Active 18" Bass-Reflex Subwoofer with 600 W/RMS Digital Amplifier!

The SUB618 is a bass-reflex subwoofer equipped with a 600W Class-D amplifier with SMPS power supply and an 18" high-performance speaker. Despite its compact enclosure, it delivers impressive sound pressure levels up to 133dB.

The SUB618 can be driven with either a mono or stereo feed, offers a phase inversion switch, and allows selection of the output mode (True Bypass or Xover).

For even more punch, the SUB618 features a boost switch that adjusts the frequency at the push of a button.

The unique audio performance enables the user to create a complete audio system with just one bass and two tops, without needing external electronics.

The compact enclosure of the SUB615 is made of high-quality multiplex and coated with scratch-resistant black protective paint. Using the M20 stand adapter, complete sound systems can be set up in no time.

Distance Rod

With the Pronomic distance rods, tops can be mounted directly on subwoofers – at the correct height. Almost all subwoofers already have a corresponding mount. The distance rods screw on with an M20 thread. A locking pin secured with a fixing screw prevents accidental slipping. The robust design guarantees long life even in the toughest stage environments.

I have now used the sub at 1/2 events and am convinced. Pushing quite well for a 12" sub, volume is definitely sufficient for smaller events.
