Thanks Mojo, I see how the 880 goes lower (which itself is weird, as it has the same 2 woofers), but I find it strange that the mid and high end doesn't behave like the M80, given the extra front-facing mid and tweeter.

And compared to the M80, the 880 low-end curve is extremely smooth, so I'm starting to wonder if they didn't show the HP curve.

For the first time I'm starting to feel the effects of an internet direct speaker company. Up to now I've only purchased bookshelves. I had no problem trying out one of those and sending it back if it didn't meet expectations. But shipping back towers, and especially towers with and amp and a DSP seems over the top (and probably expensive). It would really be nice about now to pop in and have a nice chat with a friendly dealer while he demos the two. Sigh.

Sorry, just a bout of nostalgia; I'm better now.
