The Paveosub-118sp is a lightweight heavy-vented bass reflex subwoofer for universal applications for mobile use and in fixed installations. This self-powered subwoofer is equip with a very strong 3-channel 4 kW power amplifier module and the DSP loudspeaker management system.

Equipped with a top-notch 18" neodymium chassis it produces a high and undistorted bass level from the most compact dimensions. The low moving mass, with a powerful driver (B/L factor of 28), for rapid and accurate signal reproduction with excellent attack and decay, is sonically superior to many other 18" speaker designs.

This universal, multiple use, high performance self-powered bass offers particularly excellent sound quality in a compact package. The 3-channel amplifier module makes the Paveosub-118sp ideal for building powerful satellite systems. The High Power Amplifier allows large dynamic reserves.

The Paveosub-118sp is a plug & play system. All the required settings for different configurations are stored as factory presets in the internal memory. For best performance and reliability, simply selecting the corresponding preset on the Display for use as either, a single bass in the stack with several basses, or as cardioide and end-fire bass arrays, or as a center of a Satellite system in conjunction with different tops.

The active electronics are convection cooled by a large heatsink and are maintenance free. No dust or moisture can be sucked or drawn in, making the Paveosub-118sp ideal for permanent installations. The robust cooling fins are amply rounded and have no sharp edges.

The control unit, DSP unit, signal connections and the Speakon OUT terminal are protected against moisture with a weather-proof, transparent cover. The cooling system is waterproof and the powerCON TRUE1 connectors are equipped with a rubber sealing cap.

The chassis has a large heavy duty 4" voice coil, a sophisticated ventilation system and a lower power compression than conventional bass drivers.

The power output is effectively used and the efficiency is maintained even under permanent full power use.

The substantial bass reflex ducts are located in four corners and the resulting chimney effect achieves good heat evaporation. The tunnel cross section equals to 500 cm², representing about 43% of the membrane surface, giving lower distortion and higher efficiency. Due to the large, open ports there is no air-flow noise. Any wobble effect is inhibited by the corner arrangement, as the air escapes from all sides creating a uniform back-pressure. The case walls are reinforced by this kind of tunnel setup again. Additional internal bracing provides stability and prevents unwanted resonances. Rubber feet and stacking cavities guarantee safe standing without slipping.

For cargo securing and lashing in stacks, two certified grommets are countersunk in to the side.

On top is an integrated M20 pole socket.


The woofer is in 8 Ω. The 18"chassis of the Paveosub-118sp is powered by one channel (1.580 W/8 Ω) of the internal power amplifier module. 2 x 800 W/4 Ω are available for satellite or monitors.

A Paveosub-118sp can power a second Paveosub-118 and power up to 4 additional speakers.
