HELIX Ci3 W200FM-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.

FlexMount200 – 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.

Most comfortable office chair this fluffy guy has ever sat in.
Color: Black, Style: Classic
This chair is incredibly comfortable—easily the most comfortable one I’ve ever sat in. At around 300lbs, I’ve struggled to find a chair that’s both supportive and spacious. Most options feel tight, with the armrests pressing into my hips. Not this one. If anything, I feel small in it—there’s plenty of room on either side. It’s like going from a cramped budget airline seat to first class on a full-service carrier. The lumbar support is the best I’ve ever used. The materials are top-notch—everything from the base to the legs to the casters is metal (feels like steel). The casters themselves use what look like inline skate wheels and glide effortlessly across carpet—almost too well on hard surfaces, so you might want to consider a rug. Not a flaw, just something to keep in mind. I’ve paid twice as much for chairs that felt half as good, so in my opinion, this is an excellent value. The faux leather looks great and the stitching appears durable. While it may not last as long as real leather or high-quality fabric, it should hold up for a reasonable amount of time. Tilt functionality is basic—just two settings: upright or slightly reclined. Honestly, that’s all I need. If you’re looking for something to nap in, this might not be the chair for you. But for office work or gaming, it absolutely delivers all-day comfort. For reference, I’m 5'8", and the headrest aligns perfectly with the back of my head. If you're 6'5", it might end up being more of a neck rest. And I have to give a special shoutout to the included T-shaped hex wrench. It may sound silly, but this alone earns it a 5-star review from me. Every other chair I’ve bought includes those awful angled hex wrenches that make you slam your knuckles into the frame with every turn—often accompanied by some colorful language. Sure, I have my own tools, but finding where my wife hid them isn't always easy. A good-quality tool in the box? That’s thoughtful and appreciated.

Wide and comfortable office chair
Color: Black, Style: Classic, Color: Black, Style: Classic
It's made of very fine leather and in good quality. It has a pump to pump air to the back of the chair, so I can adjust the softness of the chair back. It's a very wide chair. Maybe the widest one I ever bought. I can only sit half of its space. It's very easy to install, the alignments are perfect. Its arm and height is adjustable. The wheels are advance ones which make it move through the floor smoothly. It looks an advance chair if you want an upgraded experience.

Comfortable Seating
Color: Black, Style: Classic
I honestly didn’t expect this chair to be this comfortable, but it has exceeded my expectations in every way. I sit at my desk for long hours every day, and the adjustable air-pump lumbar support has been a total game changer. I love that I can fine-tune the firmness depending on how my back feels that day. My lower back pain has noticeably improved since switching to this chair.The seat is wide, thick, and very supportive without feeling stiff, which makes long work sessions much more comfortable. The armrests are another big plus—they adjust in so many directions that I can always find the perfect position for typing, reading, or relaxing. The chair feels extremely sturdy and well built, and it gives me confidence knowing it supports higher weight without wobbling.Assembly was straightforward and took about 20 minutes. Overall, this chair feels premium, comfortable, and thoughtfully designed. I would absolutely recommend it to anyone looking for a reliable, all-day office chair.

Nice chair, w/ good cust support
Color: Black, Style: Classic
I apologize for length, but if I am doing a review for other people I assume you want to have as much info as possible to make a decision. I feel this chair is for tall/fat/both so will review it as such. At 6’4” @ 350lbs I fit into both, but reviewing based upon my body, yours is different so adjust according. TLDR – Would buy again, cavernous comfy chair with excellent customer support. Only personal dings against chair are the back could be taller, but added back due to support. Parts + Fit/Finish + Assembly: The parts have some heft and feel solid as expected for a chair designed for heavy people. Material and stitching look proper and I see no flaws. My box was beat to hell and ripped opened at one point. Packing material took the hit and did its job as the items were unaffected. The gas cylinder for the chair was missing and assume lost during shipping. (see customer service). Assembly was standard office chair fare with simple and clear instructions. Wheels / Height / Controls: I normally wouldn’t think of mentioning wheels, but it’s different than expected. They are good, maybe too good. A slight kick to push you back on wood floors sends you flying. The height adjustment for me is good/standard. At full height my feet are flat on the floor and where I would have the chair even if it went higher. My wife (5’6”) at that height is about 2.5 inches above the floor. Taller people than myself may wish for more height. Chair controls are standard fare and operate smoothly Seat: It’s large and with the arms is there is nothing even close to your hip/legs. I can put my fist on my hips and my arms barely touch the chair arms. This is why you are thinking of this chair, and for that you will not be disappointed. The seat is not pillow soft and IMHO a little firmer than I liked at first, but after a few days got broken in or I adjusted. I am a programmer + gamer so spend a lot of time in the chair for hours on end. Comfortable and no complaints at all. Seat depth for me is ~1” from my knee and good with roughly 20.5” usable butt/thigh length. That should be fine for big/tall but may be a bit much for big/short. Measure your current chair and decide from there. Back: The back lets the chair down a bit for me, the big/tall user, as the target seems to be big/short users. The back ends just below my shoulder-line. That obviously means no leaning my head back and the headrest is squarely on my shoulder blades. Not uncomfortable, but I’d prefer a taller back. For me personally I’d like it to be extended 4”, but that would likely be an issue for shorter users. I feel if the manufacturer increased the back by 2 inches it would be an ideal compromise for all users. The chair has an inflatable lumbar support, which I did not use as I personally find those uncomfortable. Also note the chair is designed for a more proper posture with a 90deg back and not a more relaxed 100-110deg. Neither pro/con as personal preference. Arms: The design of the arms being supported by rear only as mentioned earlier allow for an abundance of hip/thigh space. This is an excellent ergonomic design with a potential caveat. More stress will be placed upon the connection/joint. The joint for this chair is just shy of 4” so seems beefy but only time will tell if it holds up to the lateral force of leaning on it while reading. My chairs tend to last 5-7 years, due to the right arm feeling wobbly or the chair leaning to the right. The arm adjustments provide a nice front/back of ~3”, from touching chair back to 3” gap between chair/armrest. The height is similar and also moves the armrest forward about another 2”. At full forward/up the armrest are higher than I like so should easily accommodate taller users. Customer Service My chair was missing a part that I suspect was lost during shipping due to box condition. I contacted them Sun (7/20/2025 @ 1201). At 2228 that night I received a response that they acknowledged the issue and gave a tracking order for the missing part. The part arrived Mon 7/28 and gave a few days to test it out for review Fri (8/1). Obviously you don’t want an issue, but if an issue arises how a company handles it tells you a lot IMHO on how they feel about their product. I am very pleased with their handling of the matter.

Great Chair
Color: Black, Style: Classic
The durability, recline, noise, fit, and appearance, and stability of the chair were all fantastic. As someone of a shorter height, the backrest which is normally way to high or short for my head fits perfectly. The chair itself is easy to assemble and very comfortable to sit in for long hours. I tend do a lot of work at home and this chair feels very comfortable without feeling the need to get up. The chair looks great set up in my office and is honestly a great office chair. For moving around a room, the wheel guides across my carpet very smoothly with struggling unlike my previous chair which would need a heavy push. Not only that, the chair is noiseless which is a plus for people who get bothered by little sounds when moving around. The fit could honestly fit anyone of any size as the chair itself is quite wide and roomy for me. The seat is also made up of faux leather and feels well stitched and quite durable.
