Atohm Sirocco Speakers, New Models!

We’ve been selling the French built Atohm GT Series speakers for a few years. All of our customers are impressed by the beauty of the finish and the power of sound from relatively small cabinets with a 7 year warranty. To be clear, Atohm builds its own drivers and cabinets in house in France. They don’t buy drivers from a third party in Scandinavia or Indonesia and “assemble” speakers.

Atohm has updated its smaller and less expensive Sirocco Series models, which are commensurately impressive at about half the price of the GT Series. The new Siroccos are designated the 24 Series since they were completed in 2024. They’re available in luscious walnut, black, light oak and white.

The resolution and imaging of the new Siroccos is STUNNINGLY good. If you want definition that’s as good or better than panels, in a modestly sized speaker that’s easy to drive, please visit to hear the Siroccos. You’ll find, as we have, that you can find speakers that bash more than Atohms, but you can’t beat them for detail and spatiality.

In addition to great clarity, the new Siroccos are going to impress you with their large image

and ability to play twice as big as they look. Remember, nobody has a living room like you do in France. The Siroccos look small but you can drive them to muscular volume levels.

You are allowed to buy them just because you want GREAT resolution and imaging from modestly sized cabinets. You don’t have to hit em hard- but you can.

Thierry Comte, Atohm’s owner and chief designer, writes the most detailed white papers in our biz. Ya wanna go down the rabbit hole?

New Concave Tweeter

Dubbed the WSD20, the new Siroccos employ this cutting edge driver. It uses a concave design with .75” Silk Dome drive element. The concave wave guide is made of machined, die cast aluminum (not plastic or MDF like the other guys) to assure its precise contour and uniformity with the C150 mid/bass driver. There are several other things to make this tweeter special. It has a machined aluminum phase bullet equalizer. It uses a double neodymium ring magnet system for optimal control. It has a rear dissipation chamber within the die-cast aluminum structure. The manufacturing precision of WSD20 is of very tight tolerance. No sample will vary from the reference standard by more than a quarter of a dB. That’s twice as tight a tolerance window as the best of the rest. The benefit to you- is spot on imaging. It’s fabulous!

New Mid/Bass Drivers

Dubbed the C150, the new Siroccos employ this high performance, cast mid-bass 6” driver. It features an NBR rubber surround with low diffraction surrounding technology. The cone material itself is a unique paper composite with proprietary treatment on the front and rear (different treatment on rear!) surfaces to attain the precise stiffness Thierry wants. This design has a very linear excursion which means they can use a less complex crossover network.

Cabinet Technology

Take a look at the meticulous internal damping composition of these bass-reflex enclosures. Thierry takes great pride in tuning/voicing all Atohm speakers.

Crossovers

Sirocco crossovers use soft slope 6dB per octave structures, complemented by impedance compensation circuits to allow virtually any amplifier to run the speakers. Thierry uses top quality parts such as air core inductors, MPT (Polypropylene) caps and low resistance laminated steel inductors. Internal wiring is multi-strand OFC cable.

Tweeter Tuning Control

The Siroccos have a 3 position tweeter level switch. We all have different electronics, rooms and TASTES. Thierry lets you make the decision as to what high frequency balance you’ll prefer.
