C1-Series 4-Inch 35-Watt Coaxial Speaker System.

C1 speakers deliver real substance and great audio performance in a format designed for easy fit behind factory grilles.

To facilitate fit, breakaway mounting tabs on the woofer frame allow the C1-400x to be installed in four-hole or two-hole mounting configurations.

C1 woofer drivers benefit from proprietary FEA modeling and JL Audio's expertise in low-frequency driver design. This knowledge is used to create speakers that can play loudly, while maintaining a smooth, dynamic, low distortion sound. At the core of the C1-400x is a proprietary, stamped, steel 4-inch (100 mm) frame and a DMA-optimized motor system. A mineral-filled, injection-molded polypropylene cone is suspended with a rubber surround on the front, and a carefully engineered spider at the top of the voice coil, to precisely control motion and prevent impact between the voice coil and the back plate. Tinsel leads are carefully routed and attached to the spider to prevent fatigue and buzzing. These are the same kinds of features and materials normally found on much more expensive loudspeakers.

Equipped with a true, edge-driven, aluminum dome tweeter, C1 speakers stand further apart from others in its category with superior high-frequency clarity and definition. The tweeter’s design has inherently excellent off-axis response and high-frequency extension. It also benefits from the damping of a silk surround suspension and Ferrofluid in the voice coil gap, along with the superior strength of a neodymium magnet circuit. A true, 2nd order high-pass filter is employed to further enhance smoothness and improve power handling.

When it comes to value, C1 is the real deal!

Sold as a pair. Grilles not available.

Works VERY well, NOT sticky, smells AMAZING!
Size: 16 Ounce (Pack of 1), Style: Cool Down Lotion
So... I had sunburn... very painful across my whole back, top of my forehead & the back of my arms. Stupid, I know... USE SUNBLOCK PEOPLE! However, if u don't because u want "a little color" and end up like me, then I highly recommend this after-sun product. It smells amazing and doesn't leave the sticky residue like green Aloe Vera. After rubbing it in, my hands feel super soft. It gives my skin the hydration it needs so I won't peel (and lose the tan I was desperate for). My personal hack... After the sensitivity of the burn calms, I like keeping a bottle in the fridge for that extra cooling sensation. I love this stuff! Sun Bum is a great product... u should definitely try the sunblock tho, it worked where I applied it! I didn't take a pic for obvious reasons, but when u rub it in, it will dry clear.

Works Exceptionally well without feeling like you just applied Super Glue to your Body.
Size: 8 Ounce (Pack of 1), Style: Cool Down Lotion
I would provide a picture of the bottle but TSA took mine. This is some of the best post sunburn lotion I have ever used. I just finished writing a review of a sunblock lotion that did a great job, what I did not mention was the only sunburn I got was on my lower back where I didn't apply that lotion. It was a pretty uncomfortable burn, especially when I tried to sleep in the forward berth of a sailboat, or when I tried to wear swimming trunks with an elastic type waist, thankfully I had a couple of sets of board shorts that alleviated that irritation. But back on point. What I like the most about this lotion is how it applies. Usually, in the past, I did not like using aloe lotions because I felt like it was like glue when it dried on my skin and I felt like it made my skin feel tight. This stuff applies extremely well and I'm not exaggerating one bit when I say the relief is IMMEDIATE. As soon as I applied it to my sunburn, I felt immediate relief! It also doesn't feel like you just spread a bunch of super glue on your burn when it dries. It absorbs into your skin, cools your "hot spot" and doesn't leave a residue to get onto your clothing, or onto the mattress in my berth on the sailboat. Win and win. I can't recommend this product enough. The only negative experience was when TSA snagged my bottle going through security in Miami because I forgot to put it in my checked bag. But that was just the good ol' TSA doing their job in the amazing way they always do. (sarcasm dripping sounds) It works so well that I bought a replacement. So I would recommend purchasing the 3 oz tube if you plan on traveling with it. This is an excellent product, I'm not sure how long it lasts, because I forgot my sunburn was nothing me, or it enabled me to fall back asleep after applying. It does have that coconutty smell, but it's not like I just spent 3 hours in a hot tub filled with coconut oil. Hmmm... Idea forming... Anyway, purchase with confidence, this Texan who got a sunburn on his lower back and treated it with Sun Bum approves this message.
