New PSB Setup with Old Sub

[juryman]

Don't even bother using AccuEQ, unless you can limit its calibration below 500Hz. If you can't do that, don't use it.

Not sure there is a setting for that. But Ill check.

My old speakers were set at 8ohm so I have to believe it was AccuEQ that did it.

Nothing too unusual looking except for the little speakers flanking the tv....are those the old speakers? I'd change the impedance setting back to 8 in any case. Don't believe AccuEQ has a way to limit the frequency range like Audyssey apps can. If you can't get AccuEQ to set something reasonable, like shady says, turn it off and just set levels/delays with an spl meter.

Correct. Those are the old Axiom Ti that I am replacing. Just havent had a chance to remove them. Ill try the 8ohm setting.

Are you suggesting I rerun AccuEQ again after the change?

I just really want to get a more reasonable starting spot for my crossover and then tweak from there. Especially on the LR. The XC center is at 40 right now. But LR at 200??? And the X1T can go down to 35hz.

Do you think my turning the crossover dial on the sub to 120hz may be having an effect?

Again, Im still learning, so apologies for all the questions. But as you said, I may have to scrap AccuEQ and just go manual.

OH and find a new sub!

Def reset things manually if able to. The most useful things room correction should do is give you distance and levels. Hopefully you can reset the XOs manually. If so, double the lower number of your speakers range to find a good starting point. So for your new L/R, start at 70, or 80. That Center should probably go up around 100.

You should set the sub to Bypass if using and Bass Management on the AVR, which you will be if setting to Small with an XO point.

I'd re-run AccuEQ after resetting the avr to see if the results change. Not because of the impedance switch change, tho. If you lower the crossover it may leave a gap in the eq if it works like Audyssey does. I'd max out the dial on your sub's low pass filter, even tho some subs have a specific LFE input that will do that automatically. Reasonable starting point to me is 80hz and then experiment from there (both up and down). Did AccuEQ set the delays (distance) for the speakers fairly accurately (it may be slightly different for the sub due the sub's inherent internal processing delay).

I dont think I have those settings. The sub only has Phase, Equalization, Crossover, and volume. Not sure about the RZ820 AVR. But as you said, setting to Small should do it.

Usually, the crossover knob would be set to Max if no bypass setting is available. This keeps the end user from overlapping the XO in the AVR and in the Sub... which is bad.

Sometimes that input that automatically bypasses is called LFE, too. Always safe to max out the low pass filter, tho (sorry, cannot call that a crossover ).

They got other subs too which size you going for ??

This one is way to heavy I cannot even move that with bicep tear injury ...I wonder if surgery is worth the risk .
Little overkill , I’ll never need a sub this robust .

I just had a chance to look at the settings of the AVR. It does not allow me to change the Impendence manually. Its grey'd out, set at 4ohm. So the calibration had to have done it.

Interesting, hadn't heard of such before.....it's a separate setting on all mine.

I might have to jump on the Onkyo forum discussion for my AVR and see what they say.

Basic manual only came in the box. Advanced manual is online and its crap. Doesnt explain much.

Manual states this...

Set the impedance () of the connected speakers.
"4ohms": When any of the connected speakers
have 4 or more to less than 6 impedance
"6ohms": When the connected speakers all have
6 or more impedance.
• For impedance, check the indications on the
back of the speakers or their instruction manual.

I see this in speaker setup on pg 14 of the advanced manual:
in Initial Setup (P24).0If any of the connected speakers have an impedance of 4 Ω or more to less than 6 Ω, after completing Initial Setup, you need to make some settings in the Setup menu. Press "X" on the remote controller, select "2. Speaker" - "Configuration" and set "Speaker Impedance" to "4ohms"

I put in "X" as the little symbol of a wheel/sun (setting button I assume) didn't copy over......is this where it's grayed out?

What you read is actually in the basic manual. Yes, when I scroll through the choices it skips right over the impedance. It is greyed out. Its almost like I need to reset the receiver from the beginning. It does not know that I connected different speakers.

Could be, get lost on which part I've toggled to between basic/advanced manuals of onkyo sometimes. Now I lost track of which avr model it is anyhoo I do seem to remember they lean a lot on the auto setup in that manual, but don't off the top of my head understand the how or why of it in terms of an impedance setting....

 

[Kingnoob]

My Onkyo 818 is old and allows you to adjust ohms , id imagine all but must basic Onkyo allow this .

Good luck !!
My junk Yamaha and Sony htib Amp don’t let me adjust ohms

My 15” diy sub is too loud ima go 12” next time .
