Audiocenter PRO-S5212A Dual 12" Powered PA Subwoofer
The Audiocenter PRO-S5212A is a compact dual 12" active subwoofer delivering 1500W RMS (3000W peak) through an efficient Class D amplifier, with tight, punchy bass from 32Hz to 150Hz and up to 133dB peak SPL. Its 48kHz DSP carries three presets - 80Hz, 100Hz and Cardioid - to match different venues and music styles, and dual XLR inputs with an XLR link output make it easy to run several subs together. Serious low end for live bands, DJs, clubs, corporate events and installed systems where space is limited.
Big Output from a Compact Format
Two custom 12" drivers with 2.5" voice coils move fast for tight, controlled bass, and the low-profile cabinet slots into vans, under stages and beside DJ booths where bigger boxes won't. It doesn't chase the ultra-low reach of an 18" rig - what it offers is an outstanding size-to-output ratio, with up to 133dB peak from a 41kg cabinet, running solo or arrayed for medium to large venues.
DSP Presets with Cardioid Bass Control
The onboard DSP (48kHz signal processing) switches between three tunings. The 80Hz and 100Hz presets set how the sub hands over to your top speakers, while the Cardioid preset shapes the low end directionally when multiple units are deployed together - more bass energy at the audience, less spilling back onto the stage and rear walls. That cardioid capability is the PRO-S5 series' specialty, built for portable shows, rental stock and installs that need controlled, scalable bass.
Link, Stack and Fly
Dual female XLR inputs and a male XLR link output daisy-chain signal through multiple subs and satellites without extra distribution gear. The M20-threaded pole mount socket (35mm) on the top panel takes a speaker pole, so a top speaker can sit directly above the sub in a classic sub-plus-satellite rig, and hanging installation is supported for fixed venues.
Built for the Road
The cabinet is CNC-machined wood with a durable polyurea coating and an iron mesh grille, carried by four side handles. Inside, fan plus convection cooling and an advanced driver cooling system keep temperatures in check, and a full protection suite covers DC faults, short circuits, overheating, input and output overload, soft startup, overvoltage and undervoltage. A universal 100-240V power supply with PFC handles varying venue power, and the sub sleeps automatically after 45 minutes without signal.
