    Sorry for the off-topic outburst. I couldn't contain myself!
    Sweet!
    Which finish did you get?

    ************************************************** ***************
    Sierra Mini Tower idea (I know I know) PART 2 - Understanding MMT vs MTM
    ************************************************** ***************

    I'm starting this thread afresh! Why? To re-focus my thoughts. I am trying to learn (from this site and others) the pros and cons of MTM and MMT configurations.

    MTM:

    Pro: More output, efficiency, and sensitivity.
    Pro: Symmetrical lobes/nulls. (may be managed easier in design phase?)
    Pro: Woofers always in phase with each other (on tweeter axis)
    Pro: "Controlled directivity". (depends on the person)
    Con: "Controlled directivity". (depends on the person)
    Con: Possible comb filtering (requires a lower crossover to manage this? To have wider vertical dispersion?)


    MMT:

    Pro: More output, efficiency, and sensitivity.
    Pro: A fairly short tower (tweeter on top).
    Con: Woofers only in phase with each other on the tweeter axis if you are at a "planned" distance?
    Con: More challenging to deal with 2 distinct sets of lobes/nulls due to path length differences between tweeter and woofers?




    Alright. I'm just interested in learning the pros and cons here. Whenever ya'll get time. Thanks!! (I'm still reading on other sites too)

    I'm leaning toward "MTM" being overall better due to what appears to be more midrange clarity on the tweeter axis. It hasn't escaped my attention that a MTWW design appears to be a combination of both configurations! MTW (mid and woofer always in phase on tweeter axis). Then you have TWW on bottom. So, at what distance from the tweeter is the tweeter and lower woofer in phase? (I'm really getting out of my depth here guys, but I'm having fun.)

    Any thoughts on this? (Dave, I love your technical input, but I'm in no hurry. Go on vacation!! Cuz, you da man. )

    The hardest part! Love that finish - same as I have.

    I know! Yeah, black goes with everything. Piano black makes me finger print paranoid. Matte black isn't my thing. Satin sounds nice! To each his own! I got a buddy at work that's gonna come listen to them. I'm thinking he might just get some Ascends too when he hears them.

    Okay, well now I'm a little embarrassed. I've been reading previous posts that Dave has answered and I now realize that he answers these kinds of questions over and over again. It must be exhausting! Kinda feel bad for asking yet another "why not do this?" lol

    Dave, you da man.

    I appreciate all that you do for others. Good sound to you, too. I KNOW that the Sierra-2EX will be reality-warping in this small apartment. (Dr. Evil laughs along with mini me)

    Please disregard my "mini tower" idea. You keep doing what you do!!
