Re: PK Sound
Tim,
The PK CX800, listed on their website, like most good touring subs, uses long throw 18" woofers with a large port area and a cabinet built to truck integers.
Nearly every manufacturer of subs has something similar, though many "big name" 3 letter manufacturers don't use as capable transducers filling the 18" holes.
They all look pretty much the same, other than minor cosmetic (and tuning) differences, because they are all constrained by the same demands.
To say that PK copied this sub design is akin to saying all automobiles copied Mercedes (Daimler) Benz because they use four wheels, a steering wheel and an internal combustion engine.
