Turbosound iQ15 Active Loudspeaker

2,500-Watt Powered 15" Loudspeaker for Portable PA and Installation

The Turbosound iQ15 is a powered two-way loudspeaker for portable PA rigs, mobile DJs, houses of worship, and fixed installations. A 15" low-frequency driver with a low-mass voice coil pairs with a high-temperature 1" compression driver to reproduce the full musical spectrum. A 2,500-Watt Klark Teknik Class-D amplifier drives both drivers, giving the cabinet enough headroom to fill medium and large rooms. This model is the right choice for working musicians who need a self-contained box that moves easily from a 300-seat hall to an outdoor stage.

Klark Teknik DSP, Ultranet, and Smart Connectivity

What sets this model apart is the depth of its onboard processing and networking. Klark Teknik DSP provides dynamic EQ, transparent limiting at high output, and a library of speaker emulations that recreate the character of classic studio monitors. SCC (Spatial Contour Control) compensates the frequency response based on whether the cabinet is pole-mounted, wall-mounted, or used as a floor wedge. Ultranet streams up to 16 channels of digital audio over a single Cat-5 cable from a compatible digital mixer.

Key Technical Parameters

• Maximum SPL: 132 dB peak — enough clean volume for audiences of several hundred.
• Drivers: 15" LF + 1" HF compression driver — tight low end with clean extended highs.
• Inputs: 2 x Combo XLR/Jack, USB-B, Ethernet (Ultranet) — mic/line and digital audio sources.

Who This Powered Speaker Is For

The iQ15 is the right choice for solo performers, duos, small bands, mobile DJs, and AV rental companies that need a single powered speaker for vocals, instruments, and playback at gig-level volume. Front-of-house engineers appreciate the on-board DSP and Ultranet because they can tune the system and route audio from a digital mixer with a single Cat-5 cable. The 36 mm pole mount and M10 rigging points allow for permanent installation.
