DAAAAANG I didn't expect -3dB below 29hz that's AWESOME and with the advantage of GLM plus summing 2x 61's well well well suddenly this truly is a full range speakerMine are close to the back wall but I get -3dB @ 26hz with my 61’s.

You can generally expect that, if you are putting your speakers near a wall(and you should be, if you are using EQ, because it's easy to adjust any undesired boost), the anechoic -6dB point will be 0dB in-room. My 8351Bs(w/o subs) measure flat to 30hz in-room, which is even a little bit lower than their official -6dB point of 32hz. This of course applies to any speaker though not just Genelecs.DAAAAANG I didn't expect -3dB below 29hz that's AWESOME and with the advantage of GLM plus summing 2x 61's well well well suddenly this truly is a full range speaker
Awesome response.
Gotta love GLM and if it weren't for my back, I would be adding a pair of 8361A next year!

How does this work? The blue is the filter that corrects the red peak? And if it was the other way around, i.e. a large dip, then nothing could be done, correct? You can't boost a null.
Yes, you can’t eq the nulls out. GLM tries to level the peaks up to ~300hz in my room.How does this work? The blue is the filter that corrects the red peak? And if it was the other way around, i.e. a large dip, then nothing could be done, correct? You can't boost a null.
Do I have that right?
Yes, you can change the crossover for the subwoofer from the default of 85Hz. For the exact range you’ll have the check the manual of the Genelec SAM you want to use.When using a sub, does GLM allow to set the crossover frequencies and if so from what range?
Second post to make sure you see it as there could be some misunderstanding: This only works with Genelec SAM subwoofers, the end. You can’t use another subwoofer if you want to use GLM.When using a sub, does GLM allow to set the crossover frequencies and if so from what range?
GLM actually invokes positive compensation now, depending on measured response and a priori knowledge of monitor model. Here's 51 response in my rather lively living room before subjective adjustment.Yes, you can’t eq the nulls out. GLM tries to level the peaks up to ~300hz in my room.
Actually, you CAN set a crossover frequency for just monitors, and it works (just a very steep high pass filter). You just have to integrate your sub using something other than GLM (e.g., miniDSP, or use the low pass on the sub itself, feed it a separate signal and use REW to adjust level and phase, etc.)This only works with Genelec SAM subwoofers, the end. You can’t use another subwoofer if you want to use GLM.
I for sure wish it was different, but here we are.

I just set it up with Base Management. I set it to 70 Hz and measured it in REW and the base cutoff is visible (and audible) and quite steep. Just got an SVS SB3000 sub yesterday - going to start integrating it tomorrow...Here I had mind using GLM for room EQ for both monitors and subwoofer.
I’m not sure one can set the high pass filters on the monitors using GLM v4 without a SAM subwoofer connected. Out of curiosity I tried to do so some time ago but was unable to make that work.
Yes that is possible, I've tried it myselfHere I had mind using GLM for room EQ for both monitors and subwoofer.

Please report back! I have an SVS collecting dust, I’d love to try it with 8351’s. What was your thought process in choosing 70 Hz?I just set it up with Base Management.

I have a natural dip in the room around 70 Hz, so I figured that I might be able to minimize it by setting the x-over there and playing with phase to try and minimize it. Turns out the best result I've had so far is using 60 Hz and pointing the sub toward the front wall (the grill is nearly touching it). Pretty flat, punchy base from 100 Hz down to 20 Hz, +-2 Hz. Lots of playing with position and x-over frequencies - using the SVS app, GLM and REW made it fairly easy and quick to make the adjustments. Also putting furniture sliders under the sub (my basement has carpet) made moving it around MUCH easier. Pretty happy with what I have now, but there's always room for improvement...Please report back! I have an SVS collecting dust, I’d love to try it with 8351’s.
