how does one estimate steps' spacing and their effect upon path from a given simulation expansion?
how does one best get an expansion generated by a program such as AJ-Horn into a real BLH? How do these type measure (and sound) vs BLH with less apparent lowpass function? are there plans for 20cm driver Olson-style BLH with bifurcated throat and single mouth? (~like Olson's 1937 patent aplication and RCA production speaker) - that might be a nice way Freddy RCA speaker (cabinet alone stripped of trim went for $26 on ebay) http://img133.imageshack.us/img133/276/646zl.jpg |
