## Overview

The Focal Polyglass 100 CVX 4" Coaxial Speakers combine a robust 200W peak power output with a durable glass fiber filled ABS frame and an adjustable aluminum dome tweeter. Designed for car audio, home theaters, and musical instruments, these speakers deliver clear, natural sound through a built-in 12 dB/octave crossover and premium components, all in a compact, easy-to-install package.

## Description

The 100 CVX is a 4 inch coaxial speaker from the Polyglass line of Focal speakers and features an innovative built-in 12db/octave audiophile crossover, which adds no mounting depth to the design. This crossover is constructed using polypropylene capacitors and air core inductors for an extremely dynamic and neutral sound. The unique Polyglass cone is made from a layer of hollow glass micro-spheres over a cellulose pulp which greatly increases the rigidity of the cone without adding weight. It has an Aluminum inverted dome tweeter on a rotating swivel mount for easy adjustments and controlled directivity.

Review: Good stuff - Sound Quality These speakers surprised me with their clarity for the price point. The polyglass cone woofer delivers solid mid-range, and I really like how the aluminum dome tweeter is adjustable - you can actually tune the highs to your preference. The built-in crossover does a good job separating frequencies cleanly. Build and Design Really impressed with the construction here. The 20% glass-filled ABS basket feels sturdy, nothing cheap about it. The butyl rubber surround seems like it'll hold up well over time. I noticed the aluminum cover protecting the crossover components, which is a nice touch most budget speakers skip. Installation At only 2.32" mounting depth, these fit where my old speakers wouldn't. The 4-ohm impedance works great with most head units. Power handling is realistic at 50W RMS each - I'm running them at about 40W and they sound clean without strain. Performance Notes The polypropylene capacitor and air core inductor really show in the sound quality - more natural than typical budget speakers. The 1-inch voice coil with copper winding handles power well, though I wouldn't push them to the full 100W peak rating. Overall Thoughts Solid upgrade speakers that punch above their weight class. Good materials, thoughtful engineering, and they actually sound like the specs suggest they should.
Review: Three Stars - Too thick to fix into my car's dash.

### ⭐⭐⭐⭐ Best 4" speaker I have ever heard!
*by A***S on February 3, 2017*

Only 4 stars because they can't handle a lot of volume. I paired with some focals KR3 and they can't even remotely keep up. Kinda expected but still amazing sounding speakers for 4"
