Gershman Acoustics Sonogram review
The Sonogram is a full range speaker designed and developed by E. Gershman
and the Gershman Acoustics team, using their experience, technology and
components, which were developed for the Gershman’s world-renowned
models such as the Black Swans, Gap 828 and Avant Garde to develop the
Sonogram. Even though the Sonogram is not the traditional Gershman’s
pyramid shape, Gershman Acoustics has developed a special technology to
eliminate standing waves inside the enclosure. This technology changes the
parameters of the inside shape of the enclosure. Therefore eliminating
standing waves resulting in exceptional sound clarity, neutrality and
imaging. An 8" Bass driver, developed by E. Gershman and custom made
for Gershman Acoustics, delivers very low bass, which is powerful, tight
and well extended to 28 Hz. The realisms and natural uncolored sound
conveyed by the Sonogram is rare to find regardless of price. internal
