They all sound great for daily use as well as put up numbers! We only have the VVX-10 D4 and VVX-8 D2s in stock from this line at the moment!
My 10s get pretty **** loud for being on 400 watts, flexes my car a bit and sounds great doing it. Would definitely recommend their subs to anyone who's looking to get loud and low, while sounding good and also while not spending a lot.
I'll have a review posted when I have my new amp powering them.
I will vouch for these subs, I know most people hate the term SQL but these really do sum it up. They have a very accurate impact and are extremely musical, but they did not lie when they said they were built to be low end monsters. I would say one of, if not the best, subwoofer in their price range.
Are you still offering the two sub and custom box deal? I shot you an email earlier. Hit me up. I'm really interested in that deal.
