Focal
designed the PS165V1 to be the most versatile speakers in their
Performance Expert lineup. Every aspect of this set is based on fitting
into your system easily. The shallow mounting depth of the midwoofers
and separate passive crossovers are designed to fit in tight spaces
where most can't. The extreme efficiency of the set also makes it so
versatile it can run on anything from a factory deck to a strong
aftermarket amp.
