So I've had some eminence Beta 10's and Selium D220 Ti's for a couple months now with the intention of using them as surrounds. I just moved 3 weeks ago and am just about ready to start on the new theatre so figured I had better get these speakers built. I picked up some Birch and started on the boxes this week. They are all glued together, hopefully this weekend I'll be able to veneer them and router the speaker cutout. I didn’t take to many pictures of the build itself but I have a few pictures I can attach. If the pictures worked, you'll be able to tell my build was very much inspired by Erich's surround kit as well as the JTR slant 8.
Originally I had planned on using a MiniDSP as an active crossover on these. Now I'm realizing the pain it will be to dedicate 4 channels to 2 speakers as well as having to find some sort of amplifier for them. I have read a few builds with this speaker combo and have a schematic for the crossover but I really don’t know how to interpret it. It is a XO designed by Zilch and is the same one used in this build:
Budget Eminence Coaxial surround build!!!
I think I have figured most of it out and have it all in my PE shopping cart. I'm looking for someone's input on whether or not I'm ordering the right stuff and also what I'm missing.
1- Dayton Audio DNR-30 30 Ohm 10W Precision Audio Grade Resistor
Part # 004-30
1- Dayton Audio DNR-16 16 Ohm 10W Precision Audio Grade Resistor
Part # 004-16
1- Dayton Audio DMPC-12 12uF 250V Polypropylene Capacitor
Part # 027-430
1- Dayton Audio DMPC-4.7 4.7uF 250V Polypropylene Capacitor
Part # 027-422
1- Dayton Audio DMPC-0.47 0.47uF 250V Polypropylene Capacitor

Right now I have 4 different inductors in my cart. One of each of the required spec but one set are the higher quality perfect lay inductors. Are the higher quality ones worth the extra cost?
1- ERSE 1.5mH 14 AWG Perfect Layer Inductor Crossover Coil
Part # 266-360
1- ERSE 0.60mH 18 AWG Perfect Layer Inductor Crossover Coil
Part # 266-818
1- Jantzen 1.5mH 15 AWG Air Core Inductor Crossover Coil
Part # 255-426
1- Jantzen 0.60mH 15 AWG Air Core Inductor Crossover Coil
Part # 255-412
I also plan to pad down the Selenium but I can do that after I have the crossover figured out.
These speakers will be powered with my Denon 4311ci and will be used as the rears with my JTR Triple 12's up front in a 5.2 setup.
I have tried attaching the schematic as well as 2 pictures of my build. I don’t know if they will work or not...
If not, here is the link to the XO schematic.
