About the Focal PSB200
From our tech experts at CEN
A Focal Polyglass 8 inch subwoofer, slim mount for vehicles where a conventional sub will not physically fit.
Who it suits
Drivers building a system where the bass has to keep pace with a capable front stage. Polyglass is a dependable mid-range option. Slim drivers open up door cards, under-seat spaces and shallow boots.
Our tech experts advise
A subwoofer is only as good as its enclosure and the amplifier behind it: volume and tuning decide what you hear. We build enclosures to suit both driver and vehicle at our Beeston workshop. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.

Frequently Asked Questions
Q: Do I need an amplifier for this subwoofer?
A: Yes, unless it is an active (powered) subwoofer with a built-in amplifier. Passive subwoofers need an external amplifier matched to the RMS power and impedance shown in the Specification tab.
Q: What does RMS power mean?
A: RMS is the continuous power a subwoofer can handle, and it is the number that matters when matching an amplifier. Peak or max figures describe short bursts only. Match your amplifier output to the RMS rating in the Specification tab.
Q: Can CEN build or supply an enclosure and fit everything?
A: Yes. CEN supplies enclosures and offers professional installation from our Nottingham premises, including amplifier wiring. Contact us to discuss your build.
Q: Is the PSB200 active or passive?
A: The PSB200 is a passive enclosure, so it needs an external amplifier rated around its 150W RMS, 4 ohm specification.
Q: How deep is the PSB200?
A: It is less than 5 1/8 inches (13cm) deep with the grille, so it fits easily in a car boot.
Q: What's in the box with the PSB200?
A: The loaded 8 inch sealed enclosure, four angle brackets, two 12 inch strips of carpet fastener, sixteen 1 inch screws and a user manual.
