Incredible Imaging

Sceptre™ S8: Accuracy and detail that will astonish you.


2-Way 8″ Coaxial Near Field Studio Monitor with DSP Processing and 180W Amplification

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 speaker designs offers unique advantages, thanks to their consistent acoustic center and symmetrical dispersion pattern. The proprietary CoActual design in the Sceptre S8 studio monitor 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.

Symmetric response.

With a conventional two-way studio monitor 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 studio monitor’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.

Accurate transient reproduction.

Consonant sounds in speech, percussion, attack and decay of musical instruments are all transient signals. Transients consist of complex combinations of many frequencies. The phase relationships of these individual harmonics are a critical part of the characteristic “sound” of an instrument or voice. When they are reproduced accurately, the result is sonic transparency, definition, and intelligibility. By maintaining the transient reproduction, even at high volumes, CoActual speakers minimize distortion and produce clean, clear, consistent audio at any SPL.

Monitors you can customize.

Sceptres-series studio monitors provide extensive user-adjustable contour features that let you optimize the monitors for your mixing space. This enables full integration into any studio environment. A four-position Acoustic Space switch helps to compensate for the boundary bass boost that occurs when the monitor is placed near a wall. A high-frequency driver level control helps to further mitigate room anomalies. An onboard highpass filter makes it easy to integrate a Temblor or other subwoofer into your monitor setup.

Accuracy defined.

The unique design of Sceptre S8 CoActual studio monitors delivers unmatched lifelike sonic reproduction and three-dimensional soundstage. Their ability to accurately reproduce transients and smooth frequency response will reveal subtle nuances that afford a truly honest listening experience.
