ROWEN Quad-Active technology
All the world is united on this point - active is better (than passive) but also elaborated! By the Active technology the sound quality can be significantly increased, as the dynamic disadvantages by passive crossovers do not apply, and the "pure" music reachs the different loudspeakers. The gain in intensity and the deep dimension picture gives the music a lot more expressiveness and concert-listening experiences.
With the ROWEN Quad-Active technology the sub-, low-, mid- and high-frequencies are threaded directly by separate amplifiers. The external Quad-Active crossover XO-Q delivers the correct frequency-spectrums to each amplifier.
The Quad-Active operation is possible with following loudspeakers:
ROWEN A12, L'Absolute 2, L'Absolute 1, L'Absolute
The ROWEN Quad-Active technology allows to bypass the passiv crossover in the loudspeaker and to drive the sub-, low-, mid- and high-frequencies directly by four seperate amplifiers. There's a Quad-Active crossover (XO-Q) and four amplifier-channels needed:
1×ROWEN PA4 4-channel amplifier
4×ROWEN MONO or ROWEN PA1 amplifiers
2×ROWEN ONE 2-channel amplifiers
