where you send the low signals to the sub, and the higher signal to your front speakers.

At a low crossover frequency like 80, the mains do most of the sound work and your sub happily makes explosions and tyrannasour footsteps.

At a higher crossover frequency, some action sounds and lower men's voices begin to spill from the speakers to the sub (as you have already found out). this can be very distracting, as the sound doesn't sound like it's coming from where the action is, and you inadvertantly follow the sound and don't look at the screen.

The lower you can get the crossover, the better off you are as long as you aren't missing any of the sound because your front speakers don't reach low enough to fill on top of the sub (ie if you set to 80, knowing they can only reach to 100, you are missing all the sound between 80 and 100. it's being sent to the mains, but they simply can't reproduce it.)

ok,
so you mean if i put the crossover frequency on the
receiver to 80hz (knowing that my satellites speaker range is 100hz) (100hz-27,000hz)
I'll be missing sound???
If that'z so then should i put it to 100 hz or a little higher???

 

[Leprkon]

If that'z so then should i put it to 100 hz or a little higher???

I'd go the first step you have above 100 and see how that sounds compared to 80.

 

[weezz]

tell me something
even though my subwoofer doesn't have a crossover/high cut frequency switch/knob
is that bad???
also my speaker manual says that my little satellite speakers
enclosure type is bass reflex???
if anybody has a yamaha with the ypao
why does it always turn my LFE/BASS OUT to both??? and my crossover frequency to 160hz???
is it mistaking it self or is it because of the enclosure type???
and also about the my bass boost knob on my subwoofer (to any body that has a bass boost knob on their subwoofer)
can I do good without the bass boost knob???
if so should I turn the volume up some if I turn the bass boost off???
also is it best to turn my receiver sub volume off and use the subwoofer volume???
PLEASE HELP THIZ NEWBIE

I agree with Leprkon about the x-over. Bass reflex is just a marketing term like "low distortion" or "bass boost". Keep your bass out to sub or LFE, the only time it would be both is while listening to music w/towers, not H/T.
I would suggest using your sub volume control and not you reciever, leave the bass boost off, use a spl meter and if you cannot get adequite volume turn on bass boost.

Hope that helps some.
