Thanks Pit- what I want to do is marry a front horn/full range aluminium driver to a pro 15" woofer in a bass reflex enclosure- I also want to make the speakers attractive, ie sonus faber. I`m thinking if I made a thin vertical mouthed front horn to fit in a cabinet with slightly curved sides, the `wasted` volume can then be used for the bass driver, firing downwards at the bottom of the cabinet
The x/o wd be around 100-120 hz, but I am worried about the depth of the cabinet, ie how long wd a 100 hz horn have to be?
