hi julien
I too can recommend the DEQ 2496. I have done a write up of the 'playing' I have done with the DEQ and REW. It is in this forum, should be reasonably obvious which one it is when you scroll through.
I am using the DEQX permanently in my main system, so at the time I was killing two birds by using the DEQ ( and learning about it ) whilst simultaneously learning how to use REW. The point however, the forum you linked to also had an article on using the DEQ. In it, he stated that he only really used the DEQ to correct the room, because as he correctly pointed out in the upper frequencies the slightest movement of the microphone causes huge changes in the measurements, which would lead to wildly varying 'corrections' if you were to use the auto eq function in correcting the speakers.
If you are only going to use the DEQ to correct the room, as the fellow in the article did, then you'd be better off using the cheaper BFD's referenced on this site.
However, to use the DEQ to correct the speakers, this is how I suggest you do it. The theory and procedure follows that of the DEQX,which IS acknowledged as a world class system.
Use the auto eq function individually on the speakers, only down to say 100-150 hz. (it has a target curve function that allows you to set the limits). If you can, do the measurements outdoors, a cleaner signal will be gotten. Only go down to 150 or so, because you are one of the lucky ones who can use REW and you will be integrating the speakers into the room up to those frequencies anyway.
Now, this is the key, DON'T measure your speakers from the listening position, as is so often recommended. Measure them from about a distance of one metre ( or at whatever distance the drivers 'merge'). If you can't do them outdoors, maximixe the distance from any first reflection.
The idea we are trying to achieve is to approximate as best we can an anechoic condition, and the correct the raw or native response of the speaker. Put back into the room, integrate the bass and then we are away.
That method helps correct the speaker whilst avoiding the gross overcorrections that can occur in the higher frequencies as mentioned in the article. It is how the DEQX does it (albeit to much higher levels of accuracy than a 60 band graphic!) and is what seems to be an essential difference to the TacT approach ( NOT that I know much about it.)
Good luck, my earlier post explains a little more on the doingness, but I wanted to add the 'thinking' behind the above approach. In my earlier post I had graphs that were flat from the listening position, they are a bit misleading simply because as I said I was learning REW at the time, hence those measurments were done in the computer room, and so the listening position was coincidentally about one metre, which was the recommended distance above!! In my real room, the listening position is more 3.5-4 metres, so correcting the speakers from the listening position would have yielded vastly different and inferior results!
lots of love
