Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure

Moving from the V1 to the V2 eliminates (Or diminishes) the need for subwoofers? Quite an observation and outcome. I still believe that a lot of the V1-V2 differences are driven by specific system make-up and subsequent synergy results. It just seems that existing source, amplification, cabling etc can tilt driver preference in either direction. Then of course there is the large Spector of individual listener bias and taste. I still contend that both are superb options.

@mikeg Mike, good to know that the V2 driver is requiring less gain as break-in progresses.

I’m confused about your findings on the ’center fill’ / ’localization' to the individual speaker’. I don’t experience this in my system. Is there an explanation for why this may be happening with the V1s in your system? Thanks.

Congratulations on ’loving’ your V2s and the upsides they have resulted in.

Posting this for those who may be interested in utilizing Cube Audio drivers in a DIY setting. 

@realworldaudio  sometimes posts within the general forum. I find what he shares thoughtful and helpful.  He recently installed the Fc8 driver in his Voigt Pipe cabinets. He has a YouTube channel and this video covers his Fc8 driver impressions, immediately after the install.

@david_ten The V2s disappear better on all recordings than the V1s.  The extended bass and high frequencies result in better soundstaging and center fill.  It might be that I needed to move the V1s closer together than the V2s.

I haven't validated yet but I also think my Ayon Audio Odin SET tube based amp will better mate or bed in with the V2s.  

@mikeg   Thanks, Mike.  Also, great to hear that your Ayon SET may be the preferred pairing.
