What is the L-Acoustics KUDO?

The KUDO is a 3-way, quad-amplified line source speaker that integrates advanced driver design with innovative acoustic control. Unlike many conventional systems, KUDO provides flexible horizontal coverage—making it highly adaptable to different venue shapes and audience configurations.

The Technology Behind L-Acoustics Line Source Systems

L-Acoustics pioneered the concept of WST® (Wavefront Sculpture Technology), which ensures consistent sound distribution and phase coherence. With KUDO, WST is applied in both vertical and horizontal planes, creating a true multi-directional line source system.

The DOSC® waveguide technology in the HF section ensures pristine high-frequency response and smooth transitions across coverage angles.

How KUDO Differs from Other L-Acoustics Models

• Compared to V-DOSC, KUDO offers horizontal coverage.

• Compared to ARCS, KUDO provides higher SPL output and extended frequency range.

• KUDO bridges the gap between flexible touring systems and permanent installations, making it a versatile choice for rental companies and venues alike.

Key Features of the L-Acoustics KUDO

Adjustable Horizontal Coverage with K-Louvers

The standout feature of KUDO is the K-Louver system, which allows engineers to mechanically adjust horizontal coverage. Options include:

• Symmetric: 50° or 110°

• Asymmetric: 25°/55° or 55°/25°

This flexibility reduces unwanted reflections and ensures even coverage across complex audience areas.

Wavefront Sculpture Technology (WST)

By applying WST principles, KUDO achieves:

• Minimal distortion and phase shift

• Smooth, coherent wavefronts

• Better intelligibility over long distances

---

Rigging and Array Flexibility

• Up to 21 KUDO elements can be flown vertically with 0° to 10° inter-element angles.

• Horizontal arrays of up to 6 elements can be built using the K-LIFT system.

• Integrated captive rigging ensures quick deployment and safe operation.

L-Acoustics KUDO vs. Competitors

Comparison with JBL VTX and Meyer Sound MICA

• JBL VTX: Known for raw power, but less flexible in horizontal coverage.

• Meyer Sound MICA: Offers excellent sound quality, but requires more elements for similar SPL.

• KUDO: Balances power and flexibility, reducing the number of boxes needed.

---

KUDO vs. L-Acoustics V-DOSC and ARCS

• V-DOSC: Pioneering line array, but lacks adjustable directivity.

• ARCS: Compact and versatile, but not as powerful for large-scale venues.

• KUDO: Combines both strengths—power, flexibility, and scalability.

---

Pricing and Availability

New vs. Used Market Pricing

• New: Pricing varies but generally falls around $12,000–$15,000 per cabinet.

• Used: Depending on condition, prices range from $5,000–$8,000 per cabinet.

FAQs About L-Acoustics KUDO

1. Does the L-Acoustics KUDO require subwoofers?
It performs well down to 35 Hz, but for deep bass, pairing with SB18 or SB28 subs is recommended.

2. Can the KUDO be flown both vertically and horizontally?
Yes. It supports vertical arrays of up to 21 boxes and horizontal arrays of up to 6.

3. What is the advantage of K-Louvers?
They allow adjustable horizontal coverage, reducing unwanted reflections and tailoring dispersion to different venues.

4. How does KUDO compare to modern L-Acoustics systems like K2 or K1?
K2 and K1 offer newer technology and lighter weight. However, KUDO remains a cost-effective and powerful solution still used worldwide.

5. Is the KUDO suitable for small venues?
No. It is designed for medium-to-large venues and would be overkill for small clubs or studios.

6. What amplifier is best for KUDO?
L-Acoustics recommends the LA8 amplified controller, which provides presets, DSP, and protection.
