Subwoofer adjustment after ypao test

[lpc]

running ypao shows Subwoofer -10 db and i have SW (Klipsch) volume set to mid point....do i increase the SW volume or adust the db in the Yamaha a/v receiver to increase more base?

i did...did you not understand the question?

Generally you want to use the trim level in your avr if you want to bump up the sub level after calibration. It's more repeatable (if you want to change it only for certain inputs/content) and accurate (compared to the non-defined gain controls on subs) plus easier done with the remote than crawling around on the back of the sub....

ps Has nothing to do with the sub itself being "better" or not.

While I agree you want to primarily adjust in the AVR, I don't think the sub should be at 50% gain, it should be around 75%. I would also say run YPAO more than once and see if it comes back with the same results. I know on my system, I ran it 3 times and 1 was different from the other 2, so I kept the one that came back the same and adjusted from there.

The adjustment takes into account not just the volume, but also the distance away, to create one setting that balances both. Check to see if it set your other speakers large or small, I find mine often sets them to large when it shouldn't.

What would the advantage in setting a higher gain on the sub be particularly? I rarely on a plate amp need even more than 1/3 gain myself to achieve -10 dB trim levels. An avr that sets speakers to large is generally just detecting an f3 of 40Hz, the marketing department at work not trying to insult your packages.

my speakers are set to small and the center is large and i changed the center to small also.....after the test...right now i have set the volume around 75 % and avr is at -9db on the sw.... all speakers are small.

Does it sound good?

 

[lpc]

yes it sounds good....my main question really was adjusting the avr or volume on the sub after the test.....so many opinions thanks

 

[William Lemmerhirt]

Use the AVR.

In the long run it's preference. Depends if you want to do it more than once to an extent (repeatability). Sometimes it can have to do with auto-on for the sub, too.

Myself I run auto setup with the subs set at 50% gain then check to see how close to the rest of the system they are then I fine tune by raising or lowering it on the subs to better match the main system then fine tune it with a spl meter . I like to get the subs as close as I can to the main speakers then I’ve got room to play . After everything is set I usually boost the subs up about plus 3 in the menu depending on source material . It works for my setup it may not for others also have been using a 110 crossover setting that cleaned up some bass issues I was haveing but that another story .

Yeah, it depends on the sub, they're not all the same. My Empire at any more than 1/3 would have been way too much. The SB4K is also only around 40-50% out of consideration for neighbors lol.

I think sometimes when it is turning it to -10dB it is also trying to adjust for some anomalous high peak it found that it could not easily correct. Sometimes that can be adjusted by moving the sub to a more optimal location.

Yeah my Empire is one of the subs I was thinking of.

Yes, many subs vary, but the relationship between trim level and the sub gain is more or less going to be constant. Why you would particularly turn the gain down on a sub for neighbors instead of just adjusting trim level I don't really get....

Full calibration then turn it down. The SB4K has a remote and an app app with 3 presets. I tend to keep it on the lowest of the 3 unless watching a movie. Plus I am always home now

LOL maybe it was the turning down at all I don't get. I'm always home and I never turn it down, but my neighbors can't hear it unless I get pretty silly with the volume control, too

With the old Tempest, you could hear it outside in the street lol, and feel it next door >thud< only. The Empire being sealed and dual opposed, wasn't so bad (retired neighbors). The SB4K is not opposed but has a similar output to the Empire, though it is not the same in the upper range.
