Presonus Sceptre S8 - The first time you hear Sceptre-series CoActual™ 2-way studio
monitors, you’ll discover fine nuances of your music that can’t be
reproduced by conventional designs. The Sceptre’s panoramic soundstage,
fine detail, and stunning dynamics will astonish you.
Solving the problems involved in coaxial designs requires massive
amounts of DSP and subtle, sophisticated transducer design, which is why
such systems have, in the past, been limited to very high-end systems
with external processors.
However, Fulcrum Acoustic’s amazing, cutting-edge technology has allowed
us to overcome the usual design problems of coaxial systems while
taking advantage of coaxial’s unique properties. Thanks to custom
transducers and TQ algorithms designed by Fulcrum’s Dave Gunness,
Sceptre CoActual monitors deliver clarity and coherence that has
previously only been available in ultra-high-end systems.
Multi-way, non-coaxial speaker designs have long been the way to go in
speaker applications. But they suffer from the changing relationship
between the listener and the speaker elements: When you move around in
the coverage area, the sound is inconsistent. Even more troublesome, the
crossover point between the drivers can sometimes be audible.
Each Sceptre monitor contains a DSP chip that enables the use of
Fulcrum Acoustic’s TQ algorithms. The result is speakers that deliver
the full benefits of coaxial design. Sceptres provide extensive
user-adjustable contour features that let you optimize the monitors for
any mixing space.
The Sceptre S8 CoActual Studio Monitor combines an 8-inch
low/mid-frequency driver and a 1-inch (25 mm), horn-loaded,
high-frequency transducer into a single coaxial unit with aligned voice
coils. It has front-firing acoustic ports. The system is bi-amplified:
Each transducer is powered by a 90W RMS, Class D power amp with an
internal heat sink. Each Sceptre has its own internal power supply with
IEC connector and a power switch with on/off LED.
