My 18" horn, Invader Bin

We have built a prototype and made a test with http://www.faitalpro.com/en/products/LF_Loudspeakers/product_details/index.php?id=201070135 - this driver .... there is a heat issue. It is 1200w driver but we are planing on using 1600w.

More test will be made with mods. I want to use it up to 150hz cut.

Anyone simmed these with the letterbox throat?? If so what size is it? Gonna build some but think I would struggle with the half moon config

Have this been simmed the "correct" new way?
I'm still considering to build 24 for my 18-1500!
Most often I use 6 per side, as the sim above suggests it's nice to have a lot of these!
I won't afford it this winter, but perhaps next winter.
I'd probably do a ported version.

I'm a bit confused about the simming:
1. It appears to take some of the air in front of the horn into account,
2. Where does S1 start and what's the front chamber? I guess the horn won't start until past the cone?
3. I've seen one sim that was simply "tra", perhaps the horn is designed from tractrix output data from hornresp? Others are con sections.

Thanks in advance for further clarification.

Don't go with any of them

Kid , ever heard, owned Invaders?, if so same as above why not sed drivers..?

Looking as though v1000 it will be then unless anyone can suggest alternatives to the ones in the previous post. I looking around a max of £300 per driver.
