Crossover setting? - Blu-ray Forum

cam555 · 08-05-2008, 04:45 AM

I just did the automatic cailbration thing on my receiver....and it set the crossover on my sub to 200hz? why so high? my sub is a 650 watt klipsch.

jomari · 08-05-2008, 05:42 AM

set your crossover at 80, then compare at 60. work with whichever you prefer.

of course, a spl meter can tell you what your ears cannot.

im just wondering why my receiver automatically set it at 200hz? why would it do that? i have the F3's C3 and S3's....the sub is klipsch 650 watt 12". my receiver is the yamaha htr 6090

allstar780 · 08-05-2008, 08:37 AM

did it set your speakers to small as well? if so it is not recognizing them as being full-band (or large) and probably is trying to send more of the low stuff to the sub, thinking your speakers cant handle it... set the speakers around 80-120 (for your fronts anyways) and the sub the same... see if it sounds better

Automatic calibration programs are not perfect. You may want to run the program again. Make sure you follow the instructions in the receiver's manual. I usually do not depend on automatic calibration alone. I make manual adjustments with an SPL meter. The follwong are the instructions for manual crossover settings:

You need to set the crossover on the receiver’s menu and not the subwoofer. If your main front speakers are full-size with good bass response, set the low pass filter to 80Hz. If your main speakers are small, bookshelf, satellite, or in-wall, set the low pass filter in the 100 to 120Hz range.

Run the test tone generator for intervals between 30Hz to 200HZ and listen to the output level or measure it with an SPL meter. If different output levels are heard or read by the SPL meter for different frequencies, it is quite normal as different frequencies interact differently with the room acoustics. Increase or decrease the low-pass frequency to achieve the smoothest response. Decrease the crossover frequency if there is too much output around the crossover point, increase it if you notice a drop in the response.

In general, if the main speakers are large and capable of creating low frequency sound, it will be easier to match them with a subwoofer as opposed to the smaller speakers that most people own. However, it is not always best to set the crossover frequency at the lowest possible frequency to avoid the sonic signature of the subwoofer. If the crossover is set as low as possible, the subwoofer cannot stimulate the main drivers near their resonance frequency, leaving only the mains as the dominate resonance contributor. If the crossover is set slightly higher, the bass from the subwoofer and the main speakers can reinforce one another resulting in a smoother and more pleasing bass.

Hey Cam
I pretty much have the same setup as you except i'm running f1's as rears and olders s1's as my final rear 2. I want to upgrade them to the S3's that you have, Are you moving your s3's to the rear back or keeping them just as rears later on?

cam555 · 08-05-2008, 02:06 PM

im using the s3's as my rears right now....and im soon gonna add two more s3's for my surround back or 7.1

cam555 · 08-05-2008, 02:07 PM

hey big daddy, im not sure if my receiver will let me set the crossover for each speaker....i think it just lets me for my sub.

BLU STEAL · 08-05-2008, 02:53 PM

make sure you turn the crossover on the sub all the way up you want the reciever to control this setting.

cam555 · 08-05-2008, 03:08 PM

ok...after i do that what do i set the crossover on the receiver to be?

The reason it did that most likely has to do with your room. Your speakers may be able to do whatever frequency, but depending on room setup, furniture, windows and alot of other variables, the receiver will correct it. It may be judging that your fronts and other speaker are only reading 200 hz at the microphone, so its sending the rest of the bass to the sub, which believe it or not can be normal depending on the room setup. Id go with the auto calibration unless you are able to calibrate using an SPL meter, but i would definately not go in and just swich crossovers from ear if you want accurate sound.

cam555 · 08-06-2008, 03:54 AM

ok....i turned the crossover on my sub all the way up to 120hz....now how much should i set the sub volume knob on my sub? Now on my receiver i set my fronts to large, center to small, and rears to small and the sub to 60hz. also on my receiver i can go into my equalizer settings and for each channel i get this.....
63hz
160hz
400hz
1khz
2.5khz
6.3khz
16khz each with a +/- 6 db

and the sub channel with
63hz
160hz each with a +/- 6 db.

what should i put those settings at? please help.

cam555 · 08-06-2008, 02:19 PM

anyones help will be greatly appreciated

Pelican170 · 08-06-2008, 02:21 PM

Dude, you dont listen. go by the auto calibration as it will be much more accurate than what your trying to do.

MacDaddyOJack · 08-06-2008, 02:23 PM

Those are the specific frequencies for which the equilizer is centered. This means that you can boost the output at those specific frequencies by adding or subtracting a few decibles. An equilizer is included in most amps since all rooms are different and cause different nodes and gains in all different frequencies. The best way to determine what number those should be set at is with your own ears (or an SPL meter if you don't trust your own ears!)

Ranger-R · 08-06-2008, 02:33 PM

I have the same sub with the volume only half way up, and crossover setting at 80. Now my 94thx sets my sub at -8 for level and is set for 80 on the crossover. Sounds good at these levels and still very loud. So just some info to pass along.
