You should try to keep the c-to-c to less than 1/4 to 1/3 wavelength. However, its not the end of the world if you cannot do it. The vertical lobe will be symmetrical horizontally if you put the measurement mic halfway between the two drivers you are measuring and get good phase overlap between them through the crossover region. This way the drivers will sum in-phase at all points near the crossover, and as you move up or down vertically, the phase response from each driver will change resulting in a cancellation, i.e., lobing.

Was that simmed in TL or sections TL worksheet. ONe of the things MArtin talked about in his TL Tqwt paper was how folding affected the response of the enclosure vs tall and straight.

So,
Just simmed similar enclosure and noticed something interesting. THe improvement in your response over my 1.5 version has more to do with driver location than line length. We have virtually identical responses when compared to my mid placed driver version

@Wayne

I now have another member who wants results, so it look like it is going to happen. I am officially under peer pressure now. One will be a monoblock, the other will be on single side of current V2 version.

What does the "a" stand for?
