here is some rythmik rew porn. dropped my mic to ten in control panel instead of 100 and ran some sweeps at -12.5, -7.5, -2.5, and 0 MV

attached one no smooth and 1 smooth 1/6. only way I think I could get them to play louder would be to increase gains on sub or go past 0mv or increase bass trims in avr...but I have all that set for a reason lol.

anyways pretty good and no funny sounds.

did I mention I like rythmik subs?

Lookin' good, Torii!

However, in order to see if you are compressing or not, you should raise the level by the same amount for each sweep, I use +3dB. Curious that you mentioned only 4 sweep levels, but you have 5 traces in the graph(?). Also, you said that the first 3 sweeps were +5dB each...the graph does not reflect that. You should label the sweeps to make it easier to read the graph.

Keep going until you see compression, OR start hearing any funny noises. You should be able to top 115dB without issue.

yea, i started with channel 3 but then after some runs decided to unplug speaker cables on cc as it was getting loud. than I couldnt get any louder and started messing around with -18db adjustment in rew dropping it by 6 down to -3db.

I will have to try again and take the volume limiter off my avr at 0mv

also a school bus drove by my home on a few of my runs(open front window) so may have had some audible outside noise get into my readings.

I was hoping I could get over 120 db, but not at the settings I have set up now. but also no bad sounds, so that means I still have some room to go

^^ Also try your sweeps on channel 4 instead and up your lfe on your receiver to 250hz.

I do the sweep with Channel 1.3 but run only from 10 to 250 Hz.

I start with RMS Level dBFS @ -20.0 and MV @ -15. Towards the limit, the RMS Level dBFS would be @ -3.0 and the MV would be +5 or so...

I wonder if audyssey or something else in rew holding back my volumes...like maybe everything set to be calibrated at 115 max spl or something and if I should turn audyssey off when doing sweeps for this purpose...I was just trying to find a safe way to see what the limit of my space/equipment was with rew.. I know its louder than what I showed, just dont know how to show it with rew.

but just for fun, I cant play stuff over 120 db for more than a song or 2 anyways...and dont want to mess around too much with settings cause I have it sounding good right now at modest to loud levels.

plus my huge space its hard to get loud thats why im so impressed with fv25hp. no idea on how it compares with 18 inch subs, but it works awesome with my 15hp imo.
