Pros: SQ, sub-bass is amazing, detailed mids and highs, spacious soundstage
Cons: size and the fit is a bit strange at first
Not going into much detail because I've only heard from someone for a little while.
Bass and especially the sub-bass is outstanding I mean you can really feel the bass from the Kelton sub woofer.
Mids are clear and detailed and can be forward sounding at time as well, they're much better than the FXT90's mids imo.
Highs are smooth yet crisp and detailed also which gives the FXZ100 and balanced signature over all.
Presentation is very good with a spacious soundstage that's very wide and good imaging and separation as well.
I'll change the review and make it more in depth in a few weeks after I've had more time with the pair I'm getting but first impressions are very good.
