The image shows the rear input and jack plate of a Line 6 Spider 4x12 Guitar Speaker Cabinet (commonly paired with Line 6 stereo modeling amplifier heads like the Spider III HD150 or Spider IV HD150).

Key Specifications

• Cabinet Type: 4x12 Closed-Back Guitar Enclosure (available in slant or straight versions)
• Speakers: Four 12-inch custom-voiced Celestion drivers
• Impedance & Wiring Options:
• • Stereo Mode: 8 ohms Left / 8 ohms Right (handling up to 150 Watts maximum per side)
  • Mono Mode: 4 ohms total impedance (using the dedicated mono jack)
• Hardware & Construction: Rugged wood-ply cabinet wrapped in black Tolex, featuring heavy-duty recessed side handles and a closed-back design for deep low-end projection..

Pros & Performance Notes

• True Stereo Integration: If you use a stereo modeling amp or effects processor, this cab allows you to run true left/right stereo separation (such as ping-pong delays and wide stereo choruses) straight out of a single enclosure.
• Massive Value: It is one of the most cost-effective ways to get a loud, gig-ready 4x12 half-stack setup for rehearsal or stage use.
• The Catch: Like all standard 4x12 cabinets, it is heavy and cumbersome to transport, which is why secondhand deals almost always require local pickup.
