I have seen alot of posts about banpass boxes and horns not working in high spl areas. This is correct, the conventional ones will not work. I have been experimenting with ways to use the cab as part of the enclosure so this problem is eliminated. Many of my designs do not work, but the ones that do bring me closer to my ultimate goal. Special designs that are experimental are given out for free. I am also designing subwoofers(the PSI series) aimed at working best in these enviroments. I also design adjustable ported boxes for free due to the simplicity of the design. I am sure alot of people on this forum will agree. As for horns being to big, it is true but if you combine it with a ported/bandpass you get a louder sixth order bandpass that plays very flat from about30hz-80hz. And there is away to over come the high acoustic impedance the horn suffers from when stuck in a vehicle. So for all of the designers out there, experiment and try different things. Hands on experience is everything. You can only learn so much from books. Thanks.

I agree completely. However, from what I have done, the theory stays really close to the response throughout most of the range. I did not get the huge increase in efficiency that I was looking for, but I did gain a lot in efficiency. I seem to be going in a similar manner as I also have a design that incorporates some of the vehicle as part of the horn (developed from Bruce Edgar's Monolith horn). I plan on using that design exclusively next season after my choice of woofer has been finalized. And as for size, my horn is smaller than a comparable ABC box for my woofer.
