Sonance Professional Series PS-C63RTLP In-Ceiling Low Profile Speaker

Introduction

The Sonance Professional Series offers a range of architectural audio loudspeakers designed for commercial environments, setting new benchmarks in sound quality and aesthetics. The series includes In-Ceiling, Pendant, and Surface Mount Speakers, all delivering unequalled fidelity, extremely low distortion, wide dispersion, and a smooth power response. A consistent voicing across the range ensures seamless sonic integration within any space.

The PS-C63RTLP In-Ceiling Speaker features a shallow 4.37" (111mm) construction, ideal for installations in restricted spaces like those beneath HVAC ducting. It boasts a one-piece bezel-less grille, magnetically secured for easy installation and a one-step painting process. An optional Square Grille Adapter is available to match the aesthetics of square downlights and HVAC grilles, maintaining continuous sight lines.

This speaker is equipped with a high-excursion 6.5" polypropylene woofer for effortless low bass extension, even at high volumes. A pivoting chambered 1" soft dome tweeter can be directed for accurate coverage, even when speaker positioning is compromised. The PS-C63RTLP has a sealed metal enclosure with back and side knock-outs, a removable Euroblock connector with loop-through, and a seismic attachment. It is certified for UL 1480 and UL 2043.

Performance Measurements

The document includes several performance measurement graphs:

• 1 Meter On Axis Frequency Response: Shows the speaker's frequency response at 1 meter on axis, indicating a relatively flat response across the audible spectrum with some variations at higher frequencies.
• Impedance vs Frequency: Displays the speaker's impedance curve, showing a nominal impedance of 8 ohms with a minimum of 6 ohms, and a peak around the crossover frequency.
• 1 Meter Horizontal Frequency Response: Illustrates the speaker's frequency response at 1 meter at various horizontal angles (0, 10, 20, 30, 40 degrees), demonstrating consistent off-axis performance.
• Beamwidth vs Frequency: Plots the beamwidth of the speaker in degrees against frequency, showing how the sound dispersion narrows at higher frequencies.
• Directivity Index vs Frequency: Presents the directivity index in dB against frequency, indicating how focused the sound is at different frequencies.
• Polar Plots (1/3 Octave): A series of polar plots showing the speaker's radiation pattern at different frequencies and angles, illustrating its dispersion characteristics.
