Are the drivers going to be in phase or push-pull?
proposed box designs
Hi all. I'd like your thoughts on these two LLT box designs that I'm interested in making. They are variations of roughly a 19" x 30" x 49" box optimized by WiniSD (WiniSD pro no worky on Vista ).
- 457L
- tuned to 16Hz (two 6" circular ports ~33" long)
- vent mach 0.07
- dual 15" (Tempest x2)
- 3/4 " ply
- internal bracing not figured out yet.
I'm more concerned about any negative effects the placement of the ports would have on performance (particularly in the lower profile box....port on two opposite faces). Initially I wanted to do a single long slot port, but I read that it must be done precisely to get good results (surface area aspect ratio 3:1............complicated). Any thoughts will be much apprecieated. If dual 15" is too much, or there would be no added benefit, feel free to tell me so. I plan on doing a simulation with card board and pvc tubeThanks again.
