 I wonder if the internal size of the cylinder is larger then the box design, and if it is, then it should have some output advatage over the box design. |
The PB13-Ultra has more effective enclosure volume and is tuned slightly deeper. It's a slightly better performer at the very deepest frequencies for these reasons, but subjectively the two subs sound/feel similar on the vast majority of program material.
Of course the cylinder has a big advantage in footprint and weight; in this respect we feel the PC13U is one of our best subwoofers ever when it comes to balancing overall size/weight, footprint, and performance. I'm sure anyone who hears a new PC13U in action will agree - it's a fabulous performer and an obvious improvement/upgrade over the PC12-Ultra it replaces.
