extended frequency response, excellent surge capacity and
very long life.
The inductors are air-core type, hand wound in
house, of unusually heavy wire for minimal loss and
exceptionally high power handling.
Each component in the crossover is matched to
within 3% of the original design values.
This crossover, the heart of the MS-50, is
unexcelled in quality and craftsmanship: Indicative of the
attention to detail during the design and manufacturing of this
system. We've also designed an acoustic contour control, in
the mid-range, and a high frequency level control which allow
for maximum flexibility in adjustment of the monitor for any
of the possible acoustic environments in which it might be
used.
Cabinet and Grille
The cabinet which houses the MS-50 is constructed
of a special high-density material, with walnut veneers on both
sides to prevent warpage and to reduce resonances. This
material, combined with a network of internal bracing and
acoustic damping materials, results in a virtually resonance
free enclosure. The front baffle is -routed out to allow the
drivers to sit flush. Then, a specially developed foam is placed
on the baffle to eliminate re-radiated high frequency energy.
The resultmuch smoother response than otherwise attainable.
The grille frame is made of rounded pieces which prevent
reflections back onto the baffle. As a finishing touch, the
acoustically transparent, black grille complements the hand
rubbed, oiled walnut finish.
Our Philosophy
At Eastern Acoustic Works, we're proud of the
state of the art products which we've designed and
manufactured. Our attention to detail, combined with the
very best technical skills available, allow us to manufacture
products which set new industry standards, are reasonable in
price, and which will last for a long time, even under the most
demanding conditions. Innovations which are useful and
practical have led to the development of the MS-50; the best
compact reference monitor available anywhere.
