JBL Control 419CS/T 8" Passive Ceiling-Mounted Subwoofer (Pair)

Product Overview

The JBL Control 419CS/T is an 8-inch passive ceiling-mounted subwoofer designed for commercial distributed audio systems that require extended low-frequency reinforcement in plenum-rated installations. Sold as a pair, the 419CS/T integrates directly with the JBL Control 400 Enhanced Coverage Series full-range ceiling speakers to deliver warm, natural bass in conference rooms, retail environments, hospitality spaces, and houses of worship. A built-in passive low-pass filter simplifies system integration, and the multitap 70V/100V transformer supports both distributed and direct 8-ohm configurations. IP33-rated for protection against dust and light moisture, the 419CS/T is built for long-term reliability across a wide range of commercial ceiling environments.

Product Description

The Control 419CS/T extends the low-frequency capability of any Control 400 series installation without requiring an external crossover. Its 8-inch woofer uses a 1.5-inch copper voice coil on a fiberglass former, delivering up to 640W peak power handling with low distortion and strong long-term reliability. Two large tapered ports produce smooth, controlled bass response that blends naturally with full-range ceiling speakers above it.

The integrated 60W subwoofer-band multitap transformer is engineered with low saturation characteristics, which keeps distortion minimal even at elevated drive levels on 70V or 100V distributed systems. For direct-drive applications, the transformer can be bypassed for 8-ohm operation. In 8-ohm mode, two 419CS/T units can be paralleled on a single 4-ohm-rated amplifier channel for additional output and bass extension.

Designed for both speed and safety, the dog-ear mounting system accommodates a wide range of ceiling thicknesses and provides top and side cable entry options through captive terminal covers that close without tools. The full-face magnetic grille attaches tool-free and includes a safety tether anchored directly to the baffle. Optional square and black accessory grilles are available to match architectural requirements. The 419CS/T ships with a white round grille, C-ring, and tile rails for standard plenum ceiling installation.

Key Features

• 8-inch woofer with dual tapered ports — delivers smooth, extended low-frequency response for commercial ceiling systems.
• 640W peak power handling — 1.5-inch copper voice coil on fiberglass former for high output with low distortion.
• Built-in passive low-pass filter — enables direct parallel integration with Control 400 full-range speakers, no external DSP required.
• 60W multitap subwoofer transformer — supports 70V and 100V distributed operation; bypasses to 8-ohm direct drive.
• 8-ohm parallel operation — two units can be paralleled on a 4-ohm amplifier channel for greater output.
• IP33 environmental rating — protected against dust ingress and light water spray for broad commercial deployment.
• Magnetic bezel-free grille with safety tether — tool-free removal, clean architectural look, baffle-mounted tether for code compliance.
• Top and side cable entry — captive hand-screw terminal covers accommodate varied rough-in conditions without additional hardware.
• Plenum-rated installation kit included — ships with white round grille, C-ring, and tile rails for fast deployment.

Typical Applications

• Conference room and boardroom audio systems requiring bass reinforcement
• Commercial meeting spaces and multi-purpose rooms with distributed audio
• House of worship background and fill systems integrated with Control 400 series
• Hospitality and retail environments on 70V/100V distributed systems
• Training rooms and all-hands rooms with ceiling-mounted speaker arrays

Frequently Asked Questions

Does the 419CS/T require an external crossover? No. A built-in passive low-pass filter is included, allowing the subwoofer to be connected in parallel with Control 400 full-range ceiling speakers without additional DSP or crossover hardware. External DSP is optional for 2-way active crossover configurations.

Can it be used on a 70V or 100V distributed system? Yes. The integrated 60W multitap transformer supports both 70V and 100V operation. For direct 8-ohm operation, the transformer can be bypassed.

How many units can be paralleled on one amplifier channel? In 8-ohm direct mode, two 419CS/T units can be paralleled on a single 4-ohm-rated amplifier channel for increased output and low-end extension.

Is this product plenum-rated? The 419CS/T is designed for plenum ceiling installation and ships with mounting hardware — C-ring and tile rails — suited for standard plenum ceilings. Verify local code requirements for UL plenum certifications specific to your project.

What is included with each pair? Each pair ships with two white round magnetic grilles, two C-rings, and tile rails for installation.

What full-range ceiling speakers pair with the 419CS/T? The 419CS/T is designed as a companion subwoofer to the JBL Control 400 Enhanced Coverage Series, including the Control 42C, 47C, and 47LP ceiling speakers. For system design assistance, contact Creation Networks.
