The core hardware is unchanged — same 140W Class D amp, same 10" woofer + 2x1" tweeter configuration, same cabinet dimensions. What's new in CAB 2: re-tuned acoustics, revised signal chain, and cosmetics matched to Spark 2 rather than Spark 40/GO/MINI. The reasons to move to CAB 2 are the retuned sound, firmware upgradeability, and matching cosmetics to Spark 2.

• Acoustics: same woofer/tweeter configuration, re-tuned voicing on CAB 2 for a tighter, more defined low end.
• Firmware: CAB 2 has a USB-C port for field firmware updates with an LED status indicator.
• Unchanged: power (140W RMS Class D), impedance (4 ohms), frequency range (45–20,000 Hz), dimensions, and weight are the same on both.

CAB 2's finish, color, and cosmetic details (including grill trim) are matched to Spark 2's Black/Pearl + gold trim lineup, instead of the Spark 40/GO/MINI look CAB 1 used. The cabinet shape, size, and footprint haven't changed from CAB 1.

Yes — it connects via the 3.5mm Spark Input to any current Spark amp (GO, MINI, Pedal, Spark 40, Spark 2), using the included 3.5mm stereo cable from the amp's headphone/line-out. 

Yes. Spark CAB 2 works as a general-purpose FRFR cabinet with any gear that has a line-level output — including modelers like HX Stomp, Kemper, TONEX, and Helix — via the two XLR/TRS combo inputs.

No. Traditional amp heads (tube amps and similar) aren't compatible with Spark CAB 2's inputs and could damage both pieces of equipment.

Yes. Any instrument or source with a line-level output — bass, keyboards, synths, electronic drums, etc. — can be connected through the XLR/TRS combo inputs.

No. Microphones need to go through a preamp or mixer with a line-level output first, which can then be connected to the XLR/TRS combo inputs.

Yes. Using the XLR/TRS combo inputs, Spark CAB 2 works standalone as a stage monitor or as a direct output to a PA system.

Yes — your Spark amp is muted by default when connected to Spark CAB 2, so all the sound comes through the cabinet. When connecting CAB 2 to Spark 2's line outputs, there is a mute/unmute switch in the settings menu in Spark app, Spark 2 users can mute/unmute Spark 2 speakers when using line outs with Spark CAB 2.

Yes.

• DC Out (20V/2.5A) powers a Spark 2 (using the included DC Power Cable + Spark 2 adapter) or a Spark 40 (using the DC Power Cable directly).
• USB-C Charge Out (5V/2A) charges USB-C powered amps — Spark GO, MINI, and Pedal.

• 1x 3.5mm dedicated stereo Spark Input
• 2x mono XLR/TRS combo inputs
• 1x mono XLR balanced output (for PA/FOH)
• 1x USB-C port (charge out + firmware update)
• 1x DC Out (powers Spark 2/Spark 40)
• 1x AC power input (100–240V universal)

• Input Selector — switches between the 3.5mm Spark Input and the two XLR/TRS combo inputs.
• Speaker Volume — controls overall speaker loudness.
• Line Out Volume — independently controls the XLR line-out level; doesn't affect speaker volume.
• Contour Switch — boosts low and high frequencies to improve balance at low volumes; disengage at gig volume.
• Ground Lift Switch — reduces unwanted hum or noise.
• Power Switch — turns Spark CAB 2 on/off; also cuts DC Out and USB-C Charge Out.

It's built with 2 recessed side handles for carrying, plus an adjustable cable tie on the back to secure instrument and audio cables during transport.

Black and Pearl, both matched to the Spark 2 color lineup. Both finishes use the same cabinet and acoustics — the choice is purely visual, based on which Spark 2 you're pairing it with.
