FBT PROMaxX 114A Diffusore Attivo

FBT PROMaxX 114A — Bi-Amped 14" Active PA Loudspeaker for Live Sound and DJ Use

The FBT PROMaxX 114A is a 14-inch active two-way full-range loudspeaker built for working DJs, touring bands, houses of worship and rental companies that need serious SPL from a single self-powered cabinet. Inside the polypropylene enclosure sits a custom 14" woofer with a 3" voice coil and a 1.4" B&C compression driver featuring a 2.5" voice coil, powered by a 700 W Class D low-frequency amplifier and a 200 W Class H/AB high-frequency stage. Achieve a clean 135.5 dB peak SPL across a 45 Hz to 20 kHz bandwidth, with enough headroom to cover a 150-person venue full-range or stand atop an 18" sub stack for club-level events.

What Makes the PROMaxX 114A Stand Out

Two engineering details push this cabinet ahead of typical 14"/15" active models. The DSP section is unusually deep for this price point, offering six factory presets (Original/Live, Vocal, DJ, Touring, Loudness, Warm), two user-editable slots (each with five parametric EQs), a variable high-pass filter (80–140 Hz), three-band tone section, mic/line switching, up to 3.5 m adjustable delay, and a switchable MAX-SPL/MAX-QUALITY limiter. Flexibility is further enhanced by a 90° H x 60° V constant-directivity horn and three wedge angles (12°, 40°, 55°), so it works as a front-of-house top, a stage wedge or a delay fill without re-rigging.

Power and Amplification On Stage

With a bi-amped active design, engineers can fine-tune the woofer and compression driver independently, keeping the PROMaxX 114A composed even at high volume. The Class D low-frequency amp is efficient and cool-running, while the H/AB high-frequency section maintains vocal and cymbal clarity.

• LF Amplifier: 700 W Class D RMS (1400 W peak) — delivers low-distortion power to the 14" woofer
• HF Amplifier: 200 W Class H/AB RMS (400 W peak) — maintains transient detail in the 1.4" B&C compression driver
• This model offers 135.5 dB peak SPL, providing enough output for outdoor events and medium-sized venues without needing a sub stack.

Connectivity and DSP Controls

Setting up is streamlined via a single rotary encoder with push-to-select. Access presets, EQ, delay and limiter controls without a computer. Two input paths—a balanced XLR/Jack combo for mic/line sources and a stereo RCA pair for playback—each with dedicated volume, plus an XLR link output capable of passing or mixing signals for a second speaker.

• Inputs: XLR/Jack combo + stereo RCA — compatible with microphones, instruments and playback devices
• Microphone Input: Yes (mic/line selector on XLR) — allows direct connection for MCs and presenters
• Link Output: XLR male (link or mixed) — chain a second speaker without using a separate mixer
• The built-in DSP includes a three-band EQ, six factory presets and two user slots for tailoring sound to vocals, DJ sets, live bands or background music.

Cabinet Construction and Mounting Options

The molded polypropylene housing keeps weight at 17.5 kg. There are two integrated handles, a 35 mm pole socket for mounting, M10 suspension points for flying, and a wall bracket flange plate. The full-front grille design protects the drivers while keeping high frequencies open.

• Frequency Range: 45 Hz – 20 kHz — supports full-range applications and pairs with an 18" subwoofer
• Standard 35 mm top-hat socket fits tripod and distance-rod speaker stands
• Dispersion: 90° H x 60° V — covers small audiences while focusing sound on the dance floor
• Dimensions: 402 x 644 x 345 mm — compact enough to fit a standard van loadout

Who Uses the PROMaxX 114A

This model is designed for mobile DJs, live-sound providers and AV rental firms seeking a single powered top that can handle a 150-person event full-range or act as a club-top above subs for 400-plus events. Solo acts and duos appreciate the vocal preset and mic/line input, while school AV teams and worship venues benefit from easy room-tuning and wall-mount options. Touring bands with subs will value the 135.5 dB headroom and a preset voiced to match large-format touring rigs.
