Positive Grid Spark CAB 2 Black — 140W FRFR Power for Spark and Beyond

The Spark CAB 2 is a 140W powered FRFR (full-range, flat-response) speaker cabinet built to turn any Spark amp into a full performance rig. A 10" woofer paired with dual 1" tweeters reproduces modeler and IR-based tones without adding coloration, so what you hear on stage matches what you dialed in at home. Re-tuned acoustics and an upgraded signal path keep the cabinet composed at any volume, from bedroom practice to band rehearsal. Finished in black with gold trim to match the Spark 2 combo amp, it creates a unified look when stacked together.

What Sets This Cabinet Apart

Two features make this model stand out in the FRFR category. First, the integrated power hub: a DC output (20V/2.5A) powers a Spark 2 or Spark 40, while a USB-C output (5V/2A) charges a Spark MINI, GO, or PEDAL — one wall outlet runs the whole rig. Second, the independent volume architecture: a Speaker Volume knob controls local stage volume while a separate Line Out Volume sets the level sent to the front-of-house PA via the balanced XLR output, so the player and the sound engineer each get their own mix.

Power and Speaker Configuration

The 140W Class D amplifier delivers clean headroom for live performance, with 400W of peak power available for transient response. A 10" woofer handles the low end down to 45 Hz, while dual 1" tweeters carry the high frequencies up to 20 kHz — a configuration that mirrors a nearfield studio monitor more than a traditional guitar cab.

• Power Output: 140 W RMS / 400 W peak — Class D topology keeps weight and heat low while leaving headroom for clean, uncompressed transients
• Speaker Configuration: 1x 10" woofer + 2x 1" tweeters — three-way coverage that reproduces both bass response and high-frequency detail from amp simulations
• Frequency Response: 45 Hz – 20 kHz — full-range coverage that lets acoustic, electric, and bass sources all sit in the mix

Cabinet Construction and Acoustic Tuning

The bass-reflex wood enclosure is the foundation of the cabinet's sound. Positive Grid re-tuned the internal acoustics for this generation, delivering a tighter low end and clearer midrange than the original Spark CAB. The woven grille cloth and recessed side handles complete a road-ready package at 13.5 kg.

• Cabinet Principle: Bass reflex — ported design extends low-frequency response and improves transient punch
• Cabinet Material: Wood — rigid enclosure reduces unwanted resonance and coloration
• Max SPL: 118 dB RMS / 121 dB peak — enough output for small-to-medium venue gigs without compression

Inputs, Outputs, and Onboard Controls

Connectivity is where this cabinet earns its "rig expander" name. A dedicated 3.5mm stereo input accepts any Spark amp's line output, while two XLR/TRS combo jacks handle modelers, multi-effects units, and line-level instruments. A balanced XLR output sends signal to the PA, and the rear panel adds a Contour switch for low-volume tone shaping plus a Ground Lift to kill hum.

• Inputs: 1x 3.5mm stereo Spark input + 2x XLR/TRS combo — covers Spark amps, HX Stomp, Kemper, TONEX, Helix, and any line-level source
• Output: 1x balanced XLR with independent Line Out Volume — feeds the front-of-house mix without affecting stage volume
• Power Outputs: DC 20V/2.5A (Spark 2/Spark 40) + USB-C 5V/2A (Spark MINI/GO/PEDAL) — one AC outlet powers and charges the entire Spark ecosystem

Who Should Choose the Spark CAB 2

The Spark CAB 2 is the right choice for Spark amp owners who need more volume and headroom than the combo's built-in speaker can deliver, and for modeler players who want a single cabinet that works across their whole rig. It suits home players who want a full-range cab for practice, rehearsal-room players who need enough SPL for a five-piece band, and gigging guitarists who run HX Stomp, Kemper, TONEX, or Helix and need a transparent stage monitor. Bass and keyboard players with line-level outputs can also use it as a compact stage monitor. Players using traditional tube amp heads should look elsewhere — the inputs are line-level only and are not designed for speaker-output connections.
