300-SD / 380-SD Speaker Datasheet
This datasheet outlines the technical specifications, product variants, and deployment frameworks for the 300-SD and 380-SD 3-Way Professional Speakers, distributed and installed exclusively by SKYRS Pakistan.
Product Overview
The 300-SD and 380-SD are high-performance, 3-way loudspeaker systems designed for clear, full-range audio reproduction in auditorium environments, commercial spaces, large houses of worship, and high-fidelity monitoring installations. Utilizing dedicated low, mid, and high-frequency drivers, these speakers provide exceptional vocal clarity and balanced acoustic dispersion over wide coverage areas.
Technical Specifications
Models: 300-SD (Compact High-Output) / 380-SD (Extended Low-Frequency)
Speaker Design: 3-Way True Acoustic Crossover Configuration
Driver Array:
High Frequency (HF): Precision titanium compression driver with constant-directivity horn
Mid Frequency (MF): High-efficiency horn-loaded mid-range transducer
Low Frequency (LF): 12-inch heavy-duty woofer (300-SD) / 15-inch extended-excursion woofer (380-SD)
Crossover Network: Passive internal 3-way Butterworth filter with built-in thermal driver protection
Enclosure Material: Multi-layered acoustic plywood with scratch-resistant textured coating
Input Connections: Dual Neutrik Speakon NL4 inputs wired in parallel for loop-through connectivity
Available Variants at SKYRS Pakistan
SKYRS builds and supplies three custom variations of both the 300-SD and 380-SD models to meet specific structural and environmental project demands in Pakistan:
Standard Performance Variant (300-SD-ST / 380-SD-ST) Equipped with rubber isolation feet, a standard pole-mount socket (35mm), and ergonomic recessed handles. Optimized for mobile corporate configurations, banquet halls, and semi-permanent setups.
Permanent Fly-Ready Variant (300-SD-FR / 380-SD-FR) Engineered explicitly for overhead suspension. Features twelve integrated M10 internal steel rigging points, a reinforced internal structural chassis, and a low-profile aesthetic.
Weather-Protected All-Weather Variant (300-SD-AW / 380-SD-AW) Upgraded for outdoor venues, public parks, or high-humidity environments. Features a hydrophobic grille cloth, silicone-sealed enclosure seams, a moisture-resistant treatment on the driver cones, and a gland-nut protected input terminal cover.
Deployment and Installation Services
Complete physical architecture setup, safe structural rigging, and audio line deployment are managed nationwide solely by certified SKYRS engineering teams.
Mounting Formats
Overhead Flying & Truss Rigging: Structural suspension utilizing rated steel drop cables, shackles, and fly bars secured to the building’s load-bearing infrastructure.
Wall Bracket Mounting: Installation onto structural columns or masonry walls via heavy-duty, adjustable tilt-and-swivel brackets.
Subwoofer Satellite Configuration: Pole-mount deployment using heavy-wall steel distance rods over matching low-frequency sub-bass enclosures.
Signal Routing Infrastructure
Low-Loss Power Delivery: Running high-gauge, multi-strand oxygen-free copper speaker cabling to maintain a high amplifier damping factor over long runs.
Patch Panel Integration: Termination through custom-engineered wall plates or central rack panels utilizing genuine lockable Speakon connectors.
Configuration and Availability
Advanced system calibration, multi-cabinet time alignment, and acoustic tuning services are available exclusively through SKYRS. No third-party adjustments are authorized or supported.
Calibration Parameters Handled by SKYRS:
DSP Optimization: Programming speaker processor endpoints (limiters, parametric EQs, and high-pass/low-pass filters) tailored to the specific power profile of the connected amplifiers.
Acoustic Time Alignment: Synchronizing the phase and time-delay between multiple 300-SD/380-SD fill speakers scattered across an architectural space to prevent acoustic cancellation.
Spatial Spectrum Flattening: Utilizing calibrated measurement microphones and real-time audio analyzers to map the venue’s acoustic response, adjusting equalizers to eliminate harsh reflections and optimize vocal intelligibility.
