Default Tapered Quarter-Wave Tube Tapered Quarter-Wave Tube

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

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.

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.

Regards,
