SKY-8T-SUB: Frameless 8" 100V Line Ceiling Subwoofer

The SKY-8T-SUB is a professional-grade in-ceiling subwoofer designed to enhance the low-end performance of public address and background music systems. By extending the frequency response down to 50Hz, it provides a rich, full-bodied sound that transforms standard ceiling audio into a high-fidelity experience.

Seamless Integration & Minimalist Design

Just like the SKY satellite speakers, the SKY-8T-SUB features a frameless, low-profile aluminium grille. This oxidation-resistant grille is held securely by a twist-lock system and can be painted to match any ceiling finish. With the logo being completely removable, it ensures a discreet, integrated look that suits high-end retail, hospitality, and corporate environments.

Power & Flexibility

Equipped with an 8" polypropylene diaphragm and a high-quality 100V/70V line transformer, this subwoofer offers exceptional versatility for various installation scales. It features multiple power taps (60W, 40W, and 20W at 100V) and an integrated LC low-pass filter, ensuring it only reproduces the frequencies it was designed for—delivering tight, controlled bass without muddiness.

Installer-Focused Features

The SKY-8T-SUB is built to simplify the installation process. It includes highly conductive quick-connect terminals and a stable worm-screw mounting system. For added safety during installation, it features an anti-drop system and a dedicated safety cable hook, ensuring the unit remains secure in the ceiling at all times.

Key Features:

  • Rich Bass Reinforcement: 8" driver and 50Hz–200Hz response for deep, warm audio.

  • Frameless Aesthetic: Ultra-discreet low-profile grille with a paintable finish.

  • 100V/70V Versatility: High-power transformer with multiple taps up to 60W RMS.

  • Durable Construction: IP-44 rated, UV-resistant ABS, and oxidation-resistant aluminium.

  • Safe & Fast Install: Anti-drop system, safety hook, and quick-connect terminals.

  • Wide Dispersion: 170º coverage for even bass distribution across the room.

Ideal Applications:

  • Restaurants & Lounges: Adding warmth and depth to ambient background music.

  • High-End Retail: Creating a premium shopping atmosphere with full-range audio.
