Thanks for all the feedback folks. To answer a few questions:

On a more serious note will these be available commercially Paul?
If they work really well, then it would be a good thing to offer others the chance to own a similar pair, but they'll have to perform well. I wont offer them if performance is anything short of excellent.

Looking good, Paul!

I'm going to add a small brass plate with the name of the loudspeaker at the back. trouble is, I haven't thought of a name yet....could this be an AoS competition I feel coming on?
Great idea - if you want, we could run with that

Thanks Marco, appreciated. I like the idea that after so much work, they deserve to be named! I'm currently looking into musical associations which haven't all been done before (like "Concerto" for example). If they work in harmony with the room, then "Reference Harmony" would be apt if a little twee!

Having a few tuning issues at the minute and now tempted to reduce the ports to a single port but have a few available for in room running at EBS 28Hz (F6 response) and 32 Hz F3 tuning. Seems the sensible way forward rather than use the twin ports which model quite peaky at the Alex Garner suggested tuning.
