close transmission lines

theChris · 1st January 2006, 02:10 AM

i've been working on a box design for a dayton reference 7" woofer and a 3" tang band mid/tweeter. currently, i plan to use these as computer speakers, so they will be fairly close to me, and not directly faceing me. both speakers are phase plug designs.

in anycase, i've heard that TL speakers typically have the speaker near the top and the port near the bottom. I can do this with and it models so far pretty well, but i wonder if it is a good idea for the speakers placed so close to me?

any opinions?

Sometimes the driver models better in the middle or lower part of the baffle. The port can be anywhere, depends on how the internal baffles are directing the sound waves. I have two TL's, one has a port on the bottom front the other on the rear at the top.

I don't think it'll hurt, but if the crossover isn't designed just right you might hear 2 sources of sound. The 2 drivers should blend and you shouldn't be able to detect which driver is reproducing what to the music.

Are you using the 3" Bamboo driver, and if so, could I possibly see the crossover schematic?

BTW, you are at SIUE? I'm up at Bradley.
