Hi, my brand new NV215 arrived this afternoon, I have only tested it in my living room with my Thunderfunk. My first impression is that this cab really is designed for good old solid bass!....the tone is very thick and full as you would expect from 2 15", but there is also a great treble respons from the 6". What surprised me the most, is that the cab is very focused and tight sounding, probably due to the sealed design. There is the classic Bergantino trademark tone in the cab, a tone I would describe as a very sweet and just with a tad grind, I love this sound....I still haven't gigged with this cab so it is just my initial impresission...I will gig with it tomorrow and friday at a pretty big venue, really looking forward to it. Compared to my El Whappo, the NV215 sounds not as phat, open and BIG, but more "choked" and focused, I tend to like that sound, but I can see why others would prefer the EL Whappo....both excellent cabs.
