Sceptre™ S8: Accuracy and detail that will astonish you.
Hearing in three dimensions.
The lifelike, three-dimensional soundstage of Sceptre S8 studio monitors has garnered praise from some of the most critical engineers in the audio industry. Their unique design delivers pure and honest sound reproduction that brings to light subtle nuances in recordings that cannot be heard in other monitors. The result is panoramic imaging, finely detailed transient response, and stunning dynamics is nothing short of astonishing.
The CoActual™ difference.
The single point source provided by coaxial designs offers unique advantages, thanks to their consistent acoustic center and symmetrical dispersion pattern. The proprietary CoActual™ design in the Sceptre S8 relies on custom coaxial drivers and advanced onboard DSP to create a seamless crossover transition and an even frequency response. The net result is exceptional 3D imaging and a natural listening experience that reveals the subtlest details.
The PreSonus CoActual speaker begins with a well designed, horn-loaded, coaxial driver. With the high-frequency driver placed in the middle of the low-frequency driver, the response is symmetric both horizontally and vertically. This greatly increases the sweet spot and increases clarity and imaging.
The biggest challenge of any coaxial design is overcoming the intermodulation distortion caused by component interference. The horn-loaded design in a CoActual speaker uses the horn to prevent the high-frequency driver from interfering with the low-frequency driver. While this design has numerous benefits, anomalies on the throat of the horn can reflect back onto the low-frequency driver. This slight delay can cause speaker using this design to have an uneven mid-range response.
PreSonus overcomes this issue by using a powerful onboard DSP running Fulcrum Acoustics’ Temporal Equalization algorithms. TQ™ relies on fully addressable, fairly large FIR filters. These filters provide detailed adjustments in both the time and frequency domains. By using these filters to delay the horn to the back plane of the low-frequency driver, PreSonus CoActual speakers are able to produce an incredibly even mid-range with an inaudible crossover transition, allowing the finest details of your mix to be heard.
With a conventional two-way design that places the high-frequency driver directly above the low-frequency driver, where you are listening is critical to how well you will hear the audio. By contrast, the Sceptre S8’s frequency response is symmetrical horizontally and vertically, thanks to its coaxial design. When coupled with Fulcrum Acoustics Temporal Equalization algorithms, the result is a crisper stereo image, greater soundstage depth, more separation between components in a complex mix, and a less fatiguing listening experience.
