What sets C1 apart?
JL Audio designed the C1 Series C1-400x 4" speakers to be the very best they could be for the price. You'll find solid construction and finish, along with some eye-popping flair in its striking yellow mineral-filled polypropylene woofer. That woofer delivers impactful lows and is specially designed for a natural roll-off transition to the highs handled by the tweeter. And it's the aluminum edge-driven tweeter that gives the C1 Series its distinctive sound, setting it apart from other speakers at this price. You'll hear crisp detail in the high frequencies, incredible imaging, and minimal distortion no matter how you power them.
Why no grilles?
Most folks have no use for aftermarket grilles, opting to use their factory grilles for a streamlined look. With that in mind, JL Audio doesn't include grilles with the C1 Series, opting instead to incorporate those savings into building an all-round better speaker.
