Hear the difference.
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.
The coaxial conundrum.
Coaxial designs offer the advantages of a single point source for a consistent acoustic center and a symmetrical dispersion pattern. But designing coaxial systems without acoustic anomalies has been extremely expensive—until now.
Meet Dave Gunness.
Here’s the speaker-design genius who solved the coaxial conundrum.
Dave Gunness is Fulcrum Acoustic’s Vice President of R&D, lead product designer, photographer, technical writer, and lead coffeemaker.
While at the University of Wisconsin, Gunness covered part of his expenses by singing and playing guitar over loudspeakers of his own construction.
Upon graduation, he made a living as a pro loudspeaker designer at Electro-Voice and later at Eastern Acoustic Works (EAW). Gunness holds five patents and writes technology white papers, many published by the Audio Engineering Society.
The KF900 large-scale sound-reinforcement system, the DSA digitally steered array, and a suite of innovative processing techniques marketed as “Gunness Focusing™” are all consequences of his career-long emphasis on improving loudspeaker performance with innovative software tools and DSP.
These days, he spends his time designing products and inventing new technology applications. Sometimes they let him out of his office to get a little sunlight and fresh water.
The Sceptre and our StudioLive™ AI PA loudspeakers utilize a lot of technology—acoustical know-how, DSP algorithms, user controls, and more—and were the result of collaboration between Dave Gunness and PreSonus’ engineering team. But the speaker magic is all Gunness. We speak his name with reverence at PreSonus!
The magic of TQ.
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.
Monitors you can customize.
Sceptres provide extensive user-adjustable contour features that let you optimize the monitors for any mixing space.
Big woof or huge woof.
The Sceptre series includes two models with the same high/mid coaxial section. The S6 delivers far better bass response than you’d expect for its size. The S8’s bass response is downright stunning.
