Mcintosh MEN220

[mb225]

Has anyone ever used (or demoed) a Mcintosh MEN 220 “Room Perfect” system? I have been reading a lot about adding a subwoofer to a system and I found this really interesting article:

Looks like the MEN220 will split the signal and send everything below a specific frequency to the sub and everything else to your mains (goes inline before amp). Or you can use it for true bi-amping. Plus it has a room correction system built in. I was wondering if anyone had any experience using it? Is it a valuable addition to a 2-channel system?

What is it you planned to do with it?

Just read this information online:

Anyway, there are definite advantages to speaker and room correction.

I've been considering this product, to use as a crossover for my 3 way speaker build.

There is the DEQX HDP-3 for $3950 and the HDP-Express for $1950. They don't really tell what the differences between the two are though. They both have the same functions.

My plan is to add it to a 2-channel system and use the crossover to send everything above 80 Hz to the mains and everything below 80 Hz to subs. I'm pretty confident it can do that. My questions are:
1) Has anyone used the room perfect mode? Does it do anything? Is it worth the cost?
2) Can it delay the signal to the hi/low pass to get everything lined up in phase? Does it calculate phase automatically (using the mic) or do you need to do it manually?

The other option I was looking at was the DEQX but as you stated, it's $4k for the one with room correction and the McIntosh is $4,500. I just wanted to see if anyone uses the MEN220 or heard one. If so, what did you think?
