Line 6 V 412 MKII Spider Guitar Cabinet

The Line 6 Spider V 412 MkII is a purpose-built speaker cabinet housing four custom 12-inch Celestion drivers in a closed-back enclosure, designed as the matching cabinet for the Spider V 240HC MkII amp head. The custom Celestion speaker design is a key specification: Line 6 worked with Celestion to voice these drivers specifically for the Spider V's digital signal output, which covers a wider frequency range and dynamic envelope than a traditional analog guitar signal. That voicing distinction matters — a standard guitar cabinet is engineered for the frequency range and headroom of a conventional guitar amp, while the Spider V's modeled output benefits from drivers that can accurately reproduce the full character of its amp simulations without colouring them unpredictably.

Closed-back cabinet design is the right architectural choice for the Spider V system's primary use cases: rock, metal, and high-gain styles that benefit from focused low-end, midrange punch, and controlled projection. Compared to an open-back cabinet's more diffuse, room-filling character, the closed-back 4x12 plants the sound in front of the cab and projects forward — appropriate for stage reinforcement and high-SPL rehearsal. Mono and stereo inputs give the cabinet flexibility beyond the Spider V pairing, accommodating stereo effects loops, wet/dry configurations, or any amp head producing a stereo output. For full-stack players who want the visual and acoustic authority of a proper 4x12 beneath a Spider V 240HC head, this cabinet is the complete, matched solution.
