HELIX Ci3 W165FM-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.

Price-performance highlight

Our HELIX COMPOSE i3 series is an absolute price-performance highlight, providing a first-class sound experience thanks to high-quality components and smart engineering. As you already know from our i7 series, our new mechanical technologies with unbeatable practical benefits, are implemented here as well. All speaker impedances are perfectly matched for the combination with our HELIX and MATCH amplifiers, guaranteeing maximum performance at any time.

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. 

Cenosphere paper cone

With the innovative "Cenosphere" coating, hollow spheres are incorporated into a polyamide layer that is applied to the cone. This process increases the stiffness and also optimizes its internal damping. The result is an exceptionally stable yet lightweight cone that offers outstanding precision in sound reproduction.

High-tech polymer basket

All HELIX COMPOSE i7 and i3 speaker baskets are made of a high-tech polymer composite, which has been additionally reinforced with glass spheres. The result: maximum stability with minimal self-resonance, while also eliminating flux modulation of the magnetic system and maximum resistance to thermal influences. Last but not least, this allows for much more compact basket dimensions and thus simplified installations in cramped installation conditions.

FlexMount165 – Universal meets car-specific

FlexMount is a mounting system based on specially developed adaptor rings, allowing the installation of COMPOSE FlexMount speakers in an almost infinite number of vehicles. Thus, the universal loudspeaker effortlessly becomes a vehicle-specific loudspeaker, that can be easily installed in the original installation position of the vehicle in an acoustically optimized way with the matching FlexMount adaptor ring.

ProConnect – The new industry standard

Our innovative ProConnect terminal is the new industry standard: A professional, automotive connector, allowing the safe use of conventional speaker cables, while also being ideally designed for connection via flat plug with our WireKits, offering maximum flexibility in the design of the sound system upgrade. Furthermore, the connection is interlocked, offers reverse polarity protection and is electrically and mechanically highly stressable.

WireKits – Plug & Play at its best

Our WireKits realize the connection of HELIX COMPOSE components to the original wiring harness, or optionally to the crossover, in the most comfortable way. With manufacturing according to the high standards of the automotive industry, these arrestable adaptor cables meet all requirements for the harsh environmental conditions that installers are facing in vehicles every day.

Great book, so-so cover.
Format: Paperback
I must say, it is a top quality door-stop. My girlfriend gave me this book about six months before she left because she found it super informative, but I have to say that I knew how I would use it from the start. I mean, the weight of this thing could be easily understated by 0.2 to 0.3 lbs... The muted blue palette over the cover is an unobtrusive way to make sure the door stays open by just the right amount without it being too heavy or tough on hardwood floors (like a brick or a big rock). Why not five stars? The guy on the cover seems to creep out my cat. Maybe they should have put Mr. Bean or some other comically expressive figure on the cover rather than some random Thai guy...

Superb biography and history.
Format: Hardcover
I read this book prior to a tour of China a few months ago. I remember the old videos of China in the '60's and '70's showing the Chinese wearing Mao suits and riding bicycles. Now Beijing and Shanghai have freeways like L.A. filled with Audis, Buicks and other modern cars polluting the air. Much of the population dresses stylishly, particularly the young (many of them the "spoiled children" resulting from the one child law). They have a railroad that is an engineering marvel that goes to Lhasa, Tibet reaching an altitude of 16,000' on the way. Shanghai is the busiest port in the world and has spectacular skyscrapers. Do they have problems? Yes, huge ones including pollution of all sorts, lack of individual freedoms, a restless population among both the poor and well to do, rebellious minorities, and corruption throughout the ruling communist party. Still the changes in the last 30 years are astounding. No one man is responsible for all this but Deng must get the credit for leading the country to a more pragmatic economic path. No small task after the multiple debacles left behind by Mao and his ideological fantasies. It seems to be that the more ideological a political leader becomes the further he becomes separated from reality - whether the ideology is left or right. And if the ideological stance is extreme they soon begin killing people. Mao killed some by intent and millions by incompetent leadership and egotism. Deng and his supporters led hundreds of millions out of poverty. He was no angel and was part of a bad system throughout his long adult life. But his life is a great story and I would recommend this book strongly to anyone with an interest in modern China.

Format: Paperback
If you have to read only one book on China, pls pick up this one. Dr Vogel has done an amazing job writing about one of the greatest leaders in modern times. In order to understand the enormity of Deng's achievement, one needs to first appreciate the damage that Mao did to the country. Vogel gives a good background of that but quickly moves on to Deng. The approach described has value in achieving anything in life: Do more, talk less. Boldy try and if unsuccessful, adjust and try again. Choose good people, empower them and let them do their jobs. Respect the predecessors - watch his restraint at criticizing Mao - the man who made his life so miserable - 3 times! While his adoration of Deng is obvious, Vogel was also able to describe the human and less admirable side of Deng, most obviously, his handling of Tiananmen on June 4, 1989 and how he punished his protege (and one many regards as a just and capable patriot: Zhao Ziyang). China has gone through several leaders since Deng. But in spite of having all his history to learn from, none have come close, much less equalled the achievements of this great leader. Running a country is not easy. The larger it is, the more exponentially difficult. With more than a billion people, China is almost impossible to manage. Almost. Deng managed to and he did it extraordinarily well. This is his story. So well told that even Deng, would have approved. At $17, you really can't get a better bargain. I'm ordering a few more copies to give away to friends who really want to understand modern China.

Great book for recent China's reforms.
Format: Paperback
The author did a great job, really great job on this book. He has a deep understanding on China's rich history and how China gets where it is now. Mr. Deng is the right person for China, at the right (yet critical) moment. This book should be the "textbook" for any person who wants to know a little deeper about China. Deng's life represents the recent history of China. A poor student worked/studied in France in 1920s, being bullied and discriminated. A student in Soviet who saw the system may bring broken China back together. A high-ranking military commander who fought in battles to bring China to true independence in his 20s to 40s. A party leader turned exiler worked in a factory in his late 60s. A father who has to take care of a highly disabled adult son(was a bright student in a top university in China, and was threw out from a high floor window in Culture Revolution). A compromiser grabbed the absolute power in his 70s. A great reformer changed over 1.2 billion people's lives. A ruthless ruler doesn't allow his goal being sidetracked(1989 crackdown of street protesters). And finally, his goal, a stronger China, is here today. A great book.

Very thorough treatment
Format: Hardcover
This book provides a thorough treatment of the career of a man whose influence on China was arguably as great as anyone's in the 20th Century, Mao included. The picture that emerges is of a man who exercised good judgment, was a skillful politician, held certain core beliefs, but was pragmatic and capable of reversing course when necessary. I see parallels to FDR, in some respects. The author gives him credit for working masterfully within the Chinese Communist Party framework to achieve and exercise power, which required a certain amount of misdirection if not subterfuge, yet the prominent Americans who dealt with him all regarded him as being direct if not blunt to deal with. I am around 70% through the book and have branched off twice to read other books, which I almost never do. It occurs to me that this book is not a particularly easy read. In part this is due to the seemingly endless parade of characters whose identities can be difficult to keep straight. Part is due to the fact that Deng did not seem to leave behind much in the way of personal writings or interviews, so the book lacks a personal narrative feel. Also, a lot of Deng's accomplishments as a politician involved the indirect exercise of power, through others. Much of the book involves telling us not what Deng himself did in a given situation, but what Deng arranged to have acomplished, which doesn't involve the same urgency. There is very little revealed of his personal life. It is arranged topically within an overall chronology. It is very straight-forward, with basically no subjective content or even reflection. The book appears to have been exhaustively researched. It is well worth the effort, given the importance of the subject, which is, ultimately, China itself.
