People have been interested in building a ported (fullrange) version of the MTM that Tibor built a couple of years ago.
For those that don't remember, Tibor's sealed design speaker, here's a pic.
To date the 'best' ported version using the Hi-Vi drivers is Jon's M8a-T&A
Just so people don't get confused, either cabinet design will work for the MTM. The faceted design is optimal, but the standard flat front works VERY well.
Later today Jon's going to post box and port sizes modeled in Unibox.
The only 'fixed' cabinet dimensions are having a 12" wide front baffle, and maintaining the fixed front baffle spacing between the MTM drivers. This means that only the height and depth should be adjusted to create the required volume for good bass response.
Here are the block diagrams of the MTM crossovers.
Here's a link the Pete Mazz's ported version of this design..
