The Studer A3 is a high precision active near field monitor. Applying Group delay com-
pensation and Negative output impedance to a near field speaker represents a true innovation
in design philosophy, which makes the A3 speaker an impressive performer in its class.
The high SPL that can be produced over the whole frequency spectrum alongside the impressive
frequency response is quite unique for a speaker of that size.
The Studer A Series speakers are also ideal for surround applications. The Group Delay Compen-
sation makes the Studer series of speakers ideal for Surround Sound. Mixing and matching of
speakers is possible while correct phase response is maintained.
For all applications the A3 introduces a new standard of precision and will certainly change
your perception of near field speaker performance.
Key Features:
lHigh Sound pressure Level over the whole
frequency spectrum.
lFlat frequency response.
lHigh accuracy impulse behaviour due to
Negative output impedance
lHighly precise Stereo Image as a result of
the Group delay compensation
lDesigned for horizontal and vertical use.
lPrepared for stand and ceiling mounting.
lProtection circuit for each of the drivers.
lSeparate amplifier stage for each driver
(bi-amplified).
lRubber mounted non resonant power am-
plifier.
