Key Features & Benefits

Rich Dual-Speaker Tone
The two 12″ Zephyr speakers provide full, dynamic sound suitable for a wide range of genres from blues and rock to heavier styles. The 140 W power rating ensures clarity and headroom even at higher volumes.

Flexible Acoustic Character
The removable back panel lets you choose between focused projection for stage use (closed-back) or broader, open sound for rehearsal or ambient playing (open-back).

Lightweight and Gig-Friendly
Constructed from durable candlenut plywood, the cabinet is significantly lighter than traditional 2×12 cabs while maintaining robust tonal output, making it ideal for transport and stage use.

Versatile Compatibility
Mono operation with selectable impedance allows it to pair with a variety of tube and solid-state amp heads, giving flexibility in different rig setups.
