Sound Town ZETHUS Series A26X4F Powered Line Array System
The ZS-A26X4F set includes four ZETHUS-A26PW powered line array speakers and a ZETHU-A26FF flying frame, delivering a complete all-in-one line array solution. Each powered speaker uses dual 6.5″ woofers and a 1 3/8″ titanium compression driver, powered by a two-channel class-D amplifier. It yields 300W continuous and 600W peak per speaker, with a symmetrical design for flexible configurations. Onboard DSP provides four preset modes for tailored sound, plus high-frequency adjustments and a waveguide for consistent coverage. This system is best for mid-sized venues, corporate events, and live performances where precise control and quick setup matter. A limitation to note: detailed field testing may be required to optimize DSP presets in unusually shaped rooms.
Sound Town ZETHUS Series 115SPW205V2X4 System
This configuration centers on a 15″ powered subwoofer paired with four compact passive line array speakers. The subwoofer handles 600W continuous and 1200W peak, with a switchable low-pass filter (40Hz–180Hz) and DSP-based enhancements for deep, controlled bass. The four 5″ passive line array speakers provide 200W RMS and 400W program power, with full-range bi-amp capability for flexible system tuning. This setup is ideal for venues that require solid low-end reinforcement with a lighter, scalable array. Consider this option if you prioritise robust bass without carrying overly large active tops.
Sound Town CARPO-LA62F Line Array System
The CARPO-LA62F pair includes one powered 6.5″ LA speaker and one passive 6.5″ LA speaker plus a flying frame, offering a compact, portable line array setup. The powered unit uses dual 6.5″ woofers and two 1″ titanium compression drivers, delivering 240W continuous and 480W peak with an efficient 2-channel class-D amplifier. The passive partner matches at 240W RMS/480W program, designed for bi-amp operation if paired with a suitable external amp. This is a strong choice for small venues, mobile DJs, or installations needing a simple, transport-friendly solution. Limitation: fewer channels and built-in DSP features compared to larger systems.
Sound Town ZETHUS 115SPW208X2 System
This system combines a 15″ powered sub with two 8″ passive line array speakers, forming a full-range configuration with bi-amp capability. The sub delivers 600W continuous and 1200W peak, with DSP-based low-pass control and four digital EQ presets for precise bass shaping. The two 8″ passives offer 350W RMS and 700W program, providing broad coverage with clear mids and highs. Best for medium rooms requiring strong bass, consistent coverage, and flexible stage monitoring. A potential drawback is the need for external amplification if expanding beyond the two passive boxes.
JBL IRX ONE Active Powered Column System
JBL IRX ONE is an active powered column system designed for quick setup and even throw. It delivers 1300W peak power total with a slender column array for uniform coverage and reduced feedback. The system includes a built-in 3-channel mixer and supports Bluetooth connectivity for wireless playback, making it suitable for mobile DJs, small venues, or speakers who require fast deployment without sacrificing clarity. Choose this if portability and fast setup are top priorities; opt for a larger, more traditional line array if you require deeper bass for larger spaces.
Buying Guide
- Venue size and coverage. Larger rooms benefit from bigger subs and more efficient line arrays; smaller spaces may prioritize portability and quick setup.
- Power and headroom. Look for systems with adequate continuous power and peak headroom to avoid distortion in loud passages.
- Bi-amp capability. If you plan to fine-tune high and low ranges separately, bi-amp support adds flexibility.
- DSP and presets. Onboard DSP helps tailor response to room acoustics; consider presets for vocal clarity, music, and live bands.
- Portability. Flying frames and compact passive tops reduce transport effort. For touring, lighter systems with quick setup are advantageous.
- Expansion options. Modular subs or additional passive tops enable future scaling to larger venues.
FAQ
- What is a powered line array system? A system where the speaker cabinets include built-in amplifiers, reducing external components and simplifying setup.
- How many speakers do I need for a medium venue? A typical arrangement uses several powered tops plus a sub or two; the exact number depends on room size, audience, and SPL requirements.
- Should I choose a subwoofer with the line array? Yes, subs extend low-frequency impact and balance the mid/high range for full-range coverage.
- Is bi-amping necessary? Not always, but it provides more precise control over different frequency bands, which is helpful in acoustically challenging rooms.
- Which system is most portable? Systems with one powered top and a short flying frame or compact column designs are typically easiest to transport.
- Do DSP presets replace a soundcheck? DSP presets assist tuning but still require room-aware adjustments during a soundcheck for optimal results.
