Cross over help

[SPH]

I have an onkyo 606 t90 fronts rt 400 srr and a cs2.

I have the fronts bi amped.

Right now I am running it like this.

fronts 40
cs2 80
srr 40
sub 80


It just dosent seem warm enough. I had the cs2 set on 60 but it sounded as though the voice (mens voices) were distorting, could have been just me.

What brand of speakers? They must be rather large to set crossovers so low. With the distortion you're getting, sounds like they are set too low.

That seems too low. What do the specs say for the speakers?

Fronts:
Frequency Response 38Hz - 25kHz
Nominal Impedance 8 ohms

Cs2
Frequency Response 55Hz - 25kHz
Nominal Impedance 8 ohms

rt400
Crossover frequency: 3.5 kHz/1.9 kHz Frequency response -3 dB points: 50 Hz to 20 kHz/45 Hz to 25 kHz

I wouldn't go lower than 80 all around with the sub at 120. Might be the combo of Polk & Onkyo thats bright. Thanks. Semper Fi

+1. Set your crossovers at 80hz. You can go down to 60hz on the fronts if you really want, but let the sub do the work. It'll balance things out and sound much better. It also happens to be THX recommendations.

As a general rule you'll want to give 10-20hz from the spec sheets for rolloff so you don't end up with audio holes.

set the sub at 120 and the rest at 80

Set all speakers to small and your crossover to 80hz make sure your crossover on the sub is all the way up, always let your receiver set the cross over never set it manually on the sub yourself.

Fixed on speaker size, but the receiver does have variable crossover settings for the individual speakers. I have the sub set all the way open (on the sub amp itself)

I would recommend setting all speakers to 80hz, by doing this all speakers bellow 80'z are being sent to the sub, this will produce a more even bass, and you will be using the sub how it was intended to be used.

By individually setting each speaker to different crossovers you can actually produce overtones, this is caused by the different bass frequencies being produced by different speakers and clashing with each other and can make a muddy sound or even cancel out certain frequency range. Setting different crossovers is more for advanced users who know how to fix this problem. It's always recommended to set all speakers at 80hz this usually produces the best sound for Movie watching, now for listening to music this theory can go right out the window.

so with all speakers at 80hz what would the ideal crossover for the sub be?

The crossover on the back of sub should always be at the highest setting, setting your crossover on the receiver to 80hz for all the speakers sets the sub to handle everything at 80hz and under. You should never set the crossover on the sub itself unless your receiver can't set crossovers for your speakers.

ok got that, the corssover on m y sub is set to the highest setting on the sub but what about the setting in my receiver? On my onkyo 605 there is a setting for LFE has a setting much like the speakers do. i currently have it set at 120hz in the receiver, should it be set lower?

Yes you should set that to 80hz as well. now after doing this you should run you setup again.

Keep it at 120.

+1, I asked this question some time back in the AVS forums, and was told for my 605 to have all speakers at 80hz and the LFE set at 120hz. I do not remember why, but this has always sounded balanced to me and I have never messed with them since.

this could be the case with the Onkyo, i'm not that familiar with the 605. From experience it should be set at 80hz.

Doesn't matter what brand, if you leave it at 80hz you lose all the bass above that crossover.
