Spark CAB 2 - FAQ

Spark CAB 2 is a powered FRFR (full-range, flat-response) guitar cabinet with a 10" woofer, 2× 1" tweeters, and a 140W Class D power amp, built to pair with Spark amps and finished to match Spark 2.

Spark amps (GO, MINI, Spark 40, Spark 2) are combo units - the amp and speaker are built into one box. Spark CAB 2 is a second, larger powered speaker you connect to your Spark amp's headphone / line-out via the 3.5mm Spark Input. That gives you more volume and headroom than the amp's built-in speaker alone, in a two-piece amp-plus-cab setup.

Spark PEDAL is different - it has no built-in speaker. Spark CAB 2 becomes its dedicated speaker: connect Spark PEDAL's Line Out to Spark CAB 2's XLR/TRS Combo Input and you have a complete amp-and-cab rig in a two-piece setup.

• Spark 2 owners who want more volume / headroom and a cabinet finished to match their amp.
• Owners of other Spark amps (GO, MINI, Pedal) who want one cabinet that works with whichever Spark amp they're using.
• Owners of third-party modelers (HX Stomp, Kemper, TONEX, Helix, etc.) who need an FRFR cabinet.

Mono.

Up to 118 dB (RMS). That's loud. Think turbo-fan aircraft engine at takeoff from 200 feet.

The core hardware is unchanged - same 140W Class D amp, same 10" woofer + 2× 1" tweeter configuration, same cabinet dimensions. What's new in Spark 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 Spark CAB 2 are the retuned sound, firmware upgradeability, and matching cosmetics to Spark 2.

• Acoustics: same woofer / tweeter configuration, re-tuned voicing on Spark CAB 2 for a tighter, more defined low end.
• Firmware: Spark 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.

Spark 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.

We don't recommend it. Spark CAB 2 is FRFR - plugging a guitar straight in gives you a raw, unprocessed signal that won't sound like a usable guitar tone. Run the guitar through an amp / amp sim (Spark amp, Spark PEDAL, HX Stomp, Kemper, etc.) first, then into Spark CAB 2.

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.

The Input Selector routes either the 3.5mm Spark Input or the XLR/TRS Combo Inputs to the speaker - one source at a time. If you need to blend multiple sources, combine them first with an external mixer and feed the mixer's line-level output into Spark CAB 2's XLR/TRS Combo Input.

Yes - your Spark amp is muted by default when connected to Spark CAB 2, so all the sound comes through the cabinet.

When connecting Spark CAB 2 to Spark 2's line outputs, there is a mute / unmute switch in the settings menu in the Spark app - Spark 2 users can mute or unmute Spark 2's own 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.

No. Spark CAB 2 has no Spark app integration. All of its controls are on the rear panel. The Spark app connects to your Spark amp only.

• 1 × 3.5mm dedicated stereo Spark Input
• 2 × mono XLR/TRS combo inputs
• 1 × mono XLR balanced output (for PA / FOH)
• 1 × USB-C port (charge out + firmware update)
• 1 × DC Out (powers Spark 2 / Spark 40)
• 1 × 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.

No. The USB-C port is only for charging USB-C powered devices and for firmware updates. It isn't a USB audio interface. If you need USB audio recording, use the USB connection on your Spark amp, or feed Spark CAB 2's XLR Balanced Output into an audio interface.

No dedicated mute button. To mute the speaker, turn the Speaker Volume knob fully down. The Line Out Volume operates independently, so the XLR Output continues to work.

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.

Although the grille is removable, we are not currently providing alternatives or personalization options.

Spark CAB 2 requires AC mains power - 100-240V, 50 / 60 Hz, 250W (universal input). It cannot run on a battery or power bank.

No. Spark Battery is not compatible with Spark CAB 2. Spark Battery is designed to power Spark amps, not Spark CAB 2.

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.
