The M 12 UNLIMITED and M 15 UNLIMITED subwoofers are designed for true SPL competitors.

The M 12 UNLIMITED and M 15 UNLIMITED offer the ability to choose the moving assembly which is most appropriate for the overall system design and conditions, achieving maximum SPL in every competition.

The innovative RMA, Removable Moving Assembly, provides the ability to replace the entire mobile assembly in few seconds, without removing the speaker from its mounting position. For each configuration you can choose the mobile assembly which is most effective, differing in the number of spiders, cone material and voice coil impedance.

The SPL Monster subwoofers will undergo continued modifications and upgrades, thanks to our ongoing research and the feedback we welcome from the competition field!
