The MS-30 reference monitor  system  is the result

of comprehensive R&D  effort  to develop  a compact

reference standard system for audio production in the digital

age. The development effort utilized extensive subjective

listening evaluations  and  proprietary  objective  instrument

testing procedures. The results are flat response not  only  on

axis but over the entire listening area, wide dynamic range,

and unsurpassed low distortion (both harmonic and time

related transient types).

The significance of  true power  response  accuracy

and  dynamic accuracy in a reference audio monitor has

become increasingly important with modern strides for

improved audio quality in  transmission,  recording  and

production. The EAW MS-30 is the first compact  monitor

system to offer significant improvements  in these  two

critical areas in 20 years. Benefits from the use of  the MS-30

include quality assurance  of  frequency, independent stereo

imaging, transient distortion, harmonic distortion, and tonal

balance.

Construction

The Eastern Acoustic Works MS-30 is constructed with

painstaking attention to detail because reliability is so  critical

in demanding professional applications.  The  many  extra steps

that EAW takes in the design  and  construction of the MS-30

provide considerable improvement  in performance  and

consistency. To maintain  that level of performance in every

MS-30 each unit is hand assembled and tested by  dedicated

craftsmen for absolute consistency.

High Frequency Assembly

The MS-30  offers  fiat power response due to the

careful design of  the 26 mm  soft  dome's  crosssection

contouring. The  complex  driver  mounting assembly  and

baffle termination prevent  any reradiated high frequency

energy from  creating time related off  axis response

deviations. Excellent transient capabili

ties are provided by the 18,000  gauss-in-the-gap  ferrite

magnetic circuit. Magnetic  dampening fluid  serves as a heat

sink for improved  power  handling while also lowering

distortion by dampening  out  cavity  resonances.  Increased

thermal capability in addition to  uniformly smooth and well

dispersed response results in high frequencies  with

exceptional reliability and sonic quality.

Low Frequency Assembly

Our 210 mm  (8") bass driver utilizes technology

which is years ahead of our competition,  allowing for

unmatched response accuracy and inaudible  harmonic and

transient  overhang distortion. From the proprietary

poly-laminated 

cone to the patented dynamic dampening

voice coil this driver represents true "state of  the  art"

performance. Through the application of  this advanced

technology we can eliminate cone Bell-mode resonances  and

distortion typical of all other vented  systems  when level  is

increased. The latest developments in voice coil adhesives

and former construction permit high power handling for  long

term reliability. The 33 liter (1.2 ft2  )  box  is  optimally  vented

for maximally flat response, providing good driver control

and excellent power handling below 100 Hz.

Frequency Dividing Network

The crossover is the heart of any  monitor  system

and the MS-30 utilizes the most  complex  crossover  available

in any professional studio monitor. Design  objectives  were

to eliminate even the  slightest abnormalities in both  the axial

and power  response of the system. All design parameters

were mathematically calculated, and then continuously

adjusted during extensive listening and instrumentation testing.

The resulting network is based on  a third order filter that

achieves precise phase matching, system equalization and

minimum interaction. Engineering design using many  units

enabled allowances for  driver tolerances  resulting in

production control of a consistency greater
