HL1650 6.5" Passive Line Array Speaker

The HL1650 6.5-inch passive line array speaker is a professional loudspeaker designed for medium-sized live events, churches, conference halls and fixed installations where higher output and longer sound projection are required.

Featuring a 6.5-inch low-frequency driver, a 1.4-inch compression driver and precision horn, the HL1650 delivers clear vocals, balanced music reproduction and controlled sound dispersion across large audience areas.

When combined with the HL112BA active subwoofer, the system becomes a compact yet powerful professional line array solution suitable for concerts, worship services, conferences and touring productions.

Professional Line Array Design

Unlike traditional point-source loudspeakers, the HL1650 is engineered as a modular line array cabinet.

Multiple cabinets can be connected vertically to create a scalable sound reinforcement system offering:

• Consistent sound pressure throughout the audience

• Excellent speech intelligibility

• Controlled vertical directivity

• Wide horizontal audience coverage

• Reduced front-to-back SPL variation

• Flexible system expansion

Additional line array models can be found in our Line Array Speakers collection.

Adjustable Flying System

The HL1650 uses dedicated flying hardware designed for fast, safe and reliable installation.

Each cabinet can be adjusted between:

0°–12°

with 1° angle increments, allowing installers to build the ideal line array curvature according to:

• Audience depth

• Ceiling height

• Venue geometry

• Installation position

• Number of cabinets

• Required coverage area

Excellent Sound Performance

The HL1650 offers:

• Frequency Response: 65 Hz–20 kHz

• Sensitivity: 97 dB

• Nominal Dispersion: 100° × 10°

Its wider low-frequency response and larger driver provide stronger vocal presence and improved music reproduction compared with compact dual 4-inch systems.

The 1.4-inch compression driver also delivers smooth high frequencies with excellent clarity for speeches, vocals and live performances.

HL112BA Active Subwoofer Integration

The HL1650 is designed to operate together with the HL112BA Active Subwoofer.

The HL112BA integrates:

• 12-inch high-power subwoofer

• Built-in DSP processor

• Dual-channel power amplifier

• Active crossover

• Digital signal processing

• System protection

• Frequency optimization

The DSP processes the input signal before distributing it to the subwoofer and line array cabinets, producing a balanced full-range sound system.

More low-frequency solutions are available in our Subwoofers category.

DSP-Controlled Professional Audio System

When used with the HL112BA, the audio signal follows the system workflow:

Audio Source → DSP Processing → Digital Crossover → Power Amplifier → Subwoofer + Line Array Output

The integrated DSP provides:

• Electronic crossover

• Equalization

• Delay adjustment

• Speaker protection

• Output balancing

• System optimization
