The Turbosound TPZ153/64 is a switchable passive / bi-amp arrayable 3-way 15" full-range zone-fill loudspeaker with tight 60° horizontal by 40° vertical dispersion, engineered for permanent installations where the brief calls for higher SPL, better mid-band clarity and longer throw than 2-way zone-fill cabinets can deliver.

Why 3-way zone-fill

Splitting the audio band across three dedicated drivers — LF, MF and HF — rather than two reduces distortion in the crossover region and improves vocal intelligibility in the critical 1–5 kHz band. For zone-fill duty in larger worship venues, performance halls and high-ceilinged commercial spaces where the audience plane sits at extended throw from the fill position, the 3-way TPZ153/64 delivers the detail that 2-way alternatives compromise.

Engineering highlights

• 15" LF driver, dedicated MF driver and HF compression driver in a 3-way configuration
• 60° H x 40° V rotatable waveguide for landscape or portrait orientation
• Switchable passive (single amplifier channel) or bi-amp / tri-amp (external processing) operation
• Birch-plywood cabinet with multiple M10 rigging points for permanent flown installation
• Neutrik speakON® NL4 connectors plus barrier strip for distributed wiring

Specify as the high-output zone-fill or delay cabinet in larger Prague-series fixed installs, time-aligned with TPA152 or TPA152/95 main tops for tonally-matched extended coverage.
