PreSonus Sceptre S6 CoActual Active Studio Monitor

With a coaxial design that combines a 6.5" woofer and 1" tweeter in a common driver, the Sceptre S6 delivers a consistent center and symmetrical dispersion.

The first time you hear the PreSonus Sceptre S6 CoActual 2-way studio monitor, 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. This exceptional performance is the result of an advanced coaxial design that works integrally with a 32-bit processor running Fulcrum Acoustic's TQ Temporal Equalization Technology.

The Royal Sceptre

The sceptre is the age-old symbol of royal authority. The Sceptre S6 studio monitor provides sound quality and control worthy of the highest levels of aristocracy -- but they're priced for the bourgeois project-studio owner.

The system is 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. 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 an affordable close-field monitoring standard for project studios and commercial facilities.

Coaxial Done Right with TQ

Each Sceptre monitor contains a DSP chip that enables the use of Fulcrum Acoustic's TQ algorithms. The processor is used to manage horn reflection, linear time and amplitude anomalies correction, performance contouring, and dynamic and excursion limiting. The result is read more coaxial speakers that perform far better than all but the most expensive studio monitors.

No driver is perfect, nor can a driver be made perfect with hardware alone; there are always compromises in physical systems. To overcome these driver compromises, many speaker manufacturers apply DSP in the form of a combination of multiband EQs but the processing is more or less an afterthought -- it's not accounted for in the design of the transducer. This sorta works -- more or less. A few high-end loudspeaker companies have developed sophisticated solutions with active DSP that is co-designed with the speaker, but these are expensive solutions. So instead of taking the crude, old-skool approach, PreSonus partnered with Fulcrum Acoustic and licensed its high-end TQ Temporal Equalization, which, up until now, could only be found in very high-end speaker systems.

You Wield the Sceptre

In addition to making possible the Sceptre's coaxial design, the monitor's onboard DSP provides user-adjustable contour features for optimizing the monitors for your mixing space. This enables full integration into any studio environment. 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't want to roll off those lows, set it to 0 dB.

You also can adjust the Sceptre's overall sound and response using its performance controls. A sensitivity control that ranges from +4 dBu to -10 dBV helps you match the Sceptres to your mixer's outputs. The High-Frequency Driver Adjust switch adjusts the tweeter's overall level to linear (0 dB), +1 dB, -1.5 dB, or -4 dB. This lets you control the balance between the tweeter's output and that of the mid/low driver. The High Pass switch rolls off the low frequencies below the specified frequency (60, 80, or 100 Hz) at a slope of -24 dB/octave. This control is important if you are using a subwoofer in conjunction with the Sceptre S6 monitor; in that case, set it to the same frequency as the crossover to the subwoofer. If you're not using a subwoofer, you simply set the control to Flat.

These monitors are well matched, and the frequency response is nearly flat. The coaxial design is so well done, that you don't hear the speaker, just the music. Yes that sounds like a sales pitch, but it's true. They are some of the only monitors I've heard that reproduce the front edge of transients- They are so damn fast, and responsive that you will hear distortion in songs where you never knew they was any. The downside of all this speed, is that they don't carry a ton of heft. Bottom is clear, tight and accurate enough for all mixing tasks once you learn how they present bottom information. I added a sub eventually, but surprisingly the biggest benefit of that was being able to engage the low cut switch. Once everything under 100hz was cut these things turned into laser beams. No joke, the accuracy got even better and transient info even sharper;deeper. Awesome set for the price.
