Sorry for ignorance but whats custom Xover? :)
crossover which splits frequency between drivers.
The first thing I've noticed is dual driver. So acutually you have something closer to W4 than CK100 I believe.
It added texture to the bass and a bit more presence while maintaining the crisp highs of the CK100
Finally put my order in for a TF10x4 reshell.
Decided to save money and didn't go with any artwork or titanium faceplate - just went with the black translucent. Figured I can put little removable stickers on them if I get the urge for artwork.
Thanks to Matt and the team at UM Aus - they give absolutely brilliant service! Looking forward to receiving the final product.
I have to say that it's my first pair of customs so I don't have any comparison, but I've been listening to them for a few hours and they sound great. The finish and the quality of the shell seems also spot on.
