Looks good Tony, should have good output in a box not much bigger than a single HD15, i like the idea of keeping the weight in the middle too these things do make a difference. 
I was confused with the term "push pull" too, surely if one is pushing and the other is pulling they will cancel each other out, should really be push push,  or push push pull pull, or isobaric...

Cheers mate, I was hoping someone would pick up on the reason for the offset :)

If you think about how the individual motors are working (when the pair is wired correctly i.e. technically out of phase) when the driver mounted with basket in the back chamber pushes the cone outward the other with basket out pulls its cone.

@ Tony
If these are plans you are otherwise willing to share I would happily help with drafting plans from your dxf-model for the good of SP's community. (No personal need for the plans as of yet)

Thank you for the offer but I do not want the plans published until they have been built and proven to meet their design targets.

At the moment I just do not have the time to commit to building a pair however I am happy to provide the plans that I have got to folks on the understanding that no plans get published until I am happy that the design performs well.

Yes, that makes perfect sense. Didn't mean to put any pressure on this matter.

Due to the amount of work at present had to put this on the back burner, however after the performance of the Q15 which has a similar alignment and uses the same drivers I will make sure that this is the next box I finish.

Quick update, these are being built by a fellow SP member who has kindly kept me up to date with the progress. Will post his images if he gives permission.
