Yep ... nevertheless there is a difference between PVC and PU ... the
later one has much low dielectric constant which lead to a lower group
delay of a signal (the speed difference between low and high frequencies).
Beside after the crossover within the box you'll see(hear?) much more
group delay and phase shift.
