New for 2023, the 15 Signature Horn Speaker takes performance to a new level

TSS speaker design

Music reproduction from our Horn speakers possess a bouncy lightness and intense emotionality that makes you lose all sense of time. Or as a guest in our listening room recently put it: "A planned half hour turned into a whole night of music fun! You completely forget about the technology and listen to nothing but music".

The horn unit

Our horn is a very special development to meet our requirements. During the design process we excluded various materials such as plastic or wood from the outset for reasons of sound, we were left with a precisely defined construction. The horn is made of a special aluminium alloy and is drawn and shaped by hand from a single piece. The material thickness is also precisely defined as the horn only rests against the enclosure at one point for resonance reasons.

The compression driver

As you can see from our speaker specifications, we use in our top model 15 Signature a very large compression drivers of 5.0 inch. The requirements for these drivers are particularly extremely high, as frequency response and resonance require special attention, which we master through a special vaporization of wafer-thin shellac. Using these unique, exceptional drivers results in a very special reproduction of the music.

The bass woofer

All our new low frequency woofers are produced and optimized specifically for our bass horn. Features include a pure paper cone from only 68 grams for our 15 inch woofer at our 15 Signature. Specially developed for our needs and equipped with the best Thiele small parameters. Our 15 Signature has 99db efficiency, dual damping control, 4-inch inside/outside copper voice coil, super strong magnet from 28.5 BL this is unique on the market. Our bass horn woofer are capable of being sensitive enough to reproduce any style of music, regardless of volume. Listening to music that sweeps you away and touches you emotionally while offering a live musical experience between your own four walls and makes you addicted for more.

The cabinet design

It has long been known that a horn provides the most efficient transfer of acoustic energy to the air. It is also known that a properly designed horn type loudspeaker exhibits lower distortion, greater linearity, and more natural sounding reproduction than other types of loudspeaker systems. Bass Horns are also able to reproduce the dynamics of any given program material with stunning realism and minimum effort. Our specially designed bass horn utilises 4 different types of wood and has the incredible ability to deliver the tiniest dynamic changes and transparency completely independent of music style and volume. This speaker is able to recreate the emotions which are usually only experienced during live music events.
