New To Home Theater: Need Help Calibrating/Setting Crossover Frequency

ravaneli

so the notes over 60 came from the speakers?

Perhaps set all speakers to 80 then.

You must make sure that the speakers can play the bottom end of the signal that you are routing to them. For example, if 50 hrz is sent to them but they cannot play it, then your crossover should be no lower than 60

Would love some guidance with the following set up, trying to integrate in my small/medium size living room set up. 15 feet long 13 feet wide and 8 foot high

Receiver: Onkyo TX SR393 5.2
Front left and right colon Polk audio T50 tower speakers
Center channel: Polk audio Blackstone TL1
Rear speakers: 1990s KLH 4 1/2 inch woofer bookshelf speakers with bass reflex
Subwoofer colonJamo C910

Current settings
Front left and right: 80 Hz
Center: 150 Hz
Rears: 90 Hz
Subwoofer el Effe 120 Hz, crossover max on the back of the subwoofer

Thoughts and guidance would deeply be appreciated😎

Forgive my mistyping, legally blind using dictation that doesn’t always playback well with VoiceOver🌧
: not colon😎
LFE 120

I suggest you get a proper center channel before anything else.

FYI… I don’t have the capital to get a “proper Center channel : Some of us just starting out can’t afford upgrade after upgrade after upgrade, just reality not coveting what others can/cannot do.

So my inquiry stands with what I have not with what I do not.

Thanks 😎

Doesn't that receiver have a room calibration feature? Use it. Personally, I think it works best to have the subwoofer crossover no higher than 80Hz (in the receiver settings) and have the speakers set to the same.

AccuEQ Room Calibration, yep

Yes, ran the calibration, it seems to be all over the place, putting my front speakers which are rated down to 40 Hz up at 200 Hz

Center lower than what it’s rated, typically should be around 125 Hz but at 100hz, there is no setting in avr other than every 2ohz then 50hz increments

Rears are rated at 70 Hz, reads them down at 50 Hz

Sub too boomy need to back it off

Just confusing, don’t want to overload the AVR and the speakers

I'd encourge you to make sure ANYTHING that can make ANY noise is OFF. You need a DEAD quiet house for most to work correctly. I will tell you the super tiny hum my refridgerator made was enough to foul up my results. The microphone also works much better it it is raised up on some sort of tripod. If it is sitting on a couch cushion that can also mess up the results because of reflections or soaking up the tone generated. Regardless your receiver is going to be overwhelmed, It is only rated at 80WPC at only 2 channels. Running the extra channels will drastically reduce its ability to provide enough power to the speakers as it is. You may be down to as little as 25-30 WPC and very close to clipping the signal during movies or surround music.

Thanks, ac and other noise producing off. Don’t have a tripod, not purchasing at this time.

Basic/first time system. Recognizing there will be settling for good enough.

Hoping for general guidance for what I have😎

With the lower end room calibration in these receivers, most of the time, you are better to manually set the crossover points to 80Hz as I mentioned. Then it will apply EQ to balance things. They almost never get the subwoofer volume correct either. I always set that using a sound meter. The key is to run the calibration to get the distances and make sure everything is in phase, then override the crossover points and sub volume. Often, I double check the distances with a tape measure to verify that nothing funky happened.

Well, excuse me for not being a mind reader. Good luck.
