Subwoofer Turbosound iQ18B Active 18", 1000W

The Turbosound iQ18B Active 18" subwoofer delivers powerful low-frequency performance with a rated 1000W of amplifier power and a purpose-built 18-inch driver. Designed for live sound and professional audio applications, this self-powered subwoofer integrates DSP-based processing to manage crossover, limiting and phase alignment for consistent and controlled bass reproduction. The cabinet is engineered for durability and transport, offering a practical solution for DJs, touring acts and installed sound systems that require deep, accurate low end.

Advantages

The iQ18B combines a high-power Class-D amplification platform with integrated DSP to provide efficient power use and protection for the loudspeaker. Its 18" transducer and optimized cabinet geometry produce extended low-frequency output with good transient response. Built-in processing simplifies system setup by providing preset crossovers and protection, while a rugged enclosure and practical handles contribute to reliable handling and on-site durability.

Suitable for

• Live concerts and club sound reinforcement
• DJ setups and mobile event production
• Theatrical and corporate AV systems requiring strong low-end support
• Installed systems in venues where compact, powered subs are preferred

Key specifications

• Driver size: 18-inch low-frequency transducer
• Amplifier output: 1000 watts (active Class-D power module)
• Integrated DSP for crossover, limiting and delay/phase control
• Input/output: balanced line-level connections and routing options

How to use

Place the iQ18B on the stage, floor or a dedicated subwoofer position, oriented according to the venue’s bass coverage needs. Connect the subwoofer to your mixing console or amplifier via the balanced line inputs and route the low-frequency content using the inboard crossover or a full-range feed depending on system configuration. Use the onboard DSP presets to match the subwoofer to your main speakers and adjust level and phase controls to integrate smoothly with the system. Ensure adequate ventilation around the amplifier section and avoid obstructing ports to maintain performance.

Использование и обслуживание

For routine operation, verify signal routing and gain structure before increasing level to prevent clipping. During transport and storage keep the cabinet dry and protected from impact; inspect connectors and handles regularly. If extended high-output use is required, monitor the DSP protection indicators and reduce input level if thermal protection engages.
