HELIX CB C87.2-S3

HELIX COMPOSE. The perfect speaker for any composition. 

Born out of the increasingly demanding challenges of modern automobile technology and the HELIX-typical pursuit of intelligent solutions, we made the progressive redesign of proven universal speaker systems our mission. The result: our innovative HELIX COMPOSE platform that, according to the motto "developed inside the vehicle, for the vehicle", combines classic universal speakers with the advantages of vehicle-specific systems. Innovative materials and the latest technologies paired with smart, practical engineering – the best of both worlds in harmony: high efficiency, fantastic sound quality and enormous dynamics that fit in any vehicle. HELIX COMPOSE – universal speakers evolved.

The essentials for an exceptional sound experience 

You might have already guessed from the name: our BASIC component systems are the perfect introduction to the world of HELIX COMPOSE, providing all the essentials for an exceptional sound experience in your vehicle. All components harmonize perfectly and form an ideal team with our HELIX and MATCH amplifiers, guaranteeing maximum performance and power output at all times.

High efficiency 

HELIX COMPOSE equals smart engineering and accordingly implements highly efficient 3 Ohm technology, that perfectly harmonizes with all HELIX and MATCH amplifiers and at the same time allows a clearly perceptible plus in efficiency and maximum sound pressure. Certain models will also be available as an optional 2 Ohm variants, assuring the absolute maximum performance and power of the respective speaker in combination with the appropriate amplifier.

Powerful bass – always on point

In the BASIC series, our COMPOSE midbass driver combines high efficiency with excellent sound quality. The lightweight but stable polypropylene diaphragm provides exceptional sound performance while the sturdy basket is equipped with additional ventilation holes for optimized cooling. A powerful magnet system provides ideal impulse response and the soft polyurethane dustcap guarantees optimized frequency response in the upper midrange. Last but not least, the compact design is ideally suited for integrations in cramped spaces.

High frequency reproduction with unique dynamics

Of course, when entering the sound world of HELIX COMPOSE, precise highs are a must for an all-around exciting music experience. Accordingly, the tweeter uses a leightweight PEI dome as well as a highly efficient neodymium magnet – the result: unique dynamics in the high-frequency reproduction and crystal-clear sound.

Epilogues that left me wanting more
Format: Paperback
Book Review *minor spoilers* 3.5 stars I absolutely ADORE the Off Campus series by Elle Kennedy. Every book was fun, spicy, and dealt with real world problems, but with happy ever afters of course! I was SO excited to read The Legacy. An extended epilogue book dedicated to these characters?? Yes, absolutely love that idea. While it was very fun catching up with our favorite couples and seeing where they're at 2 years after their stories ended in their prospective books, I felt a little let down by most of them. I think my favorite epilogue story of the 4 couples was Grace and Logan. They kicked off the book with a bang. There was humor, emotions, spice, more humor. Plus the elopement!! I only wish we could have seen that part actually play out instead of a cliffhanger and then hearing about it through other characters later on. Dean and Allie. Gosh I loved this couple so much; their book (The Score), was my favorite of the original books. But Allie's character frustrated me so much when she didn’t want to accept Dean's proposal! Come ON girl!! Sabrina and Tucker. Their book was my least favorite of the original books, largely due to the plot focused around her pregnancy. Pregnancy tropes are just not my jam. And again, least favorite epilogue couple. Tucker opening two successful bars in Boston within 2 years - wildly unrealistic. Sabrina graduating Harvard Law while pregnant and raising her daughter; somewhat more realistic. Their story in the epilogue was entertaining, but it just didn’t do it for me. And Garrett and Hannah. My OG favorite couple. I loved their epilogue. I did not love that Hannah was so afraid to tell Garrett about her surprise pregnancy. But her reasoning was *somewhat* understandable. I will read anything I can get my hands on about this couple. But I just wanted MORE. More with the storyline about Garrett going public about his father's abuse. More about Hannah's career. More about G and H being parents - tell me about their kids! At least what are their names! Overall it was a fun way to wrap up the series. While I felt left wanting more, it's safe to say I probably wouldn’t ever be fully satisfied. Can Elle Kennedy please just write endless books about this characters? K, thanks bye!

hot hockey players in love ♥️
Format: Kindle
I have enjoyed this series so much 🥰Seeing all my favorite hockey players and their ladies get their HEA in these 4 novellas just made my heart all gooey 😍. I have truly learned to love these characters and the bromance of the hockey players, as well as the sisterhood of the WAGS. I all so glad Elle Kennedy wrote a continuing series 😘. Although my preference is sweet and clean reads, these spicy romances have captured my heart with their plot development and authentic characters. That being said this book, like the others in the series, have strong language and sexually explicit material. For mature audiences only. If you are ok with that, I highly recommend this series 😉

The Perfect Conclusion!
Format: Kindle
I was a little skeptical starting this one cause I’m not usually a novella person. BIG HOWEVER! This was definitely needed because I was already starting to miss the OG Briar kids! I’m not gonna go into too much detail since this is a spoiler free account, but I’ll just give you my thoughts on each novella: Logan and Grace: this one had me kicking my feet, giggling, and SQUEALING! It was so cute from start to finish and of course there was a little spiciness🤭 no complaints about this one! Dean and Allie: In the words of Jacob Black- “SHE’S NOT SURE WHAT SHE WANTS” and it irritated the hell out of me🙄 She was absolutely infuriating in this one and couldn’t wait for this part to be over🥲 Tucker and Sabrina: There’s started off a bit flat if I’m honest. I mean, they were just kind of. . .boring. Which is a shame cause they’re my favorites out of the whole series!😭 Graham and Hannah: Of course the OGs! Loved their portion of the book, until a certain part happened😐 I feel like Garrett didn’t handle it well, but he made up for it in the end. But this one was also so sweet because it showed how supportive they are to each other in their different careers. This book wasn’t overly spicy because it was more so about life after the college world experience, which is fine. There was still a fair amount of spice and I loved what I was given!😅 Last thing I’ll say about this book: I did not expect to laugh as hard as I did reading this! I mean I was legitimately CACKLING through this entire book!😂 Overall, I really enjoyed this one and loved seeing what our favorite characters were up to after graduation.

This product works.Worth the price!
Color: Mayday
My son had the worst sunburn I have ever seen. I looked for products and found this one. It said 3 times the relief. It is expensive it's around 50.00 dollars. I would have paid a hundred dollars to get my son some relief.If it would work. I should add that my son is grown.But his burn was so bad.He couldn't even take his shirt off without it hurting. I applied this product as said a p size shape.My son is a larger young man.He's almost six foot 220lbs.. I applied the product as said got him as comfortable as I could. And went on about my business. I checked back in and a couple of hours, and he said he felt some relief. I talked to him today and he goes mom. I feel a whole lot better. Unfortunately, he did blister, so he will have to go into the doctors. Just to be sure that blisters don't get infected. The relief he felt is worth the price.Anytime.. Just on a side note, I got natural witch, hazel and aloe vera.And when you mix the two together, it is a good compliment to this product to keep the skin moisturized as it's drying out. When I get the olive era product, I will write a review to see if it is good..
