Our M3 Carbon 3.5″ loudspeaker is a no-compromise wideband solution for use in any high-end audio system. Smooth midrange fluidity, broad bandwidth, and low inductance are the key design elements on our M3 Carbon loudspeaker. Extensive Finite Element Modeling along with critical analysis data from Klippel USA was used to fine-tune the driver into what you see before you. The M3 Carbon has a Carbon Fiber cone and dust cap for lightweight moving mass to keep sensitivity as high as possible while providing exceptional cone stiffness. The Carbon Fiber cone is mated to a specific custom tooled synthetic copolymer surround which aids in smooth midrange and excellent durability. The dominant suspension damping force is provided by a Nonex spider between the spiral cut aluminum voice coil former and cast aluminum frame. Inside the motor cup lies a high-strength shielded N45 neodymium motor structure providing high motor force across a single gap motor structure. Inductance is kept low to increase the high-frequency extension up to 20,000 Hz which can negate the need for a tweeter when used on-axis.

While we call the M3 Carbon our midrange it is actually a wideband loudspeaker capable of playing from 125 Hz up to 20,000 Hz. We recommend a highpass crossover point equal to or greater than 300 Hz with a 24 dB/octave slope.

Perfect for sensitive skin
Style: SPF 50 Lotion, Size: 6 Ounce (Pack of 1)
I love this sunscreen. This was my first time buying after always using another company but recently my skin has started breaking out after using my old sunscreen. This sunscreen not only protects my skin but also does not give me a rash or irritate my skin.

This stuff WORKS.
Style: SPF 50 Lotion, Size: 6 Ounce (Pack of 1)
I am pale, I have rosacea, and I live in the south. That is a terrible combination. But this sunscreen has saved my butt (well, actually it’s saved my face). It doesn’t sting at, and when I accidentally got it into my mouth it didn’t leave a weird aftertaste (I smear it over my lips). This is my first mineral sunscreen, so I can only compare it to chemical sunscreens. But so far I think it lasts longer (and holds up to sweat better) than any other sunscreen I’ve used. It even survived a day at the water park with minimal reapplication. Now I will be honest, it leaves a white cast. But I don’t even bother trying to rub it all the way in. I just go out looking like Casper the Friendly Ghost. (Also it scored well on consumer reports, but the baby version scored even better, so I think I’ll try that next)

Works Great, soothing
Style: SPF 50 Lotion, Size: 6 Ounce (Pack of 1)
This is the best sunscreen I’ve used. I’m fair and after some chemical peels needed extra protection. This sunscreen is soothing and works perfectly. Blocked me from any sun damage and I live in a very sunny location by the ocean.

Zinc Oxide Sunscreen is the best choice!
Style: SPF 50 Lotion, Size: 6 Ounce (Pack of 1)
I’m happy I decided on Coppertone Pure & Simple Zinc Oxide Sunscreen. The 6 ounce bottle is well worth the price as a little goes a long way. I always give the bottle a good shake before applying it. This was the first year I sought out all zinc oxide sunscreens. I wanted to avoid the bad ingredients in regular sunscreens I’ve used in the past. This is free of octinoxate & oxybenzone which are the 2 main bad ingredients in most sunscreens. This pure & simple sunscreen is free of PABA (para-aminobenzoic acid) which is an ingredient you should avoid in the interest of protecting your overall well-being. It’s also parabens, dye & fragrance free. I like the 50 SPF. I did some research on what it’s a good SPF to look for. This is what I learned: “SPF50 will last 2 hours in the sun. It should protect you 50 times as long as your skin would be able to naturally protect itself. However, remember that the lower the SPF and longer the length of time since application, the less UVB rays will be filtered so a reapplication every two hours is highly recommended.” Another great feature this sunscreen has is the active ingredient of zinc oxide is at 24.08%. I didn’t know what that meant so again I researched it. This is what I learned: “It’s recommended looking for a sunscreen label for a zinc oxide concentration of 20-25% for best protection from UVA and UVB rays.” So thumbs up on everything this Coppertone Pure & Simple sunscreen offers. Be careful as it comes out a little watery quickly but it rubs nicely onto my skin & is absorbed immediately. There’s no residue or white cast look to it period. Yesterday I worked outside for 5 hours. I took a couple breaks & did reapply after 2 hours. I didn’t burn period. This sunscreen kept my skin safe. I also decided to apply it to my face because I had it handy with me outside & my face sunscreen was in the house. This was lightweight on my face & didn’t irritate my sensitive skin. I feel it could easily be used as a facial sunscreen. So many positives I’ve found with this sunscreen! I most definitely recommend it!
