Room correction

[slartibartfast]

If you turn off all the boost frequency, would it sound dull?

I only correct up to 500Hz so probably not. I am sure it would sound different though.

 

[rccarguy]

Yes 20 to 20khz.

Generally it's best to do <400hz that's where the room effects the sound the most.

Try also 4khz, that what Anthem ARC uses.

less is more when it comes to RC you don't want to be aggressive.

Here is full range sweep of my towers, you can see where you want RC to concentrate on.

I just followed what rccarguy to see how it sound. I will just going to enable them back. I don’t think it’s a problem for halo jc 1 knowing it’s one of the most powerful and expensive amp that ever made. It can drive any speakers known to man down to 1 ohms.

I have 300W ATI amplifiers, but it's still not recommended- as you're pushing the drivers harder to compensate. If you do boost I'd keep it to within a couple of db, don't go mad with 10db boosts, with many filters with high boost.

With all 10 bands enable, sound was great than rc off. I think rc have gone a lot of under the hood improvements. I like soundstage that is large as monument. In some occasion, I use Yamaha dsp to give the soundstage as large as palace at 360 since it uses 4 speakers to simulate dsp while the main just produce direct sound. It uses 6 speakers. Main speakers produce direct sound while the other 4 a combination of early reflection and reverberation. I’m one of the very few who like dsp but mostly users stick to straight mode.

From my experience Yamaha DSP is crap (I have a Yamaha AVR) the stock DSU/DTS decoders are fine, but it's the extra gimmicky DSP modes which are rubbish. Too much reverb and it makes it feel you're listening in a bathroom or nightclub

If you have a chance checkout Lexicon Logic 7 music surround with old Lexicon processors, those were brilliant. It expands the music in such a way it's subtle. Can also adjust the front/rear mix, and the surround roll off etc, you might not want the rears to be full range, so you can adjust it to say 12khz. You can adjust the amount of center mix, my preference is most goes the L/R with only a bit to the center, so it's like halfway between 5.1 and 4.1 phantom mode.

I will limit to those range. Thanks!

Majority doesn’t like how dsp sound and your right the reverb and echo is not something most listeners want.

One thing you DON'T want to do is boost below the F3 point of the speaker, ie if you try and boost 20hz-80hz on Kef LS50 (and running full range also) you'll blow the woofers out

Small speakers like that are not meant to drive them or feed them on insane level of power. What they need a separate subwoofer to make them sound full. Tower speakers with multiple array of 7 inch could handle a load and can go deeper. Preferable 4 drivers of 7 inches.

Why does AV receiver it’s nearing to zero volume and barely loud? Unlike wiim ultra just few click it can frighten the wildlife.

Huh?

You mean the calibration tones? Make sure it's not that loud you can damage speakers during the sweep.

I use fixed level to my pre amps . I don't use variable

I connect the Yamaha AVR pre out to external amp rated 450 watt at 8 ohms and 850 watt at 4 ohms. When I listen to John Lennon imagine it’s just barely loud. However, wiim ultra on same external amp it would blow the woofer on my power hungry Polk legend. Is Yamaha pre out putting out low voltage?

Have you run the Yamaha avr calibration? With the Yamaha mic? Generally you'll find when the display on the Yamaha is -10db that's when it's quite loud.

When you use the wiim into the Yamaha analogue, coaxial or optical out into the Yamaha use fixed level 100% as the Yamaha is master volume.

With modern avr gear yeah you have to set volume quite high -30db isn't that loud for example and it probably shows down to-65db so a lot of the volume range doesn't do much

It was suggested from the first days of the arrival of the ultra and the sub function
classically... orders and types

(sorry not the ultra but...the amp in 2023)
