Crossover frequency settings confused?

[Roscoe187]

Hi

Setting up my crossover frequency on my receiver for my klipsch speakers, but confused at the specs of the speakers.

Klipsch R-14S Specs
Frequency Response: 83hz - 24khz +/-3db
Low frequency extension 78hz
Crossover Frequency 2200hz

R-25c Specs
Frequency Response: 82hz - 24khz
Low frequency extension 74hz
Crossover Frequency 1800hz

R-28f Specs
Frequency Response: 35hz - 24khz
Low frequency extension 32hz
Crossover Frequency 1800hz

Which specs do I go by. I'm guessing R-14s and the R-25c set at 90hz and the floor standing speakers at 60hz? My amp recommends 90hz for the R-25c and 120hz for the R-14s and 60hz for the floor standing speakers that seem right?

Thanks

Use the "Frequency Response". Let's use this example:
Klipsch R-14S Specs
Frequency Response: 83hz - 24hz +/-3db
Low frequency extension 78hz
Crossover Frequency 2200hz

"Frequency Response... +/-3db" means: "This speaker can play within these frequencies with a volume consistent enough that you can't hear any variation."
It's generally accepted that people can't hear a volume difference of less than 3dB. So from 83Hz to 24kHz, this speaker volume is essentially flat. (Note: Your "24Hz" is a typo... should be "24kHz".)

"Low frequency extension 78Hz" means the speaker can play down to 78Hz, but the volume drops so it's not a loud down there as it is from 83-24kHz.

"Crossover Frequency 2200Hz" is the crossover built into the speaker to split the signal between your woofer and tweeter. You have no control over this and is really just information for a speaker designer kind of guy.

So to answer your question, use the "Frequency response 83-24kHz +/-3dB".
You know the volume of this speaker starts to drop at 83Hz.
You would like your sub(s) to be fully engaged by this point, and you know the crossover you set in your AVR is not an immediate or square wave kind of cutoff... it's a slope.
So if your subs are capable, I'd set the AVR crossovers for this speaker at 100Hz.

Follow this logic for each speaker. And check your numbers for the R-28f. I think there's another typo.

Awesome mate cheers, yea I edited the the post now with correct values. The sub I'm running is the R-10SW klipsch
Frequency response 32hz - 120hz
I have that set at half gain and at 120hz on the sub and receiver settings at 120hz.

What receiver are you using? Its generally okay to raise the crossover in the receiver beyond that "suggested" by your automatic setup routine, but generally you don't want to lower that crossover.

The gain setting on your sub is one thing but what value did your receiver set the subwoofer channel level for? You have the LPF of LFE set at 120?

Onkyo tx nr747. Yea the receiver set the LPF of LFE at 120.

Given the spec's the R14's and R25's should be fine at 90Hz, while 60Hz for the R28's sounds reasonable.

How about sub level?
