We're one of those people who thinks carbon fiber can take an "ok" product into the realm of "showstopper". We also love the intrinsic properties of this man-made material which offers numerous advantages compared to plastic and metal; lightweight and strong, smooth, with a constant surface finish. Since all the layers are placed in a specific orientation, you don't have holes and gaps that are unavoidable when using natural materials like real wood either, making it a fantastic material for audio speakers...
Pagani Carbon Fiber Sound System.
Italian supercar makers Pagani, have released a stereo system which incorporates their technical knowledge, as well as their expertise in working with carbon fiber. The design of the Pagani stereo system is directly inspired by Pagani's Zonda line of cars, featuring similar controls and even the bass tubes, are designed to represent Pagani's signature exhaust. The stereo has two vinyl turntables, one for both 33 and 45 rpm discs as well as a CD player and the speakers are 350 watts. The Pagani stereo and speaker system is made entirely of carbon fiber and aluminum and is available by order only.
Magic Flute Speakers by SW Speakers
These are made of Carbon Composite, which doesn't have the weave pattern of the normal carbon fiber, but still has all the advantages of using full layered carbon. These speakers are acoustically optimized and are able to produce extremely accurate fluctuations in air pressure emanation from the cones. They are 5 feet tall with a total power of 300 watts. You can even tilt the tweeter cabinet for a somehow customized sound. It's a four way system with a large magnet sub woofer and a simple, yet effective crossover design for a smooth, roomy sound.
The Fat Lady by Morell HiFi
The use of the composite material, allows the Fat Lady to reproduce instruments with a timbre that is uncannily like the real thing with great balance and lack of sound coloration that puts it in the near perfect listening experience. We love the organic look and of course the sound quality coming from these units. We think carbon fiber will be taking over the manufacturing process of hi end luxury speakers.
You can always go the DIY route, like Ben Simpson from Australia. Pretty amazing results and not even mention about the low resonance levels he achieved and the improvement of the mid range sound quality.
