AEIOU, planet 10, and squeak thanks for your posts. Though I am willing to consider many designs I don't actually have the knowledge to create one from scratch so I am bound to use designs other have taken the time to create and trouble shoot. Perhaps I should be less concerned with looks and find a proven design that appeals to me. I will post what I wanted to build originally before I started this thread once I draw it up in photoshop. Perhaps there is a member who would find it interesting and could model it to see if it is worth pursuing. THen again maybe modeling is a difficult process and I am asking too much. Be back with an image of some sort soon....

Without being sure, you could probably find a ML-TQWT design that fits your needs and drive specs pretty closely. And pretty closely is good enough in most cases, because driver differences, room placement and stuffing will play a bigger part in sound than tight measure tolerances.

I just looked at the pencil plans for the alpair 10 and 10.2 and zman01's point becomes clear, that being, "the plans are for Alpair 10, and using Alpair 10.2 might need slightly different considerations". The cabinet volume for the 10.2 is 4153.3 cubic inches. Even taking out the battens to allow the back to be removed it is 4104.5 cubic inches. The pencil plans for the alpair 10 has an internal volume of 2999.875 cubic inches. That's approximately an 1153 cubic inch difference.

Checking your math:
Pencil 10,2 extends the depth by 43mm to yield an extra 7.83 litres on the originals 59.88 litres. 13% increase in volume

(4153.3-2999.9)/2999.9 =38.4%
