I'm giving my 4 way OB full range dipole design for free under the "do whatever you want with this" licence. This one, from the thread with measurements and all:
You would need:
SB23MFCL45-4 8x
SB12NMNRX2-25-4 2x
SB23NBACS45-4 2x
SB26STCN-C000-4 4x
This is quite expensive.
The designs are in cm.
Holes are optional. Pun intended.
Sorry about croatian, I can translate it into english if it's not self explanatory enough. Also, green are wooden square bars, I opted to use 2 on sides instead of one in the middle.
Attached are the cad files.
This of course needs 16 channel amps, or less if you decide to run tweeters and subs in some shared config. Ofc then you'd need to redo the eq part to fix that.
For eq, it's as follows:
stereo signal input (pre) : -18db
stereo signal input (pre, eq) : param. eq, 3.7 db, 3300 hz, q 1.8; lr4 high pass, 13 Hz
tweeters = lr4 high pass, 4500 hz
high mid = lr4 high pass, 500 hz; lr4 low pass, 4500 hz; parametric eq, -7.7 db, 1323 hz, q 2.1
low mid = lr4 high pass, 100 hz; lr4 low pass, 500 hz; parametric low shelf, +18db ,172 hz, q 0.7; param. eq, -10db ,837 hz ,q 4
sub = lr4 low pass,100 hz; param. low shelf, +18db, 49 hz, q 0.7; param. eq, -6db, 232 hz, q 1.5; param. eq, -10db, 115 hz, q 4; param. eq, -15 db, 135 hz, q 1.5; param. eq,-16 db, 145 hz, q 1.5
If you are a madlad and actually decide to build something like this, feel free to ask for help. If you want to donate something to me for my work, give it to some charity/humanitarians/animal shelter nearby instead.
Enjoy.
Oh and also do double check if everything makes sense. Don't hold me responsible if my drawings are flawed in some way. I hope they aren't and probably should be ok, but still.
My next project will be headphones. Lots of them.
