Opinions needed

This is pretty meaningless until you share what aspects of sound reproduction and and speaker performance are most important to you. 

A friend owns the Cube speaker and I am saving up to purchase it.  I am sure all the speakers on your list are very nice but this is a single driver done right.

Hi 10ht, You really need to tell us what amp your planning on using?
Thanks, TISH

Hi 10ht,
I agree with those who say that more specific information (room size, preferred listeningvolume level, amplifier etc.) will likely result in more meaningful recommendations. What sonic characteristics do you most value? Given you enjoy jazz (so do I) the Cube Audio Nenuphar is definitely a prime candidate. From what I have learned from a friend/Gon member who owns them (10" model) they are spectacularly good sounding speakers. Amplifier compatibility will vary greatly amongst your list of speakers.

Thank you all for your replies.

My room is 9,2m x 4,8m
Unfortunately the speakers need to be placed very close to the back and side walls (~20-30cm from back wall and ~40cm from side walls)

Regarding amplification I can use Simaudio Moon 860A, 2x Burmester 911 MKIII or Channel Islands D200MKII

Best regards
