About the JL Audio C1-650
Starter component speakers like no other
Starter component speakers like no other
After an extensive tour of JL Audio HQ, I got the opportunity to talk to their engineering and development team about the current JL Audio lineup and upcoming projects. Given all the work they're doing with premium car audio, I was surprised by how excited they were for customers to hear their workhorse C1 Series — speakers designed for drivers simply looking for a sensible factory speaker replacement, not necessarily an audiophile-grade solution. The reason for that excitement, once I heard it, made perfect sense — every JL Audio speaker must uphold the quality and sound associated with the name. You may be looking for something that's just listenable, but what you'll get with the C1 Series is an audio experience that puts it at the top of its class. And then, just maybe, you'll end up being a JL Audio fan for life.
What sets C1 apart?
JL Audio designed this C1 Series C1-650 6-1/2" component speaker system to be the very best it 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 separate aluminum edge-driven tweeter that gives the C1 Series its distinctive sound, setting it apart from other speakers in its class. 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.

Features
Woofers: Each JL Audio C1 woofer features a mineral-filled, injection-molded polypropylene cone with a rubber surround.
Size Classification Note: These speakers are marketed as 6½"; the woofers will fit in standard 6½" speaker openings, but do not use the standard 6½" speaker bolt pattern. In order to install them in standard 6½" speaker openings you must drill new screw holes. If new holes are drilled in the mounting surface of the car, no bracket is needed. If drilling in the car is not an option, the included brackets can be used, which have standard 6½" mounting holes, the Ford non-symmetric four hole pattern, and non-standard 6¾" three and four hole patterns. Please enter your vehicle information to confirm fit.
Power Handling: JL Audio publishes several power specifications for this speaker system, 50 watts continuous power handling (RMS), 225 watts peak music power, and 10-75 watts recommended amplifier power (RMS). We've listed the conservative combination of 10-50 watts RMS in the specs table.
Tweeters: The ¾" edge-driven, aluminum dome tweeters are damped by a silk surround suspension. Flush and surface tweeter mounting brackets are included.
Tweeter Dimensions:
| Frame Diameter | Cutout Diameter | Mounting Height | Mounting Depth | |
|---|---|---|---|---|
| Flush Mount | 1.675" | 1.448" | 0.248" | 0.863" |
| Surface Mount | 1.712" | Screw Holes Only | 0.748" | 0.508" (Screw Depth) |
Tweeter Crossovers: The in-line tweeter crossovers are 2nd order (12 dB/octave slope) and the 31" input and 14" output wires are attached. The input wires are terminated with female quick slides that plug into terminals on the woofers and the output wires are terminated with male quick slides that plug into the terminals on the wires attached to the tweeters. The woofer is unfiltered, using its engineered roll-off characteristics to blend with the tweeter. The electronic tweeter protection circuit is designed to minimize the possibility of tweeter failure. It monitors current going to the tweeter and will disconnect the tweeter from the signal when it senses overload. Once the volume has been reduced, the protection circuit will reset itself automatically.

These are good, the bass is good too. If you have a Honda civic it's best to turn your EQ off to get the most of out these as well. The tweeters are a bit loud, I had to lower the treble since my ears hurt after a while. Over all I love these.
