Well currently my 2226 is in 175litres 33hz tuned with +6db boost at 35hz(inbuilt plate amp which i cant be bothered removing)Although it definately is loud enough,why not have more SPL headroom for pants flapping stuff with less resonant behaviour and more fidelity!

FINALLY the $$$ is coming through that i was missing - so im keen to cut MOST of the horn myself with skillsaw and a guide.

I can use woodglue/silicon sealant incase i get it slightly wrong;-)
Exterior will probably be just paint - I was thinking of a dark blue rather than boring black.I can always change it!

This way i save alot of money that wouldve been spent on the joiner! the only part he might do,is the throat baffle,because it costs heaps to rent a router.My horn only has the ONE critical 2 mitre angles on the baffle,he could do that one + wont cost much.

Ive been having a serious think about horns,and I can only have 1pi loading.

35hz i think is a good compromise,i wont notice a couple of hz,and it keeps the basshorn abit smaller.I dont want to build a 50hz horn then want a lower cutoff!!

Unfortunately alot of the horn volume is Vrc..But as an example 2 12"s on the same horn requires about the same.

All set to go! Just wondering about speaker terminal connector now..
