The sceptre (or scepter)åÊis the age-old symbol of royal authority. PreSonus Sceptre CoActual studio monitors do indeed provide sound quality and control worthy of the highest levels of aristocracy‰ÛÓbut they‰Ûªre priced for the bourgeois project-studio owner.

åÊ

The first time you hear Sceptre-series CoActual‰ã¢ 2-way studio monitors, you‰Ûªll discover fine nuances of your music that can‰Ûªt be reproduced by conventional designs. The Sceptre‰Ûªs panoramic soundstage, fine detail, and stunning dynamics will astonish you. This exceptional performance is the result of an advanced coaxial design that works integrally with a 32-bitåÊprocessor running Fulcrum Acoustic‰Ûªs TQ‰ã¢ Temporal Equalization Technology‰ã¢.

åÊ

PreSonus CoActual technology‰ÛÓthe core of every Sceptre-series studio monitor‰ÛÓis the combination of custom transducers in a state-of-the-art coaxial design with heavy-duty DSP running TQ algorithms.

åÊ

åÊ

The coaxial conundrum

Speaker designers have long been aware that coaxial designs offer the advantages of a single point source for a consistent acoustic center and a symmetrical dispersion pattern. But until now, designing coaxial systems without a variety of acoustic anomalies has been extremely expensive.

åÊ

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.

åÊ

However, Fulcrum Acoustic‰Ûªs amazing, cutting-edge technology has allowed us to overcome the usual design problems of coaxial systems while taking advantage of coaxial‰Ûªs unique properties. Thanks to custom transducers and TQ algorithms designed by Fulcrum‰Ûªs Dave Gunness, Sceptre CoActual monitors deliver clarity and coherence that has previously only been available in ultra-high-end systems.

åÊ

The royal Sceptre

The Sceptre series includes two models. TheSceptre S6åÊuses the same technology and design as the S8 but with a 6.5-inch low/mid-frequency driver. Both models have front-firing acoustic ports.

åÊ

The systems are biamplified: 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.

åÊ

All Sceptre-series monitors have a balanced XLR and å_-inch TRS line-level inputs with A-taper level control.

åÊ

To this package of custom transducers, powerful DSP running custom software, and first-rate power amplification, add a rich set of acoustic adjustments and full speaker protection, and you have a new,åÊaffordableåÊclose-field monitoring standard for project studios and commercial facilities.

åÊ

As you expect from PreSonus, Sceptre studio monitors use top-quality components and construction quality fit for royalty‰ÛÓand they look regal, too!

åÊ

Coaxial done right with TQ䋢

Each Sceptre monitor contains a DSP chip thatåÊenables the use of Fulcrum Acoustic‰Ûªs TQ algorithms. The processor is used to manage horn reflection, linear time and amplitude anomalies correction, performance contouring, and dynamic and excursion limiting.

åÊ

The result is coaxial speakers that perform far better than all but the most expensive studio monitors.

åÊ

You wield the Sceptre

In addition to making possible the Sceptre‰Ûªs coaxial design, the monitor‰Ûªs onboard DSP provides user-adjustable contour features for optimizing the monitors for your mixing space. This enables full integration into any studio environment.

åÊ

A four-position Acoustic Space switch controls a second-order shelving filter centered at 100 Hz, with four attenuation settings (no attenuation, -1.5 dB, -3 dB, and -6 dB) so that you can account for the boundary bass boost that occurs when the monitor is placed near a wall or corner. If you don‰Ûªt want to roll off those lows, set it to 0 dB.
