LENGTH of front chamber



Hey everyone!

Am thinking of using the Eighteen Sound 8M400 driver in a tractrix midrange horn, it models VERY well in hornresp. I was told that the LENGTH of the front chamber can make a difference, no matter what hornresp says. 1cm is too short according to this person for 6-8" drivers :P is this correct? I have no idea, would 2cm length be ok?

Thanks!
Adrian
