cv is the one who started all this big SPL sub lunacy a while back so they know what they're doing....although over time the competitiopn has cought up and overtaken the cv - name me the last time they changed the specs or remodelled it????Hmmmm......
RE, BA, DD - they're streets ahead, although the CV1 will always be a classic. Bit like a a Shelby Cobra - old but still the respected daddy.
