The Subhorn-115sp is a self-powered hybrid bass horn complete with a top-notch 15" long stroke neodymium chassis, a 3-channel 4 kW power amplifier module and the DSP loudspeaker management system.

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 Subhorn-115sp ideal for building powerful satellite systems. The High Power Amplifier allows large dynamic reserves.

The Subhorn-115sp 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 Subhorn-115sp 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 extremely strong neodymium driver (B/L factor of 28) of the subwoofer reproduces low frequencies cleanly and accurately and at the same time produces a strong, punchy bass kick without being woolly. A clean attack and decay allows a high upper cut-off frequency and thus is useable with almost any top speakers.

The Subhorn-115sp is supplied in left and right versions. The basses are assembled with a large horn aperture providing optimal coupling of the sound field resulting in higher efficiency.

The hybrid construction of a single Subhorn produces ample bass. No stacking or doubling up of basses is necessary. (This is normally required with conventional horns in order to effectively provide low frequencies.) The stacking design of horns of the Subhorn-115sp with each additional bass has the advantage of enhancing the achievable lower cutoff frequency.

The stacking cavities and feet on the enclosure allow for horizontal and vertical stacking and ensure a safe arrangement without slipping. The bass can operate lying flat or standing upright. M20 pole mount sockets are installed on two sides of the housing.

There are 6 round handles affixed to the bass enabling handling by only one person. It is ideal for single or multiple usage. The Subhorn-115sp masters all sound reinforcement applications either for small events as a satellite system with spacer rod and top unit, or for an event of more than 10.000 people, in large stacks.

The removable front wheel board facilitates transport. The demountable boards are stackable.

The large 4" voice coil and elaborate ventilation openings in the magnet system make the chassis very strong, enable heat to be deposed and ensure low power compression. Unlike conventional bass horns, the 15" chassis in the Subhorn-115 is installed inverted for better heat eduction. The membrane cone operates in the sealed enclosure. The magnetic system is cooled by the air stream.


The woofer is in 8 Ω.

The 15"chassis of the Subhorn-115sp 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 Subhorn-115sp can power a second Subhorn-115 and power up to 4 additional speakers.
