Modding the Zu Omen MKII

Hi all

I am a bit courious as to if anyone else went down the DIY mod path with their Omens?

What are your experiences?

On my mod list (so far)
- New Double xover capacitators
- Adding a parallell resistor to the tweeter
- Stiffening of the cabinet
- Painting the insides with noise-x
- New internal cabeling
- New bolts and fastenings for main elements.

They now sound fantastic! And play in a different league!

And probably more mods to come! ;-)

These values are a result of scaling compared to what I know Zu use to match the 850’s with the 103nd drivers, accounting for the differences 260drivers.

note; these values will work for the 8Ohm 475-be radians.

if you go for the 16ohm Radian 475 version, different values will apply...

Also, there are plenty of L-PAD calculators available online.

They will however give you other values than what I proposed above...

Alright. Thank you very much!

lastly, this bracket to make the tweeters fit, where can I get some?

did you explore switching out the full range driver?

I got the bracket of a local supplier, but you can probably buy it together with your 475’s from the same supplier. Just make sure it fits the threads on the original Zu lens. 

The original eminence asd1001 driver has 1 3/8in (18ext.) threads.

did not change the main drivers as I am very happy with the sound right now...
