Product overview
Small, efficient and uncompromisingly stable – the M ONE X – 24V Edition is a highly compact monoblock for subwoofer applications. Designed from latest Class D technology this tiny amp can easily control speakers with 1 Ohm impedance. Its current capability makes the M ONE X – 24V Edition a perfect partner for 2 x 2 Ohms subwoofers, where both voice coils are connected in parallel. And for even more output power, two M ONE X – 24V Edition amplifiers can be combined to one single powerhouse – thanks to the TwinPower Link. In addition a comprehensive and stunningly practical feature set leaves nothing to be desired. Last but not least installation will be a no-brainer due to the minimal dimensions.
