SONIC IMPROVEMENTS
Many of the sonic advances pioneered by the Savoy's sophisticated engineering was implemented into the Andra II including more accurate amplitude response, deeper bass, and higher efficiency. Above all, the overall transparency of the Andra was improved by utilizing the extremely high quality drivers in their optimum range instead of running them full range as in the previous design. This has allowed large increases in clarity due to optimized integration of the drivers. The target listening window has been opened up over a wide dispersion pattern, including vertically, in order to balance the rooms' reverberant response to the direct axial response. After an audition, we humbly believe you will agree that the sound of the Andra II is a world-class reference standard in timbre, image focus, impact and overall realism.

ENGINEERING IMPROVEMENTS
In order to raise the efficiency of the system and keep the overall impedance from dipping below 4 ohms, a new cabinet loading design and crossover were developed. The previous design used a ported pressure release system for both bass and midrange loading. However, this type of loading is inefficient and results in low impedances when used with normal crossover designs. The new MKII design utilizes a sealed system to improve the transient response, raise efficiency, and keep the impedance above 4 Ohms.

A new crossover was designed, using the driver reactances (impedance, inductance, capacitance of the raw speaker units), and the cabinet loading reactances as an integral part of the circuit in order to minimize the components needed and to keep the phase as consistent as possible. Flat amplitude response was the primary goal, as well as optimization of the transient response. The new circuit, although far more complex than the original circuit, is virtually transparent to the signal and allows the drive units to operate in their optimum range. The new circuit design enables a very large improvement in the system's clarity due to the elimination of "holes" in the amplitude response formerly caused by interdriver phase interference.

Naturally, the crossover circuitry utilizes the finest sound crossover parts available from companies of the highest regard in the industry.

DESIGN VERIFICATION
Sophisticated tests were performed at each engineering stage, including tests not performed by other manufacturers, such as internal air-flow tests using proprietary methods. Naturally, flat frequency response, wide bandwidth, low distortion, clean impulse and decay measurements were targeted and reached. However, measurements alone cannot predict "good sound", nor can they imply that the speakers will have an emotional impact of the listener.

In order to verify that the new engineering design was correct, "live music versus the speaker" - tests were conducted using our tube-driven AKG microphone. Live acoustic instruments were compared to the speaker's output, and voicing of the speaker was conducted over a period of several months in order to eliminate any coloration caused by the cabinet, drivers, and/or crossover.

The final result is an instrument crafted to play music like no other speaker on earth...ANDRA II.
