Rythmik F18 Subwoofer

Mass Where it Counts

Rather than standard 3/4" walls, our standard build for Rythmik F18 subwoofers features 1" thick walls and substantial bracing to further minimize cabinet resonance.

Finesse and Musicality

Non-resonant cabinet coupled with exclusive Rythmik Direct Servo technology insures that accuarate, impactful and genuinely musical bass. What more could you ask for?

Precise, Accurate and Musical Deep Bass

We have built many custom subwoofers over the years for all kinds of applications. But since Rythmik introduced their Direct Servo Technology, we've pretty much limited subwoofer production to Rythmik-based designs. They are simply too good.

It takes a lot of air movement to generate deep bass. And there is just as much energy coming off the rear of the subwoofer cone as there is initiated by the front of the cone. The result is a tremendous amount of energy being directed back into the subwoofer cabinet. This energy can easily create cabinet resonances and can cloud the clarity of the bass response.

We address cabinet resonance in two ways. First, with our Rythmik 15" builds, we use 1 1/2" walls rather than the standard 3/4" walls. This added mass lowers cabinet resonances to extremely low levels. We also add very substantial bracing to further reduce the chances of cabinet wall resonances. The result is extremely clean, precise and musical deep bass.

When set up properly, the sub should never call attention to itself. But your system will play significantly deeper than before and the sound will be very clean, accurate and musical...which is how it should be.

Enjoy...
