Can you not do the same with eq devices such as the mini dsp?

Yes of course you can, but this is an additional purchase. Does the mini dsp allow you to tighten up the bass?

This is same trade-off with camera controls between the point and shoot camera and DSLR. Our controls are right on the panel. What you see is what you get. Clear and simple. Users do not have to memorize what he has done a week ago, or 6 months ago, or going through the multi-layer menu just to find out what he had set before or even just change the extension.

Aside from that. all the damping control and extension control on our panel have time domain meaning. We can plot it using impulse reponse and you can see high damping has shorter tail. If you use mini-DSP, can it tell you what damping it has used? Can it make impulse response shorter or longer? Mini-DSP is designed to tackle the room problem. Our controls are for controlling right out-of-box frequency response. There is no conflict between the two. We should not even say or hint one is the replacement for another. rcohen uses REW for room EQ and yet he still finds our controls have their value. That is from an actual user experience perspective.

makes sense and thanks for the explanation!! I have not tried using my mini dsp to accomplish this, hence why I asked. I do like the idea of being able to adjust the Q on the bass response on the panel. I was just curious if the dsp was capable of doing this because I wanted to try it on my setup.

Here's the compression sweeps for my dual FV15hps. I cannot find my spl meter to cal my mic higher. Max sweep I can do now is +3MV (read LOUD), anything above that results in REW error. Tell me what ya think.

Something seems a bit off with your calibration perhaps? -0MV should be 115db if calibrated correctly? You have it at 108db?

Looks like you're compressing at the 110-111db? Seems low for a pair of FV15HPs in your small room. Great extension though.

^^ thanks Dom. Good point- Don't know why I am at 108db at reference MV. I ran 8 positions Audessey with 14 hi damping 1 port. It got to be the umik-1 not being calibrated with an spl meter. I don't think it compresses at 111db as I went to a 3db increment from reference MV to +3 MV for the stated reason that REW errors out above that level. The others are at 5db increments. I have another graph measured at +5MV from other subs location (which I didn't like) I can post when I can find it. Do you have compression graphs for your dual FVs you can post?

When running your initial calibration doesn't Brian recommend a low dampening?

^^ I know but I do not like the steeper roll off with low dampening when calibrating as shown in the graphs I posted a while back comparing the three dampenings.

Gotcha, I missed that. Yes, since you only increased by 3db, and you got 3db, then no compression.

Not familiar with REW, but in Omnimic, there is an input level that I can turn down so it can record at higher levels. Perhaps REW has a similar function?

Also, I'd check your calibration with your receiver so that 115 is -0, 95db is -20db, etc.

Unfortunately, I've never ran compression sweeps on my FV's...

^^ I will check REW to see if I can measure at a higher level without having a spl meter. I don't know other way to get 115db @ reference MV. Audessey supposes to do that. I assume your level is 115db at reference after Audessey cal? I ran Audessey using gain match technique, then adjusting sub distances from my avr to smooth out my 80hz crossover area. It shouldn't mess up the level, right?
I am a bit surprised that as an ULF guru as you are, you have not run compression sweeps on your FVs. Time to put the ULF thread aside for a bit to run these sweeps and post?

LOL. No sweeps...but I did do the 10hz challenge (do not attempt this) with the FVs that was thrown out there if you recall.

Truth be told, I really don't like running those high output sweeps...they're very uncomfortable (with my system's capability) to me and the house! It's actually part of the reason why I developed the ULF score...you'll have a ballpark idea of where you're at without having to run sweeps and do the bench racing. I put a lot of time and investment tweaking and setting up my HT, and frankly, don't want to F something up!

I imagine that curiosity will eventually get the best of me...it actually happens to during the downtime of the holiday season too...so, we'll see. This season though, I'm upgrading my speakers, so that will keep me busy.

Dominguez,

I know the FV15HP puts out around 98db at 12hz and probably more than that when placed in a room. With that said, do you think I should expect any reasonable output down to say 10hz?

^^ it's room dependence. In my room, my dual FVs reached 103db at 10hz without compression per the graph above. I am positive that they can have more than that if I can run a higher REW sweep. I got to find the graph with +5 MV sweep. Do I ever reach that level with my normal listening volume (-15db or -10db Max with subs 3-5db hot)? Probably not but it's always good to have the extra headroom when needed for the demo bass heavy session knowing my subs are capable of delivering the good

Nice. Try Godzilla (2014) for even more bass. Interstellar will be fantastic too.

I found the sweeps up to +5db. No compression. I hate to run sweep higher than +5mv cuz my house (not room) was shaking violently at +5.

I'd say generally speaking, I wouldn't expect it. However if you have a smallish room, it's definitely possible.

Hard for me to grasp this when my room is not outdoors, so I'd expect some kind of gain even if minute. What do I know though. :blush:

Well, you certainly have no signs of compression yet, so I would think you should have at least another 5 dB in the tank, although it is hard to say for certainty. If so, that would give you compression free output of 110 dB at 10 Hz, which is pretty impressive for a ported sub.
