Howard,
I can save you a bit of time.
Andrew (axiom's head electrical engineer) has stated that he doesn't use any auto room correction. I can not remember if this was in a post on the forum, or in an e-mail. For some reason i think this was in an e-mail.
As far as the LFR's go. I went through the audyssey setup, i did this by unplugging the rear drivers while running audyssey. However, i wound up doing a considerable amount of manual manipulation as well as removing some of the audyssey settings, like the EQ.. I'm using a Marantz AV 8801, which has Audyssey MultEQXT32.

Dakkon, I really appreciate your help on the subject again. Your answer explain things perfectly. This is my understanding. Conventional method of room correction may not work properly with omni directional speakers like LFR. That's why Axiom designed a three channel DSP (L,R,C) to make sure that the frequency response of center channel correspond with LFR nicely.
Since my AV receiver which uses multEQXT32 as well, I will get DSP3 and experiment with XT32 like you did and if I am not satisfy with the end result I can always reply on DSP3 to dial-in the center speaker.

Howard, Just to be clear, the DSP is not a user-adjustable unit.

There is one user accessible adjustment on the DSP which you can use if you need to be fairly close to the rear wall.

To be clear, if you get the DSP with centre channel you are spending extra money to make the frequency response for the centre extra flat. That is as measured with Axiom's precise instruments and presumably in their anechoic chamber. If you also use room correction in your receiver it will be making corrections before input to the LFR DSP but after the results of the speaker corrections built in to the Axiom DSP. In short it just seems like over processing at best and potentially may make things worse instead of better.

And...if I'm not mistaken the DSP is upgradeable after the initial purchase.
