Turn's out I have 38.9 L to remove volume wise from my chamber, which is a massive waste of space! 

If I was to fill the chamber I would need to fill this amount!

With the MR8XT roughly modelled to check for clearance. Planing on putting my the 1" comp in the horn mouth.

So I have been playing around with the horn a fair bit and it's certainly been challenging.

 Here's a few pictures of the different iterations of the cabinet, last one being most recent.

Still need to reduce the volume of the rear chamber to 17L.

When I increase the chamber size my frequency response graph become very logarithmic, with big peaks and dips. By keeping the chamber to 17l it allows me to have a lower HPF and higher LPF. 

As a plus it also seems to control the excursion.
