Features & Benefits

Product Feature
Benefit to the customer
X-ART tweeter, handmade in Berlin
  • Allows longer operation with fewer signs of fatigue
  • Their breakup is prevented by the folded diaphragms, distortions are effectively reduced to a minimum
  • Advanced dynamic range due to acoustically effective diaphragm surface that is 2.5 times bigger (compared to a classic tweeter according to the piston principle)
The air velocity ratio of 4:1 during the sound generation by folded X-ART membrane

Direct, fast response in the high-range even with complex transients

Ultra-light but extremely dimensionally stable woofer material

Excellent transient response even at high sound levels without breakup of the diaphragm

4-way system with 2 x 15" woofer and 2 x 9” midrange

Very high resolution of the stereo image and extremely wide stereo base

Spacious bass reflex ports on the front

Bass reproduction with very low compression

Highly efficient PWM amplifiers

Low-distortion amplification at both low and high volume levels

Linear frequency response of 20 Hz to 50 kHz

Unbiased reproduction in a wide frequency band

Maximum peak sound pressure per pair in 1 m ≥ 138 dB

Powerful, compression-free sound reproduction even at very high sound levels

Sophisticated room acoustic adjustments

Allows optimal adaptation to acoustically difficult listening environments or individual preferences

Analog XLR input

Optimized for balanced line signals

Directional sound radiation in vertical plane

Reduction of early reflections on the surfaces of, e.g. mixing consoles, desks, etc.

2 years warranty with optional extension to 3 years with the registration of the product

Full repair service if required for 5 years
