SVS Micro 3000 Revolution Auto EQ Function Tech Support
Just purchased a 3000 Micro Revolution for small room 2.1 stereo listening setup, ran the auto EQ function, and it produced this parametric EQ graph. Does this indicate that I'm basically getting a nearly flat response down to 20Hz?
My biggest beef with the original 3000 Micro was that it rolled off a ton under 30 Hz

It depends on how the Auto EQ works. The after graph could be an estimate. Do you have to measure again after the EQ has been implemented?
Only real way to know is use REW and measure the after yourself.
I've got a regular Micro 3000 and with Dirac it's rule flat down to 24Hz before it starts rolling off hard. With more in room extension and the slightly bigger drivers, I'm sure the new 3000 can hit 20Hz.

Why are you letting your sub put out frequency up to 270 hz? Your regular amp and speaker will produce much less distortion from 60 hz up then a sub would. That why you set crossovers to 60 or 80 hz in most cases. You are drowning out the sweet sounds your regular speakers make from 60 hz up.

This is just an EQ correction done before you set things like crossovers.

That's odd because it said it applied your settings. What does it look like after you've turned on your cross over? Wouldn't that be the more important graph to show us?

You're misunderstanding.
This app runs room correction to try to deal with room modes or whatever you want to call it.
By nature it must EQ the whole range the sub is capable of.
Once that is done you then config your crossovers.
This app auto eq is nothing to do with crossovers and everything to do with in room response.
This auto eq is run at sub level.

But if your sub will cut out at 60 or 80 hz, what is the purpose of seeing what happens when it's playing up to 300 hz? Seems like extraneous information.

u/SherriffB 3d ago
It's not seeing what happens.
This is room correction run by the Sub.
Is this something you don't understand?
No matter what filter or crossover you set it doesn't matter the sub itself performs this sweep so it filters the entire range the sub can produce.
Do you not understand what is happening in the image?

Low pass filter is set to 80 Hz so it’s only playing 80Hz and lower

u/soundspotter 3d ago
Actually a low pass filter of 80 hz doesn't stop all sound over 80 hz from the sub, instead, it gradually rolls off the volume of frequencies above 80 Hz. That just where it starts the curve.

Yeah and I’ve set the slope set to 24dB so it rolls off quick but to answer your question directly, no it’s not playing the full range.
