Crossover settingS??

So been trying to figure out what my crossover should be set at. I find quite confusing is setting corssover and ect for speakers and a/v receiver. I have this receiver http://www.crutchfield.com/S-JzkYoQX...-TX-SR702.html along with this 5.1 speaker set http://www.bostonacoustics.com/US/Pr...ostonAcoustics) Think currently I have the crossover on all surround speakers (front and back) at 80 center at 80 and the sub is at 150 or 160. I found that gives me a fuller sub without being too overpowering. But the one issue I see and I am not sure if its just me but dialog audio seems a little faint.

That's an awfully high crossover for a sub.

"Faint" dialogue is probably unrelated to crossover settings; it is much higher in frequency.

What should a sub crossover be then? I was trying to find the lpf/lfe setting for it but couldn't find it. Is 80 for the other speakers a good crossover for that system? I am rather new to all of this so any help would be greatly appreciated. Know my Onkyo could run an auto set up with a mic but I didnt get the mic for set up with the system.

Your links didn't work.

For the faint dialog, try disabling Audyssey DynamicEQ, if you have that.

I do not have an audyssey set up. Don't know why links didn't work but receiver is Onkyo tx-sr702 and speakers are Boston Acoustic cs 2310 5.1 speaker system.

80 Hz is a good starting point for all crossovers. If the bass is OK just leave it there.

Try setting up Audyssey if you have it. You could also try boosting the level (trim) of the center speaker.

When you say the sub is set to 150Hz or 160Hz, are you referring to the knob on the sub itself (which should be set to the maximum value so 150Hz is fine) or are you referring to the LPF for LFE setting on the AVR (which should be somewhere between 80Hz -120Hz)?

I have the knob on the sub all the way up as I seen thats where most work best. The 150 160 I was talking about the sub setting under the eq on my avr. Think the sub eq has a db setting (seems to be separate from the speaker settings although don't notice much when changed) and 40,80,and 160hz settings. Then the individual speakers (center ext.) have similar settings in different hz raitings (don't recall the ranges.) Unless that is the lpf/lfe I am not able to find a setting for lpf/lfe and I do have my sub connected through that port.

The default is generally 120Hz although very little LFE above even 80Hz, so 150Hz or 160Hz isn't going to matter.

Not familiar with your model, so can't say whether that is the LPF setting not, although if the only possible values are 40Hz, 80Hz, or 160Hz, then I'd set it to 80Hz.

And am I correct think I also read that all speakers should be set to small and crossover for surrounds left right and center should be 80. So the sub and surround left right and center should be same crossover? Sorry very new to this and there is so much info, find it kind of overwhelming.

Edit I found this don't know if it will allow you to understand speakers I'm using more.

The sub has no crossover and the only way the speakers might have the same crossover is if they are all the same speakers or have similar characteristics.

Those are pretty small satellite speakers. If you cross them over at 80hz you're missing most everything between 80 and about 120hz. 120hz is the lowest I would go with those speakers.

The front and rear surrounds are all the same I believe. Only different ones are sub and center (although they are also CS series)

I will try 120 and see how that works out. So if I understand this correctly by setting the crossover to 120hz everything below 120hz gos to the sub?

The mfr spec'd low end of the frequency response of those speakers is only 120Hz, so you'll want to set the individual speaker crossovers at the next highest setting above 120Hz (eg. 130Hz or 140Hz).

Is there a way to set individual crossover or is the only crossover setting the one in the speaker set up where you set size etc?

If your model does not allow for individual crossovers for each speaker then the one setting would apply to all speakers.

Thanks this has all been very helpful. Now I just need my optical cables to come in so I can get doby sound. Currently only have RCA's hooking receiver to the TV audio out. Thanks again, sure I'll have more questions later lol.
