Auditor Series by Focal

The 4” RCX-100 car coaxial speakers proudly carry on the audio legacy that Focal has proven time and time again. This speaker kit from the Focal’s Auditor series was built specifically with efficiency in mind. Focal wanted to offer a speaker upgrade for your vehicle that didn’t necessarily require you to add an amplifier to power them. The RCX-100s will run just fine off the factory-installed or aftermarket radio that you currently have in the dash.

Get Better Sound Than Stock

The factory-installed audio system in your vehicle is poor in design as well as quality. You can up the ante immediately by replacing the lackluster speakers with the Focal RCX-100 4” car speakers. Made up of a polypropylene woofer cone, Mylar inverted dome tweeter, rubber surround for the woofer, and more, the speaker is better-built and better-sounding. Perhaps best of all, the speakers are intended to run well off the existing audio system (radio or amplifier) so you don’t necessarily have to add much more than the speakers themselves.

Allow Us to Suggest…

If you already have an amplifier in the mix to power the speakers (or you don’t plan on incorporating one at this time), the next thing we would suggest is to use a Dynamat Xtreme door kit to provide sound insulation. In doing so, you’ll receive better mid-bass performance as well as help reduce incoming road noise through your vehicle’s thin metal doors so you can better hear your new speakers. There is enough Dynamat Xtreme material in this kit to provide sound insulation for a pair of doors.
