Most normal HT fanatic upgrade by buying new gear, but us DIYers upgrade by building new stuff! A year ago, I built a mammoth center channel speaker (28"x10"x14") with drivers more suited to my old speakers (they were a 10 year old DIY project as well). Now that I have my new fronts and rear speakers "done" (all the gory details are in my signature links), I've decide to rebuild a center channel box, and will be using the same tweeter (Morel MDT30)and midwoofers (Peerless HDS850439) from my now current speaker setup, and will be incorporating the Morel MDM-55 midrange into the mix. I haven't heard too many negatives for the MDM-55 midrange (though it's a bit pricey, but I figure that the center channel is the vocal anchor to a good HT setup, so money isn't as big an issue as before), and its form factor will allow me to shave over an inch off the height of the enclosure, and I think I'll be able to shave 3" off the width of the front baffle as well, so it should be a smaller enclosure once I'm done. I'm shooting for a final box dimension of 25"x8.5"x13" if I can squeeze everything into it and still hit the performance goals. It's be a non-conventional 3-way setup, with the tweeter and midrange in a vertical arrangement and flanked by the 2 midwoofers on either side (just like my current center channel speaker, but I'll try to get the drivers closer together on this new project). I thought about retrofitting my current center channel, but it'd be a shame to hack it up, plus I get to make the box smaller by building a new box.
