← Back to Subwoofer SeriesX182A
Single 18-inch powered subwoofer with a complete amplifier inside: 600 W to its own driver, plus 400 W a side of powered speaker output for left and right. The satellites run from the subwoofer, so a full system needs one powered box and no amplifier rack. Rated to 128 dB maximum SPL, flat to 30 Hz within ±3 dB and reaching 22 Hz within ±10 dB, with full DSP control from XSCACE Studio through an externally-mounted interface module — and the cabinet is rated IP55 and ships with a weather cover, so it stays outdoors permanently.

Technical Specifications
Frequency Response & Directivity
Set up in XSCACE Studio
DSP control, intelligent room correction and a full professional calibration suite. Every parameter on this powered subwoofer — levels, delay, crossovers, limiter and EQ — opens in the same application that configures the rest of the range, so an installer learns one tool.
Live DSP Control
Connect to any Xylem on the network and the full signal chain opens up: per-channel gain and delay, four crossover modes with live curve rendering, and six bands of parametric EQ per channel. Changes hit the DSP instantly over the local network — no round trips, no cloud. Discovery is zero-configuration: amplifiers announce themselves, so there is nothing to pair and no address to type. The delay block itself is accurate to 3 µs on a commanded 5.000 ms.
A Preset for Every XSCACE Speaker — and Yours
Connect a Cane, a Bonsai, a QuadCane, and the amplifier lists an XSCACE factory preset for that speaker: crossover, EQ and limiter threshold already set from the model's real driver and power handling. Load it and the zone is playing correctly before anything has been measured. Tune further from there, then save the result under your own name — the next identical zone in the project starts from a proven configuration instead of the factory default.
One Number, Not Thirty-Four
Per-channel limiting built on a peak-and-RMS combo: a 34-point gain transfer curve plus five time constants. You set one value — threshold in dBFS — because that is the number printed on the driver's datasheet and therefore the one an installer actually has. The device generates the curve from it, and the app states the consequence in plain language: at −6 dBFS, output is held there and peaks above it are caught in about 2 ms. Peak and RMS detectors run in parallel and whichever asks for more reduction wins. 33 factory presets across the range ship with thresholds derived from each speaker model's real power handling; an amplifier lists the presets matching its own channel count.
PsySculpt Low Extension
A per-input side-chain that synthesises harmonics of fundamentals the cabinet cannot physically reproduce, so the ear infers a fundamental that is not being played — the usable low end reads about an octave below the driver's rated limit. A Cane rated to 150 Hz reads to about 75 Hz; a Bonsai rated to 300 Hz to about 150 Hz. It is not a bass boost — nothing below the driver's range is amplified, because there is nothing there to amplify. The control reads "extend down to X Hz" because it sets how deep the effect reaches rather than naming a filter, with an extension target down to 40 Hz and settings that ride along with system presets.

Built to work together
The back panel, explained
Everything the system needs is on one plate: the signal in, the processing, the levels, the two powered outputs that drive the satellites, and mains that loops on to the next cabinet.
- 1
32-bit DSP and presets
The processing display and preset selector. Presets recall from the panel itself, so a system can be switched without a laptop or a tablet on site.
- 2
Two XLR pre-level inputs
IN A / MONO IN and IN B take a line-level feed, with a mono A+B switch for running the pair from a single source. Each has a male XLR link output to pass the signal on to the next subwoofer in a stack.
- 3
RS485 and USB
RS485 in and link for control across multiple cabinets, and USB for direct connection. The externally-mounted interface module bridges these to XSCACE Studio.
- 4
Full-range and bass volume
Two independent level controls: one for the satellites on the powered outputs, one for the subwoofer's own driver. Balance is set on the box, not upstream.
- 5
Cast heatsink
The finned casting is the amplifier's entire cooling system. No fan means no intake, which is part of how the cabinet stays sealed against weather.
- 6
Two 400 W speaker outputs
OUT 1 and OUT 2 on speakON, 400 W each, wired 1+ / 1-. The left and right satellites connect here and run from this amplifier — the reason a full system needs no separate amplifier rack.
- 7
AC in and AC through
powerCON input and a powerCON output on the same panel, so mains loops from one cabinet to the next rather than running a separate feed to each.

Frequently asked questions11 answers
What is the XSCACE X182A?
Specified for outdoor venues, terraces, poolside and garden installations, festival and event stages, and large public spaces where a powered subwoofer has to drive the satellites itself and survive weather exposure without a dry amplifier position.
What is the frequency response of the X182A?
The X182A covers 30Hz–200Hz (±3dB).
What is the power output of the X182A?
The X182A is rated at 600W RMS into 8Ω.
What type of product is the X182A?
The X182A is a subwoofer product.
What DSP does the X182A use?
32-bit processing with on-panel preset recall; full parameter access through XSCACE Studio via the supplied interface module. Every crossover, EQ band, delay and limiter runs on that processor and is set from XSCACE Studio over the network; the configuration is stored on the amplifier itself.
What does PsySculpt do on the X182A?
PsySculpt is equal-loudness compensation running continuously on the DSP. A log-decay peak detector tracks programme level and drives low and high shelving filters from it, so perceived tonal balance stays constant as volume changes, with a level-tracked bass stage and a hard ceiling before the converters. It is not room correction — room correction is measured and applied in XSCACE Studio.
Do the X182A settings survive a power cut?
Yes. Gain, EQ, crossover, delay and limiter settings are held in non-volatile memory on the amplifier, so it returns to the configured state after any power event or firmware update.
How much space does the X182A need?
The chassis is 739 mm high, 624 mm wide and 806 mm deep. Ground stack. Place against a boundary where possible — a wall or a corner behind the cabinet adds output below 60 Hz at no power cost.
How deep is the X182A?
The X182A requires 806mm of depth.
Is the X182A rated for outdoor or wet-area use?
Yes, the X182A carries an IP55 ingress protection rating.
What is the X182A typically used for?
The X182A is typically specified for Outdoor terraces and poolside · Garden and rooftop events · Festival and event stages · Resort and hospitality grounds · Sports and public address.
