HK Audio Linear 3 112 FA 12in/1in Full Range Mid/High Speaker

This second hand PA speaker is in great condition

Includes carry bag

The HK Audio Linear 3 112 FA sits in a sweet spot between portability, power, and sound quality. It’s designed for performers who want a professional‑grade active speaker without the weight, bulk, or price tag of a full touring cabinet. As part of the Linear 3 family, it brings HK’s signature clarity and punch, but with a more modern tuning and higher output than the older Premium Pro series.

 Sound Quality

The 112 FA uses a 12" woofer paired with a 1" driver, powered by a 1200W Class‑D amplifier. In practice, that translates to:

• Clean, articulate mids, vocals, guitars, and keys sit forward without harshness
• Surprisingly deep low‑end for a 12", especially in “Bass Boost” mode
• Smooth, controlled highs that avoid the brittle edge some plastic‑cabinet speakers suffer from
• Max SPL around 135 dB, giving it enough headroom for small to medium gigs

HK’s DSP presets are genuinely useful rather than gimmicky. “Flat” is neutral and accurate, “Bass Boost” adds warmth for DJs or playback, and “Contour” gives a smile‑curve EQ that works well for live bands.

Features & Connectivity

The Linear 3 112 FA is built with working musicians in mind. Key features include:

• 2‑channel input section with XLR/jack combo sockets
• Mix output for daisy‑chaining
• Four DSP presets (Flat, Boost, Contour, Speech)
• HK’s FIR‑based tuning for improved phase coherence
• M10 rigging points and a dual‑tilt pole mount (0° / 7.5°)

The DSP is simple, no menus, no screens, no over‑complication. Just a few switches that make a noticeable difference.

 Build Quality & Portability

HK Audio’s build quality is consistently excellent, and the 112 FA continues that trend:

• Birch plywood cabinet with a tough textured finish
• Solid steel grille
• Ergonomic MultiGrip handles
• Weight around 20 kg, making it manageable for one person

The 112 FA shines in:

• Live bands—great vocal clarity and midrange definition
• DJs—tight low‑end and high output, especially when paired with an HK sub
• Corporate / speech—the “Speech” preset is crisp and highly intelligible
• Small to medium venues—pubs, clubs, function rooms, and outdoor events

Pairing it with the LSUB1500A creates a powerful, musical, and scalable system.

Pros

• Excellent clarity and vocal presence
• Strong output for a 12" cabinet
• Useful DSP presets
• Rugged wooden construction
• Easy to transport and set up

The HK Audio Linear 3 112 FA is a superb all‑rounder for musicians, DJs, and small PA providers who want professional sound quality without the complexity or bulk of higher‑end touring systems. It’s clean, powerful, and built to last, with DSP presets that genuinely enhance real‑world performance.
