Horns
My system - in constant evolution since 20 years:
All horn-loaded (except the subs):
Peavey FH-1 bass horns with Klipsch K33 woofers (probably Eminence Kappa 15C in the near future)
EV SM120A mid horns with John Allen A55G drivers
Beyma CP25 tweeters
Focal / JM Lab SW900 Electra + SW38A active subs
Active crossover - analogue - 400Hz/24dB; soon is gonna be 60Hz 24dB as well
Passive 2nd order between mid and tweeter
global sensitivity 104dB/w
Fully modded Yamaha CX-1 preamplifier (all capacitors upgraded; all values <10uF lytics replaced with Wima MKS2)
Low power mini class D amps
Revox B226 used as drive; SMSL SU-8 DAC; VanDenHul integration ICs and QED speaker cables

When building the speaker cloth frame I wondered how to attach it effectively and easy, I read about 3d printers and saw they used magnetic ball joints, I figured that four ball joints would work, and it did it connects strong, might be an idea for other builders...
?forgot the pic..

After much planning, my system is now a 5.1. The source is a media PC with an Asus Xonar DG in. I have a TV, but I also have a big screen I can hang for a projector. That screen is about 3m diameter. My music system is packed away until my sound room is ready.
The front and surround speakers are built on Focal RSE-165 (car speakers), and the center is a 4" coaxial car speaker (MTX, quality is good enough). My woofer is an old 8" DVC which has about 50W per voice coil. The woofer isn't much to talk about, but it's surprisingly good when listening.
Surrounds on stands is temporary.
As for the amplifiers, it's a 4-channel, and a stereo amplifier for the center, both my own designs, about 65W for the 4-channel, and something like 100W on the center (way more than enough there).
I need better photos...

Okay, bad description, one ball in each corner of the speaker cabinet front, and four disc shaped neodynium magnets with a hole on speaker grill, the hole makes it easy to screw on, I attach pic, maybe it helps.

Properly aligned Neo magnets do the same (one buried under the veneer, the other imbedded in the grill frame), it is erie when you put the grill near and it snaps into place, but can be made to be completly invisible when the grill is removed.
