In Pakistan, SKYRS is the exclusive technical partner and authorized supplier for the complete FB-10 Subwoofer range, providing specialized structural rigging, acoustic balancing, and lifecycle support.
Variant Matrix
The FB-10 platform is engineered in three specialized variants tailored to distinct power management networks and structural demands across Pakistan:

| Frequency Range (-10dB) | 45 Hz – 1,200 Hz | 50 Hz – 1,000 Hz | 48 Hz – 1,200 Hz |
| Continuous Pink Noise | 120 Watts | N/A (Transformer Dependent) | 100 Watts |
| Continuous Program Power | 360 Watts Peak Handling | 240 Watts Maximum Peak | 300 Watts Peak Handling |
| Nominal System Impedance | 8 Ohms Direct Load | 70V / 100V Shared Line | 8 Ohms Direct Load |
| Line Tap Selection | N/A | 60W, 30W, 15W, 7.5W | Fixed Low-Z Overload Link |
| Enclosure Composition | Premium Density MDF | Particle Array Polymer | UV-Stabilized Polypropylene |
| Net Hardware Weight | 11.5 kg | 14.0 kg | 12.2 kg |
Technical Specifications
Nominal Sensitivity: 91 dB SPL (measured at 1 Watt, 1 meter)
Internal Crossover Guidance: Bi-amp active routing recommended (external filter separation at 80 Hz to 120 Hz)
Connection Terminal Input: Dual parallel-wired 4-pole Speakon/Neutrik connectors along with secure screw terminal strips
Enclosure Finish: Scratch-resistant textured polyurethane paint (Standard/High-Z) or molded matte resin (WP)
Deployment and Installation
Structural safety assessment, low-frequency pressure mapping, and specialized mechanical rigging are executed exclusively by certified engineering crews from SKYRS within Pakistan.
Boundary Loading and Floor Placement
To maximize acoustic efficiency, the FB-10 should be positioned strategically relative to architectural boundaries. Ground loading adjacent to structural walls or floor corners provides up to 6 dB of free acoustic output gain through mutual coupling.
Rigging and Flying Constraints
When suspending the subwoofer overhead inside corporate auditoriums or houses of worship, installers must utilize the integrated M8 threaded fly points with certified, load-rated structural forged shoulder eyebolts. A maximum bolt thread engagement depth of 20 mm must be maintained to prevent internal structural fracturing.
System Configuration
Acoustic spectrum crossover mapping, phase alignment verification, and power limiter matching are managed through authorized procedures to preserve local replacement warranties.
Step 1: Transformer Tap Mapping or Low-Z Verification
On the FB-10 Distributed High-Z version, access the rear input interface panel and set the rotary tap switch to match the designated system power budget (e.g., selecting 30W or 60W over a 100V network trunk). Ensure the direct Low-Z variant is never linked onto constant-voltage lines to prevent immediate voice coil destruction.
Step 2: absolute Acoustic Phase Alignment
Connect high-purity, thick-gauge speaker cabling to the terminal blocks. Using a phase analyzer tool, check absolute acoustic polarity relative to the main full-range satellite loudspeakers. Subwoofers out of phase with adjacent mid-high enclosures will create severe low-frequency phase cancellation zones, resulting in weak bass response.
Step 3: Central DSP Alignment and Limiter Settings
Program necessary parametric EQ balancing and processing protection blocks inside the central digital signal processor (DSP). Apply a strict high-pass filter cut (minimum 40 Hz, 24 dB/octave Linkwitz-Riley slope) to prevent sub-audible over-excursion, keeping the voice coil tracking safely within its magnetic gap during continuous high-output operation.
Service and Configuration Availability
The commercial distribution of all FB-10 Subwoofer variants, specialized rigging accessories, on-site environment spatial deployment, physical architectural installation, and final acoustic signal matrix tuning are available exclusively through SKYRS in Pakistan. Third-party structural additions, independent transducer modifications, or unverified transformer line loading will nullify the local five-year replacement warranty.
