Have you possibly considered satellites and subwoofers? Your midbass and tweeters could be made into some smaller stand mounted enclosures and the woofers could then have there own separate subwoofer enclosures.

no i havent but considerd i all ready have a home theatre with sattlites and a sub that would be my last option but what i was thinking that i have the box in a box like configuration. Have the woofer box and then have the midranges box inside it only downside is that i will have to calculate the 13.5 litres plus the 18 mm thickness of the MDF and add it to the total woofer box volume

My enclosures are not even as large as you intend yours to be. As it is, mine in their as yet unfinished state are almost too heavy to lift/move. I'm using 19mm MDF with full length internal bracing and a double thick front baffle.

When yours are finished I cannot imagine how much they will weigh!

Fissured Acoustical Ceiling Tile for moderate sound absorption/suppression inside the enclosure of the midrange frequencies.

The only way to become an "expert" is to make plenty of mistakes.
Anyway MDF is relatively inexpensive and mistakes are usually easy to fix or repair.

When I cut the large angles/bevels on the front corners I had to have someone help me to lift up and push the enclosures on the table saw.

I guess it's for keeping the distance...
Also for reference http://www.renatogiussani.it/the_forum_speaker_1.htm
which may be a step ahead when considering the system in room .
The woofer benefits from 'floor bounce' since it is a nearby reflecting surface it adds +3 dB ; omnidirectional source point given by the closed box design ,and total null of internal reflections with the prismatic geometry .
The mid-hi cabinet ... which has open back ,is placed at ear level's height ,and has almost no baffle ,making another point source .

Sorry to drag up an old thread. Did this project ever get completed?

I'm looking to use the peerless woofer in a sealed enclosure and am wondering how it turned out for you.
