Features

• 3,000-Watt Power Output: The Turbosound iQ15B delivers an impressive 3,000 watts of power through Klark Teknik’s Class-D amplifier technology. This ensures high efficiency, strong output, and reliable performance for demanding environments.
• Klark Teknik DSP Technology: The integrated Digital Signal Processor (DSP) offers precise control over the system, including dynamic EQ, transparent limiting, and speaker modeling presets. These presets accurately emulate industry-standard speakers, providing flexibility for various audio setups.
• 15″ High-Excursion Low-Frequency Driver: The iQ15B is equipped with a 15″ driver with a 4″ voice coil, allowing for fast transient response and deep, distortion-free bass, even at high volumes.
• ULTRANET Digital Audio Networking: The ULTRANET system uses CAT5 cables to transmit pristine multi-channel audio signals between ULTRANET-enabled devices, such as digital mixers and powered speakers. This technology reduces setup time and eliminates interference common with analog connections.
• USB Remote Control and Firmware Updates: A USB port provides convenient access for remote control of DSP settings via a PC or Mac. It also supports firmware updates, ensuring the subwoofer stays up to date with the latest features and improvements.
• Durable Birch Plywood Enclosure: The iQ15B’s birch plywood construction, finished in semi-matt black, ensures maximum durability in both portable and installed setups. The powder-coated perforated steel grille protects the internal components during transport and use.
• Integrated 36mm Pole Mount: A 36mm pole mount allows the iQ15B to support a satellite speaker, making it easy to integrate into a full-range sound system.
• Plated Steel Castors: The subwoofer is equipped with plated steel castors with rubber tires, providing smooth mobility and easy transport during setup and breakdown.
