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.

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

Nice in a seal box

This isn't really your typical subwoofer. The sound out of my sealed BBox is clean and deep, the Focal hits hard. Powered by one channel of my Rockford 500 watt 2-channel amp. What I was looking for in my setup was clean sound, I purchased focal all around my car, sound dampened with Second Skin Audio, and added some clean tight bass. The bass hits deep, it will rattle your hair, but its far more tailored to rock, and punchy music. Deep long bass such as Trap, Dubstep, Rap really don't line up well with this subwoofer's strengths -- but that might also be my sealed box.

Doing a side by side on my roommates 2 Rockford 10" subs in a ported box, the Focal out preforms in every category. So I don't have a lot of complaints.

I might add a second.

Pros: Deep Clean Punchy - Great on bass drums

Cons: Not LOUD - but loud enough for adults

awesome 10"s !!

Best over all subwoofers I have purchased. Clean and natural sounding. Been a jl audio fan for last 15 years and now that I have focal. I will use nothing else.

Pros: Mirror magnet cover makes great visual in a custom enclosure. Very solid subwoofer. Protected tinsel leads. Solid spring loaded wire terminals. Great modest look to the face of the cone. Focal logo nicely centered on bottom of cone area.

Cons: Honestly can not find a con on this sub.

not very loud

I was disappointed in the overall output/performance of the sub. Sound quality is good, but not very loud. If you are looking for a sub that sounds good at moderate volume levels then this is a good sub.

Pros: great looking sub, good sound quality

Cons: unhappy with overall output/performance of subs. I exchanged these for 10w3v3 's and the difference in output is noticeably better with the JLs.

I have found my subwoofer!!

Crutchfield Customer Review (What's this?)

I installed a system about 4 years ago in my '05 GTO. I used the single din Alpine of the day. I first heard Focal speakers & I was floored. I used a 2 way 6.5" system up front & a set of their coaxes for rear fill. They are not cheap. I chose a JL 500/5 with a JL 10W3v. I was never happy with the sub, always tweaking the crossovers. The bass was weak and flabby, I was considering a 2nd one. Then my luck changed. The 10W3 fried! came apart at the seams. A clean signal & power, there's no excuse. I finally found Focal subs and ordered a 10" right up. The difference is night & day! It rattles my ribcage, I would need 3 of those JL's to get near the response & clarity on this Focal. It does a lot with less power so your amp works less. I will get another for my other car. Try one.

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 ]
