ADAM AUDIO AD-A77X Near/Midfield Monitor, 3 way w/2 x 7'' Woofer

UPC: 260113133156

Description

ADAM AUDIO A77X

The A77X is a horizontally designed monitor that combines all of the technical innovations in the AX-Series. Due to its powerful, compression-free sound reproduction and excellent radiation characteristics, it is suitable both for nearfield and midfield monitoring.

The special feature of the A77X is its 2 1⁄2-way system. Both 7” woofers start to work together at 38 Hz and at 400 Hz one woofer fades out and only the second woofer continues to operate in the midrange up to 3 kHz. This prevents interferences and possible phase cancellation in the critical midrange. Even though frequency transitions and potential distortions lie outside these areas, the human ear is particularly sensitive to midrange frequencies.

Especially noteworthy in the A77X is the extremely wide stereo foundation and brilliant stereo imaging. Treble and mids are reproduced with three-dimensional realism and the lows are, as expected from a double woofer design, massive without compromising on precision.


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

In-phase, simultaneous operation of the woofers below 400 Hz
  • Dry, unstrained reproduction of the low-range
  • Critical center area is played by a single driver without interference
Ultra-light but extremely dimensionally stable woofer material (Carbon/Rohacell/Glass fiber)

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

Unique, horizontal 2.5-way system with 2 x 7" woofers

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
  • Allows positioning close to walls
Highly efficient PWM amplifier for the woofer coupled with an A/ B amplifier for X-ART tweeter

Low-distortion amplification at both low and high volume levels

Linear frequency response of 38 Hz to 50 kHz

Unbiased reproduction in a very wide frequency band

Maximum Peak sound pressure per pair in 1 m ≥ 122 dB
