Positive Grid has released the Spark CAB 2, a guitar amplifier cabinet designed to resolve the excessive bass response of its 2023 predecessor. The unit is currently available for purchase at $399.
Why it matters
This release directly addresses acoustic frequency balancing in the company's portable amp ecosystem, prioritizing signal clarity over the low-end heaviness of the previous model.
The Spark CAB 2 delivers 140 watts through a 10-inch woofer and two 1-inch tweeters. This configuration is an update to the 2023 original, specifically engineered to mitigate low-frequency output issues.
The players
Positive Grid
A developer of digital guitar amplifiers, software modeling plugins, and guitar-focused hardware.
The details
The Spark CAB 2 achieves its cleaner sound profile through revised gain staging—the process of managing the signal level through different stages of a circuit to maximize signal-to-noise ratio. Engineers also adjusted the conversion stage, which translates digital audio signals into analog sound. These changes, paired with the 10-inch woofer and two 1-inch tweeters, are aimed at improving detail and clarity across the frequency spectrum.
Timeline
The original Spark CAB launched in 2023.
Positive Grid released the Spark CAB 2 in October 2026.
The Tech Race
The Spark CAB 2 follows the 2023 Positive Grid Spark CAB, serving as a refinement of the company's existing amplifier hardware line. It focuses on corrective acoustic tuning rather than replacing the broader product roadmap.
The unit is available immediately in Black and Pearl colorways for $399. Users of the Spark 40 or Spark 2 models can utilize the device's DC output for integrated power support.
The takeaway
The Spark CAB 2 demonstrates that the company is prioritizing acoustic resolution in its latest hardware revision. Owners of existing Spark units should monitor for future firmware updates that may optimize interaction with the new cabinet's revised gain staging.
