(2) Presonus Sceptre S6- 2-way 6.5" Coaxial Near Field Active Bi-Amped Studio Monitors With a 32-bit/96kHz Dual-Core DSP Processor 2-way 6.5" Coaxial Near Field Studio Monitor with a DSP Processor. CoActual technology combines DSP time-correction and point-source design for symmetrical soundstage and micro-definition imaging. Unique coaxial transducer integrates 6.5-inch midrange driver and 1-inch (25 mm), horn-loaded HF. transducer with Coaxial Speaker Coherence Alignment Powerful DSP provides critical Temporal Equalization with multiple FIR filters. Acoustic-tuning controls: HF Driver Adjust (0 dB, +1 dB, -1.5 dB, -4 dB), Acoustic Space settings (0 dB, . 1.5 dB, -3 dB, -6 dB), High-pass filter (Off, 60 Hz, 80 Hz, and 100 Hz, -24 dB/octave slope), Sensitivity (+4 dBu to -10 dBV). 180W RMS, Class D biamplification with internal heat sink. RF shielding, current-output limiting, and over-temperature protection. Balanced XLR and 1/4-inch TRS line-level inputs with A-taper level control. Amplifier 'soft start' feature eliminates popping on power-up. 102 dB maximum continuous SPL. Internal power supply with IEC connector. Power switch with on/off LED The Sceptre S6 uses the same technology and design as the S8 but with a 6.5-inch low/mid-frequency driver. The Sceptre S6 has front-firing acoustic ports. 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. All Sceptre-series monitors have a balanced XLR and -inch TRS line-level inputs with A-taper level control. 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, affordable close-field monitoring standard for project studios and commercial facilities.
