I would work with the natural response of your sub and focus on achieving a good response/sound from 30Hz upwards. If you have the funds then consider experimenting with some form of tactile transducer for your bed, i.e. I would not expend excursion for the ULF at those listening levels.

should I also consider a flat response like this?

There are 2 things there. One is considering a "flat" response as part of determining what sort of response shape *you* like, the other is whether a rule flat response like that makes sense irrespective of how flat your target curve is. The former you should definitely consider (though I wouldn't start there myself), the latter I would say is a bad idea, work with your sub/room not against it. You're trying to finesse it into a pleasant shape not bludgeon it to death

Remember that your other channels are crossed to the lfe and so when playing real content through your lcr the bass will add up and create the house curve. To test this out do a sweep of channel 4 (lfe) and then another sweep except use channel 1 (Left) AND channel 2 (Right) by picking the second channel to the right of the first in rew. Don't change the volume on your receiver or anything between tests. The second test includes the lfe and any content that is below the crossover point of your main speakers.

So, to flatten your subs responce, I'd use the lfe measurement, (take several and average them) set the speaker type to None, let it auto choose the target level (this ensures you don't bring down the overall level with your filters, just the areas that need it), and set the boost and overall boost to 0 and flatness target to 1db. Enter the filters in your eq, done.

Now at low volume this is not going to sound great, at reference it will sound awesome. Why? Our ears follow a fltcher Munson type curve where we need more bass boost at lower volumes. I've found that in my setup I can achieve this in two ways. My old avr with Audyssey ( I don't use Audyssey BTW) has a "Dynamic EQ" setting. It's not adjustable, but it does add bass boost at low volume and decreases the boost as you go louder towards reference. My iNuke has a DEQ setting which can do the same thing, it's totally tweakable. Either one makes for an awesome, full sounding system that won't clip ar high volumes, etc.

This is what I've determined so far to be the best setup for me.

So, those 6 filters with 1dB tolerance would be bludgeoning it to death? Would aiming for 3 filters and 3dB tolerance sound better? Or at least put less strain on sub amp and driver?

you keep asking what sounds better but only you can decide that, trust your ears to tell you what works for you

you are using up 8-10dB to bring everything down to that level, if you have the headroom to do so then not an issue otherwise you'll just compress under load.

Just to clarify, you're saying that the max output from my sub would be 8-10dB lower than without any EQ?

If so, am I correct to assume my modest listening levels of MV: -30 and under will prevent this from being a problem?

Hi everyone,

Thanks for your help so far. For other mac users here's what I've done to get this working:

1. Used Audio MIDI Setup to create an aggregate device with HDMI out. In order to keep my sub in play I routed the Left Front speaker as channel 3 (center) and the right front as right front. I then unplugged the right front speaker in order to isolate to just the center channel plus the sub.

2. In Audio MIDI Setup I adjusted the gain on the UMIK-1. I compared the REW SPL Meter to an external SPL meter, settling on a db setting of 18 for both channels in Audio MIDI Setup. This gave me the closest match between the meters.

I then pulled a measurement for the center plus sub:

I've got the center crossed over at 60Hz, I'm wondering what might be possible to do about that dips at 200Hz and 250Hz. Also, the average (estimated) spl below 150Hz seems about 10db higher than the rest of the spectrum.

The waterfall shows a lot of ringing. I've already got 6 GIK bass traps in the room (from some earlier efforts to try and tame things):

That way you'll measure a higher sub level because bass management will still route low frequencies of R to the sub.

I have a dip in the 200-300Hz range that is caused by the two chairs I have for listeners (the MLP and a second chair). I verified that the chairs are causing the dip by removing them and re-measuring. So, unless I want to listen to my system standing up, I have resigned myself to living with the dips. I don't perceive any bad effects, though, so I am not overly concerned. You might want to test to see if furniture is causing the dips as well.

As for taming the bass ringing, more traps, and perhaps more effective traps, might be the answer.

Page 60 where the first measurement instructions are have you using L+R+Sub, and many posts previously in this thread reference taking measurements with the sub present.

That's different from what you're doing. With bass management engaged low frequencies of L and R are routed to the sub. If you disconnect L or R low frequencies of L AND R are still present in the sub output.

Revised parameter waterfall and spectrogram attached.

Thanks for the input Markus, I understand now what you mean about the low frequency from the left still being routed through the sub. I'm wondering then how to get accurate measurements with the sub mixed in. It seems that I'd have to pull L+R+sub all together. As long as the receiver thinks it can play on a channel it will do so, so I'd have to do something like tell the receiver it had no rear surrounds and then route one of the channels in the aggregate device to that unused channel.

That looks better.

Your ringing isn't too bad, but if you look at the ridges in the waterfall or the red "blobs" on the spectrogram, you can tell that your bass response is kind of all over the place. You want it to look more like the one below where the sub is generating almost the same amount of energy throughout it's range.

You should take separate measurements of L+sub, R+sub, CC+sub and L+R+sub. If your system is used mostly for movies, the most important being CC+sub.

Wonder what the plumes on the underside of my spectrogram mean? I don't see the same on Alan's.

I get the same thing before the 0ms point on my spectrogram, and it looks like background noise before the sound starts. But I know my room is quiet. It also continues to 1000ms.

Hell Jerry, if you don't know, who does?!

FYI, that isn't my spectrogram, I stole it from another thread.

Ok, new to the REW game. I want to go ahead and buy a mic so I can start fooling with it. Need it to work for both my home system and car system as I will be running dsp in both.
What should I get? My home system will have two FTW-21s and a pair of 15s or 18s

You should get Jerry's guide:
Simplified REW Setup and Use (USB Mic & HDMI Connection) Including Measurement Techniques and How To Interpret Graphs
If you're going out to the car, obviously you'll need to run the program on a notebook. A refurb PC with an old version of Windows will be more than adequate.
You should read Jerry's guide.
Welcome aboard.

I have experimented with using REW to tweak my vehicle's audio system. Using a laptop and connecting the headphone out jack to the vehicle's AUX In port, I was able to output REW test tones over the car's audio system. Positioning the USB mic at ear level in the driver's seat was a challenge involving a tripod and a lot of masking tape. Not perfect, but workable. The major issue I encountered was that the vehicle's equalizer didn't have controls that affected the overall audio response very well. I did the best I could, but in the end I questioned whether using REW was worth the effort.

My car system runs the RF 3Sixty.3
8ch full dsp. Individual 31band Eq on every channel. Time alignment. Crossovers.... believe me that it will take full advantage of rew. It's how 99% of the users tweak their systems. I will be running fully active. 3-way front stage and two subs.
My home system will run a mini dsp 2x4.
