series bandpass & series bandpass-horn?mutual load such as scoop & "tapped-style" horn where driver is located at throat and mouth?
BLH cases like BIB where the pipe comes to a point and driver is specified some distance from that start?
Follow Ups:
perplexing trying to sim a little Fostex 166E "BIB" pipe horn to match up with results shown using Martin King's worksheetssim at Zilla's BIB pages
AJ simulation with pointed pipe and driver ~27.5" down from small end
traces are half-space, floor + wall & corner
simulation (red trace) with different description of horn and throat area set to = cone area - Red trace with driver at "0" kinda kluged a correlation but didn't seem to fit AJ's rules (?)
how does one link a vented rear chamber into a front chamber for series bandpass?
"how does one link a vented rear chamber into a front chamber for series bandpass? "
I don't know, but in my experience if the horn's long enough to go below 100 Hz it won't work anyway, the air mass of the horn defines system resonance and you can't tune the rear chamber.
yea - but its a hassle not to know how to construct a simple series bandpass model and AJ" manual illutrates parallel BP- - guess theres always the late Bob Bullock's BPBOXMODEL but due to windoze XP screenshots don't seem possible... thanks MS!
