BLAM – French Style Aural Supremacy
Yes, the company is called BLAM. No, it's not satire that's been lost in translation. BLAM is acronymic for Bonneville Laboratory And More, named after its founder Guy Bonneville. Conceived in France during late 2013; BLAM is an audio brand built on expertise and passion. It’s a company created to give Bonneville and his engineering team the freedom to craft a distinctive sound known as The French Sound; a sound prized for its balance, smoothness and lifelike vocal reproduction. Rooted in France's long-standing aural traditions; BLAM stays true to a warm and natural sound signature, whilst continuing to innovate. Guided by its motto Driven By Passion; the company develops a wide range of high-quality audio products across different needs and budgets.

Indigenous Production
Based in Le Chambon-Feugerolles, BLAM operates with advanced research and development facilities and in-house production. This allows for close collaboration between design, testing and assembly; to ensure precision and quality is paramount throughout every design and manufacturing process.

Multix Barrel Series – Surpassing That Which Was Thought Unsurpassable
Although outdoing itself is a challenge growing more difficult by the day for acclaimed speaker designer BLAM, that doesn't mean this French electronic extraordinaire just gives up. BLAM's astute engineering team hold firmly to the belief that as materials and technologies evolve and improve, they can be incorporated into current and upcoming designs. Conducive to the endless enhancement of its already exemplary products.

This was recently the case with the flagship Multix range. Already recognised as some of the best car audio speakers on earth, BLAM engineers took these existing designs and affected various improvements across them, evolving them henceforth into the Multix Barrel range. Featuring everything from individual cones and domes right through to air motion transformers; the Multix Barrel components represent a range so superior that many competing speaker designers have simply thrown in the towel, begrudgingly accepting that BLAM is absolutely beyond reach insofar as true state of the art high-end drivers are concerned.

Design Ideologies
The Multix Barrel range from BLAM are engineered for those who demand nothing short of perfection from their sound system. Perfect clarity, perfect realism and perfect tonality. Designed squarely with audiophiles in mind, this stellar range of components features precision designed and manufactured hardware that delivers and powerful performance with longevity to match. The Multix Barrel range sets an impossibly high standard for realistic and absolute accuracy, with an entire stable of cutting-edge à la carte speakers and subwoofers. Thus allowing you to choose the size and type for your individual requirements and vehicle.

Technology Beyond Superb
BLAM’s superb AMT1 is a cutting-edge component designed to elevate the performance of any high-end audio system. Utilizing air motion transformer technology, the AMT1 features a pleated Kapton diaphragm. This excels in producing precise, crystal-clear treble with remarkable detail. This diaphragm structure also allows the unit to deliver high-frequency sounds with unmatched accuracy, extending well beyond 35000 Hz and ensuring every nuance of your music is captured in full brilliance.

The Powerful Motor Within
Powering this exceptional transformer is a powerful neodymium magnet, which guarantees low distortion and high efficiency. The combination of the advanced diaphragm and high-performance magnet enables the AMT1 to produce incredibly clear and dynamic highs, even at higher volume levels. With a maximum power rating of 100 Watts and a nominal power rating of 10 Watts, it’s well able to handle demanding audio signals while maintaining sound fidelity. The 6 Ohm impedance makes it compatible with a wide range of audio equipment, ensuring versatility in any system setup.

Function First
Designed with both form and function in mind, the AMT1 incorporates an aluminum front plate that provides enhanced rigidity and durability. This thoughtful design feature ensures easy installation while maintaining the unit’s structural integrity, even in challenging environments. The aluminum construction also helps with heat dissipation, allowing the driver to perform at its best, even during extended listening sessions.

Stylish Elegance
The sleek and modern appearance of the AMT1 is complemented by its transparent grille, which not only offers protection to the internal components but also contributes to its minimalist aesthetic. Whether you’re building a high-fidelity audio system or upgrading an existing one, BLAM’s stellar AMT1 is an excellent choice for achieving superior treble response and overall sonic clarity, all while adding a touch of elegance to your setup.

Coil-Less Concept
Air motion transformers represent a loudspeaker concept that does not require a classic voice coil. Using a thin Kapton foil measuring 12 µm – 25 µm in thickness, against a specially designed conductor track made of thin aluminum also only 12 µm – 25 µm thick); these ribbons move in a reciprocal motion to agitate air.

Wikipedia puts it like this: The diaphragm pushes back and forward from itself in a physical motion similar to that observed when an accordion is pushed in and pulled out to pump air through the reed chambers, albeit over an exceedingly smaller motion range. The result is a dipole driver with an extraordinarily rapid response rate, enabled by the extremely low mass of the polyethylene substrate and the far smaller distance it travels on each “swing” compared to a dynamic driver. In this technical respect, it shares characteristics with an electrostatic driver.

The discernible motion of each diaphragm flexure is very small, but because of the folded structure more air is moved than would be by a conventional cone or electrostatic driver of the same plotted surface area. As a matter of surface comparison, a standard 1″ / 25 mm AMT strip has a functional driver area comparable to an 8″ / 200 mm circular dynamic cone. The folded driver design, combined with the small motion range; means the AMT acts like a point source version of a larger driver, inherently resulting in lower sound reproduction distortion. The speed of the air as it leaves the diaphragm is approximately five times faster than the speed of the actual driver structure, hence the name Air Motion Transformer.

Can We Have That In Plain-Speak
If the above description is a little over the odds for your level of understand let’s break it down a little. Put succinctly; unlike conventional tweeter domes the folded AMT diaphragm in the loudspeaker does not make any movement from the front and to the rear to produce the tones. The movement takes place in the folds. This laterally, similar to a bellows. This causes the air in the convolutions to accelerate and exit the front. One advantage of this technology is that the diaphragm area is larger than the visible area and thus takes up less space. Coupled with the light weight of the diaphragm, this results in a detailed and dynamic reproduction.
