Modding the Zu Omen MKII

I own the Zu Omen Def mkii’s. I did the Radian Tweeter upgrade. Big improvement over the stock tweeter. 

Please tell me me more about how the sound changed from stiffening and adding the noise x to the cabinet.   And can you tell me how you stiffened the cabinet and the process to apply the noise x?

I added a solid 1x1 inch oak dowel right underneath the main element towards the back wall. Made it a snug fit, had to force it in place, and glued it in place with epoxy glue. 

Prior to this, I used about 1L of noise-x sound paint (for each speaker) in 3-4 layers all over the insides.

aldso adding new bolts with nuts torqued from the back side of the front plate, allowing for much higher torque.

made the cabinet «talk» vanish, and a much more dynamic sound all over. Good improvement in imaging as well!!

Hey zuangbro, 

Could you be a real pal and give me some specific links to the parts you've used? I'm really interested in these mods! And the things I'm wondering about: 
- resistor
- capacitors

I had trouble finding the correct ones. 

AND: have you done any more mods? I've also considered changing out the full range drivers.

effect placebo, if you won to hear difference , make change in one speaker , leave second one as this , and  try to listen difference.
The human sound memory is short
