Focal Performance Sub P 25 DB
10" subwoofer with dual 4-ohm voice coils

Our take on the Focal Performance Sub P 25 DB by Crutchfield's Buck Pomerantz
Focal's Performance Series subwoofers deliver pure bass power so your music always hits strong and true. This Performance 10" sub features a light, tough poly cone and a self-regulating cooling system, so it'll perform reliably. A butyl rubber surround adds to the sub's strength, durability, and accuracy.
Performance and versatility
With heavy ferrite magnets and 4-layer voice coils, it's no surprise this sub handles plenty of power — up to 250 watts RMS. The good sensitivity rating means your amp won't have to work so hard to drive this sub, so you'll get maximum wallop per watt. The dual 4-ohm voice coils allow you to wire the sub for either 2-ohm or 8-ohm impedance, and you'll appreciate that versatility as your system grows and changes. You can install this sub in a sealed box for tight, punchy bass, or in a ported enclosure for a little more boom.
To drive this single subwoofer, we recommend a mono amplifier rated between 200 and 375 watts RMS at 2 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.
Great sub. No disappointment here

Spring-Posts: The P 25 DB uses spring-post speaker terminals for easy connection of single banana plugs or bare wire up to 10 gauge.
Rubber Gasket: The gasket/mounting-ring ensures better chassis damping and prevents air leakage. The rubber gasket is removable.

Ohms law. A single dual 4 ohm sub can only be wired to. 2 ohm. Or 8 ohm. You need a second sub to do a series parallel wire to get a 4 ohm load [ Randall Sep 20, 2015 ]
Yes [ Robert Turner Oct 24, 2016 ]
yes, you have to wire them in parallelled, not in series. overall resistance will drop to two ohms, just make sure you do not over power the speaker. 500 watts maximum at 2 ohms. [ LINDA Jan 09, 2014 ]
