mt121 new build

I like the design and sound of the mt121 and i am planning on building two myself, i have already made up one prototype flare unit out of some 12mm ply i had lying around, it was not as bad to build as i first thought. It was assembled in about 2 hours (cut and built), now all i need is to get some quality ply and build two of them. I aim to start my build next week as i am off work for a week, just hope the weather is good. One question for you ? if any one can answer it. If i was to change/alter the design of the mt121 the original baffle cut out is 220x164, if iwas to keep the volume the same but change the cut out to an octagon style cut out how would this change the sound produced!?. I would keep the rest of the dimentions the same but i am looking at the middle part of the flar being octagon shaped as well. Then the mouth of the flar square whats your thoughts!.

no just saw some plans simular and i wondered what it would sound like!. Im going to be building the mt121 as designed my rog they sound and look great. I would try and have a go with hornresp to see the responses but im still learning it and wouldnt know where to start!. 

Reading other post's i got the impression the mt was very hard to build and the plans where slightly out, so i marked out all the flare sections on some stiff card cut them out and taped them all together. After a few minor angle changes used the card as a template and cut out the ply, it all went together perfect first time. The ply i used for my dummy run is real bad quality so im going to pick up some quality ply tomorow from my local wood yard, and get building this week. My original question is just me being curious about how it would sound.

Awesome stuff there.
I like it, keep up the good work, also what are you loading these with?

what sort of stuff do you play through these? I would serously recomend trying a 6.5" and 1" as this may sound stupidly clear and defined.
if not, yeah you would just have a little bit more head room in the his, alot of people have similar setups some even with bullets too, which is nice!
