I ordered a pair as well (the base model DW6).
I’ve owned the Zu Omen MK II for about 5 years give or take. And it’s a truly awesome speaker. I did the same thing you did a bought them blind. I had begun getting frustrated demoing speakers from a local vendor (vendor was great but the expensive list of speakers I marched through meh). Zu speakers are not always praised for top end clarity, or super detailed hifi sound (at least their most affordable models) but what some may argue they lack there (I think they sound great top to bottom) they more than make up with their energetic dynamic and “live” presentation. Be prepared for some hate. People who dislike them can be a judgmental bunch. I’ve happily used mine without a subwoofer and I enjoy bass especially with hip hop and the like. These are supposed to improve in every one of these new areas with the updated cabinet and port loading design. And I have trouble finding fault with the MkII. I’ve used them with cheap equipment and very expensive equipment. And while they will reward you when running with well matched gear, they’ll sing being driven by just about anything.
Zu has a very awesome but polarizing approach and sound. Usually the people who enjoy them fall in love. I’ve trialed a good deal of other audiophile gear from source to amp. Zu speakers help you forget about all that mess and concentrate one what’s really important…enjoying the music.
I hope you’re as happy with your purchase as I know I will be.
