Description
The Sirocco 2.24 is a hi-fi floorstanding speaker from the French brand Atohm, built according to a 2.5-way architecture with bass-reflex loading. It incorporates two C150 DCR08 bass-midrange woofers and a WSD20 DND04F tweeter, both developed in-house by the manufacturer.
The crossover is based on a first-order electrical slope with impedance compensation, a design that favours time coherence between the drivers. The frequency response extends from 40 Hz to 25 kHz, with a crossover frequency set at 3.5 kHz between the bass-midrange drivers and the tweeter. With a sensitivity of 89 dB/2.83V/1M and an impedance of 6 ohms, it accepts a rated power of 100 Weff (300 W peak). The cabinet is made of 18 mm thick MDF.
With its dimensions (990 x 216 x 256 mm) and sound footprint, this floorstanding speaker is aimed at enthusiasts wishing to equip small or medium-sized rooms without sacrificing bass depth or precision.

What to check before buying used
On this type of bass-reflex speaker with dual woofers, the condition of the diaphragms and the foam or rubber suspensions of both bass-midrange drivers should be checked, as these are prone to hardening or detachment over time. The tweeter deserves careful listening to detect any crackling or loss of definition in the treble. A visual check of the bass-reflex port and the MDF cabinet also helps identify any cracks or warping caused by transport or humidity.
