onkyo 605

[SPH]

I have recently ordered some new speakers. The cross over rating for the center is 25mghz and the new fronts is about the same. The lowest crossover point I can set my sub on is 80, but the rest I can set lower.


I am at a loss on why it only goes to 80 and what will I be best served to set the crossover to.

I have also noticed this on my 605, scratched my head why the sub cannot be set below 80hz but I'm certain that there's a very good reason for that as the sub produces a bit more (little) bit more than just the nether regions of the frequency band. Plus, the other speakers although rated at those Freq's, aren't all that efficient in those very low regions so the sub needs to be a bit higher in Freq to cover a dead or shallow spot in the Freq's.

Generally centers are crossed over around 100-120 Hz. Mostly dialog comes from the center so you don't need it to hit really low.

wait... are you saying the internal crossover is at 2500hz? If so, that means at 2500Hz the speaker sends all frequencies above that range to the tweeter and frequencies below that to the woofers (in the same speaker cabinet)

On the Onkyo the crossover point is where the receiver stops sending through the signal. So if crossed at 100HZ, anything below 100Hz won't be sent to the speaker.

As for the sub, cross it over at 80 Hz in the receiver and set to direct (or the highest possible setting) on the sub itself. Sub crossovers eliminate sound above the frequency you select.

sorry added an "m" to the hz..


Right now I have everything set at 100 and the sub at 80, but wanted to be sure I am wringing out everything I can.

I think I am going to start looking into separates and a real crossover.

At those settings you have a 20Hz gap in your soundfield. Drop your Front left and Front Right channels to 80 Hz. That will allow you to hear everything.

I had heard it is best to set your sub at 120hz and Direct on the sub itself. Is this wrong?

[Slec]

There's not right or wrong. I've heard people recommend it be set to 80 in the receiver and 120 (same as direct) on the sub..

I find 120Hz far too boomy.

[SPH]

Yeah I set the sub to, the highest x over limit, and 80 in the receiver.


I admit that I may be able to change the settinggs with the new speakers. I bought monitor 60s (t90e) and a cs2. Right now with the center I have which only has one 4" and a tweeter setting it much above 100 makes it sound really thin.

If your using the LFE output on the 605 connected to the LFE input on the sub, you can turn that crossover knob on the sub all you want and it won't do a thing. That knob is only functional for line level inputs, not LFE.
