T4 is the compact 2-way system with the highest level of performance, sound pressure levels, and audio quality. Its loading capacity down to the lowest frequencies and the FIR steering of the 2” driver is unmatched in the industry in regards to the lowest distortion and absolute phase linearity. With the 12”- long excursion woofer that can handle 700W and a 2” driver that can handle 140W, T4 gives you long term power with peaks of 2000W.

The sound dispersion in the mid / high horn is completely even across the audio spectrum and the HF wave front continues through the cut-off frequency as well as the crossover frequency, without any variance in the frequency response.


Both the 12”- long excursion woofer and the 2” compression driver have strong but light Neodymium-Magnets. The 4” diaphragm of the compression driver consists of a special material that has a clearly reduced distortion factor in comparison to a titanium membrane. With T4, KS AUDIO has responded to the demanding needs of the professional user with a modular 2-way sound system with the highest audio quality, yet in a compact size. There are many applications in which T4 can be used: Theatre, Live-stage Music, in large rooms or tents, as a delay system for long-throw, or as a compact top in combination with any KS AUDIO subwoofer, we recommend the T4 W sub.

The 12”- long excursion neodymium woofer with a 4 inch voice coil and the 2” neodymium driver with a 4” diaphragm will spoil you with it’s even and smooth dispersion characteristics.

The speaker cabinet construction is, like any KS AUDIO system, built from birch plywood with PU coating. All RAL colors available. 2 different horizontal dispersion patterns (60x40 or 90 x 40) are available. Another special feature is a pair of Aeroquip fittings on the speaker. Allowing the installation of different fly-ware and connectors, which are safely inter-locked. There is a pole mount in the bottom of the cabinet and a protective steel grill on the front, with or without acoustic foam, and handles on the top and sides are further features of this premium product.

Please note, all specifications are only achieved using KS AUDIO amplifiers and controllers.
