Helix M ONE

Small, efficient and uncompromisingly stable – the M ONE 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 a perfect partner for 2 x 2 Ohms subwoofers, where both voice coils are connected in parallel.

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 its super-compact dimensions.
