The THE15 PRO ACTIVE EXT ON WALL requires a high quality powerful 2ch DSP controlled amplifier.

The The15 PRO ACTIVE EXT On WALL is an extremely impressive and extraordinary performing musical speaker system, that leaves nothing to be desired.

This 15"point source axisymmetric speaker has been designed as screen speaker for large theaters as left, center and right speaker or can be used for very large theaters as a surround speaker.

Each channel of the THE15 PRO ACTIVE EXT is capable of incredible SPL levels, but also the more impressive dynamic contrasts from whispering dialogues to explosive effects. The volume ranges your home theatre speakers need to be able to handle without audible distortion is huge, especially if you look for a reference level director’s cut performance - this level difference from softest to loudest sounds is called ‘dynamic range’. The The15 PRO ACTIVE EXT reproduces every possible dynamic range with ease. Even the most complex film passages with extreme dynamic requirements are reproduced at the highest clarity and lowest distortion. Imagine a life-like drum solo rendered exactly to the point by hearing and feeling the tremendous dynamic leaps of a bass drum and snare, while at the same time the humming of the cymbals fading away airily into the dark silence of the room giving way to the tiniest fine details.

This very precision lets the listener immerse entirely into the direct and intense visual action. Whether film or music – this sonic experience is not distinguishable from reality anymore.

The expertly engineered treated titanium dome compression tweeter is centrically arranged in the back of the 15-inch mid-woofer unit, and both drivers are driven by a separate (not included) DSP-controlled two-channel amplifier. Their results merge perfectly and allow for a time and phase-coherent lifelike reproduction of all acoustic events with reference level in every seat. The brain can therefore relax and stop trying to process the timing and phase errors far too common in other speaker designs. Advanced audio-over-IP technology and a sophisticated system user interface to control every function provide an unprecedented level of control and flexibility to the calibrator.

Combined with our PRO and Infrasonic subwoofers you will experience unimaginable realism of sound paired with sheer limitless dynamics. The15 PRO ACTIVE EXT ON WALL – The realistic cinema experience
