This full-stack guitar cabinet package delivers the commanding presence that rock, metal, and high-volume performances demand. The SA-412PKG2 combines a straight 4x12 cabinet with a slanted 4x12 cabinet, creating the classic full-stack configuration that projects sound effectively across large stages and venues.

Each cabinet handles 400 watts RMS (800 watts peak) through four 12-inch speakers with 30-ounce magnets and 2-inch Kapton voice coils. The 8-ohm impedance per cabinet means you can run both together for a 4-ohm load, maximizing power transfer from most tube and solid-state heads. The 45Hz-5000Hz frequency response captures the full range of guitar fundamentals and harmonics.

Both cabinets feature 5/8-inch plywood construction with black carpet covering and metal corner protection for durability on the road. The slanted top cabinet angles the upper speakers toward the audience and stage, while the straight bottom cabinet provides the foundation. Full metal grilles protect the speakers while allowing maximum sound projection.

This setup works perfectly for venues seating 500-2000 people, outdoor festivals, and any situation where stage volume and audience projection matter. Each cabinet offers dual 1/4-inch and dual Speakon inputs for flexible connection options.

Connect your guitar head to either cabinet, then link to the second using standard speaker cables. Both cabinets ship ready to use with recessed handles for transport. Backed by Seismic Audio's one-year warranty with fast shipping direct from the manufacturer.

Frequently Asked Questions

What's the difference between the straight and slanted cabinets in this package?

The straight cabinet (bottom) projects sound forward parallel to the floor, providing the foundation and low-end punch. The slanted cabinet (top) angles the speakers upward toward the audience and monitors, improving stage coverage and audience projection. This classic full-stack configuration maximizes both stage volume and crowd coverage.

Can I run both cabinets together with my guitar head?

Yes, each cabinet is wired at 8 ohms, so running both together presents a 4-ohm load to your amplifier. Most guitar heads work well at 4 ohms and will deliver maximum power. Connect your head to either cabinet, then use a speaker cable to link to the second cabinet using the parallel inputs.

What size venues work best with this full-stack setup?

This 800-watt peak full-stack handles venues from 500-2000 capacity including clubs, theaters, outdoor festivals, and large churches. The dual-cabinet height projects sound over crowds effectively. For smaller venues under 300 people, a single cabinet often provides sufficient volume without overwhelming the space.

What speaker cables do I need to connect these cabinets?

You'll need one speaker cable from your guitar head to the first cabinet, then another speaker cable to link between cabinets. Both 1/4-inch and Speakon connections work - Speakon provides more secure connection for touring. Use 12-gauge or thicker speaker cable, never instrument cables which can damage your amplifier.

How does this compare to buying individual 4x12 cabinets separately?

This package saves money versus buying two separate cabinets while ensuring you get one straight and one slanted cabinet for proper full-stack configuration. The slanted top cabinet is essential for stage monitoring and audience projection, while the straight bottom provides foundation. Buying individually often results in two straight cabinets.
