NICE! What about other drivers like Faital Pro neo's??? Any plans yet for DIY peeps??? Thanks!

Thanks djlivex!

I have simulated with an EighteenSound 15W700. It simulates exactly as an 2226, but it has 1 mm shorter xmax. Xmax is the limiting factor of this box.

Any driver with close enough parameters will do well. Just pm me with a particular driver and I will simulate it.

Excellent result.
Can you post HR export or input screen, I'd like to try a few drivers in this.

Thanks Dan

I designed it for corner use. The previous simulation was done in 2 pi is just to be able to compare with measurement. It will go down to 30 in a corner.

I am using it to 80 hz:

Very nice build !!!

Thanks Jer!

It gets even better with more cabs (using the simple inacurate multiple cabs in hornresp):

Nice Work ! I really like your microphone stand ! Should I assume that this design will work just as well for the JBL 2226J (16 ohm version). What is the dimension of the horn. I have four 2226J that is looking for a project. This might be it.

djlivex asked for a simulation with Faital Pro 15FH500

It is very close to JBL 2226 (compared in graph):

I also did a simulation of 4 cabs in half space using Faital Pro 15FH500 powered by 1,3 kW:
