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.

Nice bar cart, Inaccurate shelf heights
Style: 3 Tier Cart, Style: 3 Tier Cart
Bar cart is nice, quite easy to put together. One of the most upsetting things is that the advertised/pictured 2nd shelf height is very wrong. It’s quoted at 18.1” tall but in reality it’s only 12.5”, the same as the bottom shelf - as confirmed in other reviewers photos. So half of my bottles have to go on the very top shelf. I reached out to the manufacturer about max shelf weight but they refused to give me an answer. I have about 30lbs+ on each shelf with the slightest bow in the center as there is only shelf support on the very ends.
