This is a detailed description of a 400W, 2-way PA (Public Address) speaker system, which is designed for high-performance sound reproduction in various professional audio applications. Here’s a breakdown of the key features:
Key Features:
-
Power Rating:
- 400W RMS (Root Mean Square), providing continuous power handling.
- 800W Programme, referring to the peak power handling capability for short bursts.
-
Speaker Configuration:
- Two-Way System: Combines a low-frequency (LF) driver and a high-frequency (HF) driver for a broad frequency range.
-
Components:
- Low-Frequency (LF) Driver: A 15-inch (381mm) driver with a 3.0” (76.2mm) copper voice coil, delivering deep bass sounds.
- High-Frequency (HF) Driver: A dynamic horn with a 1.75” (44.45mm) voice coil, designed for clear high frequencies.
-
Frequency Response:
- 45Hz to 18,000Hz, covering the full range of human hearing for both speech and music applications.
-
Sound Pressure Level (SPL):
- 98dB SPL at 1W/1m, meaning the speaker outputs a sound level of 98 decibels when driven with 1 watt of power at a distance of 1 meter.
- 124dB Max SPL, the peak sound pressure level the speaker can handle without distortion.
-
Impedance:
- Nominal impedance of 8Ω, typical for most PA systems.
-
Crossover Network:
- Professional passive crossover that uses low-resistance inductors and high-quality metallized polyester capacitors, ensuring smooth transition between the LF and HF drivers.
-
Cabinet Design:
- Moulded Cabinet: Made from rugged polypropylene plastic, this cabinet is designed for durability and portability.
- Bass Reflex Port: Free-flow flared port enhances bass response.
-
Mounting Options:
- Equipped with a pole socket at the bottom for stand mounting.
- Flying Points: Three integrated M8 flying points (on the top and right side) for vertical or horizontal suspension.
Dimensions and Weight:
- Dimensions: 460mm (W) x 690mm (H) x 370mm (D).
- Weight: 22.10 kg.
