Hi, I've been reading lots about dipoles, hframes etc. I like the W Frame that's listed on Linwwitz site (Phoenix). He uses 2x 12" woofers.
I have on hand 4 Eminence Eminator 2515, I've been considering various alignments for a long time; but I finally have wood now too, so I'm close to cutting now.
These drivers appear to me to have Qts, Fs, and Le that would be appropriate for a dipole, so I may give it a try.
Here's my questions. Please refer to attached pic. The pic is the Linqwitz "plan". I want to be able to use 15" woofers.
Can I simply increase the dimension of panel "D" to something like 17" x 19" to accommodate 15" driver?
Do I understand correct that the "tuning" of the box is mostly determined by the length of panel "A"?
My theorie is that if I leave panel A at 19", that this determines the length of separation between the front wave and back wave. Also it controls the length of the 1/4 wave inside the box. Therefore, if I don't change that length, it should work.
am I on the right track, or should I scale the entire box larger? I have not found a w-frame sim or other design tool yet.
Looking forward to replies.
