P 4

F l o o r-standing loudspeaker system

Product Summary

●

The P4 is the smallest speaker in the P Series, in order to achieve sufficient bass extension
the design engineers at B&W came up with a unique solution.

●

The key difference, which is not visible from the outside, is the internal cabinet construction.
A folded tapered duct has been used, which is selectively damped to give bass
reinforcement similar to a reflex enclosure, without the danger of pipe resonances that
would otherwise arise in the tall narrow enclosure.

Technical highlights

Kevlar®: B&W developed and patented the method of using Kevlar® for
loudspeaker cones to reduce unwanted standing waves. DuPont originally
created Kevlar® for use in bulletproof vests.
