Studer A-5 Brochure
Studer A5
Active Main Monitor
The Studer A5 reproduces any style of sound with a previously unheard precision. This
precision is the result of considerable research in the field of “Group delay compensation” and
“Negative output impedance”. The innovative design of the A5 takes great care of these two
phenomenona, which make it a truly impressive performer.
The frequency response looks impressive but what really makes the difference is the SPL that
can be produced over the whole frequency range.
The Studer A Series speakers are also ideal for surround applications. “The Group Delay
Compensation“ 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 A5 introduces a new standard of precision and will certainly change
your perception of a main speaker performance.
