with Tapered Quarter-Wave Tubes, can they be done with multiple drivers per enclosure/transmission line?

if so how does this change the design brief?

thanks.

Hi, Yes

..if so how does this change the design brief?..

Brief: Not much but depends on how the drivers are mounted.

can you spare any time to give me some links or pointers for how to properly set up multiple drivers?

i have a single driver cabinet designed, and depending on how multiple drivers change the design parameters, i was just going to use 2 independent lines/cabinets stacked.

thanks.

is there software like winISD that models this type of enclosure easily? something i can use to see what the below looks like compared to the vented isobaric design winISD has suggested.

thanks.

Hi gafhenderson,

The entry point is probably Hornresp, and from there AkAbak. I don't know what the status of Martin King's mathcad design spreadsheets is, you may want to look for his website.
