Sub equalization: upgrading from REW?

[josko]

I have a Behringer BFD and use REW to program its' parametric EQ. The resulting FR curve looks 'reasonably' flat, but I wonder how much the field has advanced, whether it makes sense to try to upgrade from REW and, for instance, try to get a larger equalized area (compared to the single point that REW does).
Are there other EQ systems that would give a noticable upgrade?
I have a UMC-1 with EmoQ, but have so far not used it. Also, my sub (SVS SB13) has two PEQ's, which I've also left alone.

IMHO, your upgrade path should look like this,

1. Add second sub, run in dual-mono mode using BFD (stacked/ opposing walls/ opposing corners of same wall/etc.)
2. Add 2nd BFD or upgrade BFD to DCX2496 and run stereo subs
3. Add 2 subs, use DCX2496 to run dual stereo subs

I don't think there is much to be gained by adding an automated room correction device if you are already competent at doing it manually. Last but not the least, if adding a second sub is not an option, look into room treatments.
