K-Array Vyper KV52R II – In-Wall Recessed Line Array

Product Overview

The K-Array Vyper KV52R II is an in-wall line array speaker engineered for recessed architectural installations where the loudspeaker must sit flush with the wall surface. Eight 1-inch neodymium magnet drivers housed in a sturdy aluminum chassis with a complete frame and clamps deliver 114 dB peak SPL with 10° vertical by 140° horizontal coverage, making it a flush-mount speaker for boardrooms, conference rooms, and discreet distributed audio systems. Selectable 16-ohm or 64-ohm impedance allows up to sixteen elements per 4-ohm amplifier channel without 70V lines. Browse the full lineup in the K-Array collection.

Product Description

The KV52R II is the recessed in-wall version of K-Array's half-meter Vyper II element. Its aluminum chassis is designed specifically for in-wall recessed installations: the integrated frame and clamps secure the element flush into drywall or millwork, leaving only a slim 50 mm wide grille visible. The eight closely spaced 1-inch neodymium cone drivers provide true line array characteristics — phase coherence, low distortion, and focused listening in both the near field and at distance — across 150 Hz to 18 kHz for articulate speech and program audio. The tight 10° vertical beam keeps energy on the audience and off reflective ceilings and floors, while the 140° horizontal pattern covers broad rooms from a single recessed element. Selectable 16/64-ohm impedance allows up to sixteen KV52 II loudspeakers on one 4-ohm amplifier channel at 64 ohms, eliminating 70V lines in wide distributed systems where intelligibility and elegance are both mandatory. Two-pin Euroblock connectors are included, IP65 construction supports indoor and outdoor installations, and dedicated factory presets optimize performance on K-Array amplifiers. For surface mounting instead of recessing, see the Vyper KV52 II; a white recessed version is available as the Vyper KV52RW II.

Key Features

Typical Applications

• Boardrooms and conference rooms requiring program audio with no visible loudspeaker hardware
• House of worship sanctuaries and heritage interiors where equipment must stay invisible
• Government spaces such as chambers and hearing rooms with strict aesthetic requirements
• Commercial meeting spaces and multi-purpose rooms using flush distributed audio
• Training rooms and all-hands rooms with recessed speech reinforcement

Technical Specifications

Frequently Asked Questions

What amplifier should power the Vyper KV52R II?

The KV52R II is a passive loudspeaker with selectable 16/64-ohm impedance. Dedicated factory presets optimize performance on K-Array amplifiers, but any professional installation amplifier with appropriate power and DSP can drive it. At 64 ohms, up to sixteen elements can share one 4-ohm amplifier channel.

What is included for in-wall installation?

The KV52R II ships with its complete recessed mounting frame, clamps, and a 2-pin Euroblock connector. K-Array also publishes a drilling template for accurate cut-outs in drywall and millwork.

How is the KV52R II different from the KV52 II?

The KV52 II is the frameless surface-mount version; the KV52R II adds a frame and clamps for recessed in-wall mounting. Acoustic performance is the same.

Does the KV52R II need a subwoofer?

For speech, the element covers the vocal range from 150 Hz with high intelligibility on its own. For full-range music programs, K-Array recommends pairing it with a compact subwoofer.

Can it be installed outdoors?

Yes. The KV52R II is IP65 rated and suitable for indoor and outdoor installations.

What warranty applies to this product?

K-Array provides a 5-year manufacturer warranty, supported by Creation Networks as an authorized dealer. See the full range in our K-Array collection.
