They are quite a bit taller at 47.5" but the same width so we will include the outriggers.

Doh, that means my better half may notice something different... Do you have a reality distortion field adapter to make them appear as M80s?
Man, I don't think I will be able to pull this off as I just did a big upgrade a few weeks ago. I don't think my wife is buying my story that "no honey, nothing's changed in the TV stand". I upgraded my VP150 to a 180. Also swapped the rears for M3s but she didn't notice that.
For every expert, there is an equal and opposite expert.

So, are the M100's basically the front side of the LFR1100?
Do you have four of them hanging in the boathouse, yet?

Yes, Brent and I were discussing what can be done for existing M80 owners to take advantage of this upgrade and we will be finalizing that in the next few days. I'm guessing it may require a crossover change with and if the M80's can feel the love too  I just got mine too ;(

Probably just some added stuffing to make the box volume appear to be different

I'm guessing it may require a crossover change with and if the M80's can feel the love too I just got mine too ;( I dont think the m80's would need a new crossover. the main reason the LFR's will need new software is due to the level of control the DSP has. A crossover network is a much simpler electrical device. the new woofers would probably have a similar high end as the current ones, and mainly play lower. thus, the current crossover "should" work perfectly fine. Ian and Andrew would be able to better speak to this though.

Ian, the Thiele-Small parameters on the new woofers would be of interest, especially the max excursion and Fs.

Hmm.... FS = 45.4 Hz. Nice excursion!
Bookshelf with significantly better bass response than the M3?

Back of napkin design: 1.5 cf cabinet, tuned to 30Hz gives a -3db point of 27 Hz. Good output to 500hZ. 100w applied gets you 104db output @ 1m across much of the range. Yum!!
