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.

For the comfortable installation of maximum bass upgrades in BMW & MINI models

The CFMK200 BMW.1S adaptor has been specially developed for the installation of the Ci5 S200FM hybrid subwoofer, and thus for maximum bass upgrades in the factory mounting locations of all BMW & MINI model series with under-seat subwoofers. This adaptor ring is ideally adapted to the BMW- & MINI-specific shape, ensuring effortless installation and optimum sound quality. The pre-applied seals and the moulded-in connection terminal enable a professional as well as convenient installation. A connector housing for universal connection is also included.

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 Sound Sensation for sophisticated music lovers 

The HELIX COMPOSE i5 series is the link between i7 and i3, created for sophisticated music lovers with a sparked ambition for a true hi-fi experience. A lovechild of phenomenal sound and unmatched practicality: Developed with the vision of unique speaker highlights that are also true problem solvers. All speaker impedances are perfectly matched for the combination with our HELIX and MATCH amplifiers, guaranteeing maximum performance at any time. In addition, we implemented our COMPOSE-exclusive mechanical technologies that offer unbeatable practical benefits. 

Mid-woofer driver and subwoofer in one – the best of both worlds 

The Ci5 S200FM, as a 200 mm hybrid speaker, strikes the perfect balance between a mid-woofer driver and a subwoofer, impressing with its exceptionally high excursion, power handling and output volume. With its linear excursion of +/- 7.8 mm (D2: +/- 7.5 mm), it consistently delivers controlled and clear low-frequency reproduction, even at high sound pressure levels and low frequencies. The aim was to develop a speaker that works perfectly in BMW under-seat and Mercedes bulkhead applications without any compromises despite the extremely low installation depth of 47 mm. Thanks to the FlexMount200 technology, the Ci5 S200FM can be integrated comfortably and its design opens up completely new integration possibilities.

High-tech polymer basket

All HELIX COMPOSE i7, i5 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.

Flexible connection – 2 x 2 or 1 x 2 Ohms

The chassis are available as 1 x 2 Ohms (S2) or 2 x 2 Ohms (D2) version. Thus, these woofers always offers the right solution for every amplifier configuration to get the maximum performance out of it – whether mono, 2-channel or even multi-channel amplifier. 

FlexMount 200 – 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.

Good buy
Color: Blue-Green-Orange
Babies didn't use them. Too tough for their mouths. They are to small. Good for a bigger puppy.

Mastiff mix puppy loves them
Color: Blue-Green-Orange
I have experience with large working dog breeds, and I've got a mastiff lab mix puppy, who at 5 months weighs 50 pounds and is teething hard, and chews on everything. Most chew toys I've tried broke within a few minutes, but these have held up. I like that the ones I received are hollow, so I can put puppy kibbles inside them to keep the dog busy in her crate, and slow her eating so she doesn't scarf down her meals and get sick. The hole is small, but I feed small sized "taste of the Wild" brand kibbles, and they would pour out of Kong toys within seconds. I have recommended them to other puppy owners. My dog isn't an aggressive chewer, but for a teething puppy, these toys do seem to be ideal.

Nice material but do not recommended for aggressive chewers
Color: Blue-Green-Orange, Color: Blue-Green-Orange
Why did you pick this product vs others?: The material is nice and easy to wash but definitely do not recommend for large breeds/ aggressive chewers. My big pup ripped one up within seconds of getting it. The ball has lasted!
