Positive Grid retunes Spark CAB 2 for tighter lows and a cleaner path into modeler rigs
The 140-watt powered FRFR cabinet keeps the 10-inch-plus-tweeter format while adding revised acoustics, flexible power and independent stage and PA levels.

Positive Grid’s Spark CAB 2 is a second-generation powered full-range cabinet built for the Spark amp family and for other modelers, pedals and line-level guitar rigs. Its basic architecture remains a 10-inch woofer with two one-inch tweeters driven by 140 watts RMS, but the enclosure has been retuned for greater detail and a tighter low end, with revised conversion and gain staging intended to produce a cleaner signal path.
A dedicated Spark input connects the company’s amps and Spark PEDAL, while two XLR/TRS combo inputs accept stereo line-level sources from other manufacturers. A balanced XLR output can feed a front-of-house system while the cabinet continues to work as a personal monitor. Separate speaker and line-output level controls let the player adjust stage volume without changing the signal sent to the PA.
The cabinet also acts as a power hub. Its DC output supports Spark 40 and Spark 2, while USB-C can power or charge Spark MINI, GO and PEDAL and is used for firmware updates. A contour control lifts lows and highs for lower-volume use, and a ground-lift option is included for hum management. Positive Grid offers the cabinet in Black and Pearl finishes.
The practical change is less about headline wattage than about making one box serve at home, in rehearsal and on stage. The revised low-frequency voicing directly addresses the bass-heavy character noted in reviews of the original Spark CAB, while the stereo inputs and independently controlled PA feed keep the cabinet useful beyond Positive Grid’s own ecosystem.

Why it matters
Modeler users increasingly need one cabinet that can cover practice, monitoring and front-of-house routing; Spark CAB 2 targets that workflow while addressing the original cabinet’s most consistent tonal criticism.
