HELIX PF K100.2

The entry into the HELIX sound world

Enter the HELIX sound world with our PURE F speaker series. The powerful F-Series gets the maximum power out of your amplifier thanks to its 3 Ohms technology. In combination with the exceptional sound performance with powerful bass, clear mids and detailed highs, an exciting sound experience is bound to occur.

Easiest integration at its best!

The best sound isn’t any good if the installation causes trouble.
The PURE F loudspeakers demonstrate with their well thought-out design in every detail, how it is done the right way. This starts with the low installation depth of the drivers, which consider the increasingly limited space in modern vehicles. In addition, the system offers an extensive range of installation accessories with innovative bayonet lock for the extremely compact tweeter, which allows any installation option you can imagine, up to simplifications in the wiring thanks to our "Flex-Crossover" design.

Maximum flexibility – the "Flex-Crossover”

The sophisticated, two-part and immensely space-saving "Flex-Crossover" maximizes installation flexibility, for example when the tweeter is positioned in the A-pillar and the woofer in the door. This offers decisive advantages, especially in space-critical installations. In addition, the tweeter crossover is equipped with a two-stage level adjustment, which allows adaptation to both personal listening taste and the installation situation.

Cool design – noble materials

The timeless and stylish design of the F loudspeaker series with the dynamic Space-Line styling of the woofer cone is by no means an end in itself, but rather the result of the use of high-quality materials. The carbon fibres embedded in the polypropylene cone of the woofer optimize the midrange reproduction, whereas the coated silk dome of the tweeter guarantees exceptionally airy highs.

Effective but may be uncomfortable
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I have eczema on my feet and use a prescription cream that I leave on overnight. I often have a problem sleeping in socks but the silicone feels cool on my feet. The only drawback I have is the opening of the socks feel very tight around my ankles making them uncomfortable on me. I wish the opening was a bit more flexible.

Burned my already sensitive feet, too big
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
Feels icky, and the heat gets trapped and literally felt like my feet were being burned by these. The bottoms of these feel prickly and they are way too big. You have to sit still and cannot walk in them.

Just as good as paraffin wax
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I might prefer these socks over paraffin wax. They are comfy and very moisturizing. I use these socks once a week to keep the heels and soles of my feet moisturized between pedicures. I rinse with warm, soapy water then hang to dry. They are hard to walk in, but there's a saying printed in the socks that's says something to the effect of "take a break, stay off your feet" lol I love that as a reminder to put my feet up and relax

Love these!
Color: Pink & Beige, Size: Small(fits up to size 7)
Love these! As I write this review, I’m sitting in my recliner with these on. I have had other silicone socks in the past and would like to share a few of the things that I have learned. These fit great! The others were 2-3 sizes too big because you could not order a size. I wear a size 7 women’s shoe. I got the smaller size. I walked around my apartment in my old ones and they got kinda yucky. Now, I sit in my recliner, put them on and chill for a few hours. I now take them off and put in a ziplock bag so they stay nice and clean (no cat hair!). I use them once a week usually on Saturday or Sunday as I’m a working girl. Also, I use Auqaphor before I put them on and put cotton socks on after I’m finished. Your feet will be SO soft. This is not a one and done…I do this every week especially during sandal season! I know this was lengthy and I hope you got some tips.
