The SA-4x8 bass speaker cabinet delivers professional low-end performance in a compact 4x8 configuration that fits where larger cabinets can't. Built for bassists who need full-range sound without sacrificing portability, this cabinet handles everything from jazz gigs to rock venues.

Four 8-inch speakers with 20oz magnets and 1.5-inch Kapton voice coils provide the punch and clarity that makes bass lines cut through the mix. The integrated 1-inch super tweeter with 3,500Hz crossover adds the high-frequency articulation that keeps your playing defined, even in dense musical arrangements.

At 350 watts RMS and 700 watts peak power handling with 8-ohm impedance, the SA-4x8 matches perfectly with most bass heads while delivering 97dB sensitivity for efficient volume. The 60Hz-20kHz frequency response captures the full spectrum from deep fundamentals to harmonic overtones that define your tone.

This cabinet works well for club dates, rehearsal studios, and mid-sized venues up to 200 people. The compact 22" x 22" x 16" footprint makes it ideal for musicians with limited transport space or venues with tight stage areas.

Connect via dual 1/4-inch inputs on the rear terminal cup – standard speaker cables included. The 5/8-inch plywood front baffle and black carpet covering with metal corners ensure road-ready durability.

Seismic Audio backs the SA-4x8 with a one-year warranty and ships ready to perform straight from the box.

Frequently Asked Questions

What size venues can the SA-4x8 handle?

The SA-4x8 works well for clubs, rehearsal studios, and venues up to about 200 people. With 350 watts RMS and 97dB sensitivity, it provides enough volume for most indoor gigs without needing additional cabinets. For larger outdoor events or venues over 300 people, consider pairing it with a second cabinet or subwoofer.

What cables do I need to connect this cabinet?

You'll need a standard 1/4-inch speaker cable to connect from your bass head to either of the dual 1/4-inch inputs on the SA-4x8's rear terminal cup. The inputs are wired in parallel, so you can daisy-chain to additional cabinets if needed. Never use instrument cables – only proper speaker cables rated for your amplifier's output.

How does the sound compare to a traditional 4x10 cabinet?

The SA-4x8 offers tighter, more focused low-end than most 4x10 cabinets due to the smaller driver size, while the integrated tweeter provides high-frequency detail that many 4x10s lack. It's more portable at 60 pounds but won't move as much air as larger drivers. This makes it ideal for controlled environments where definition matters more than maximum volume.

Can I use this cabinet with any bass amplifier head?

Yes, the SA-4x8's 8-ohm impedance works with virtually all bass amplifier heads. Most heads will deliver their full rated power into 8 ohms, and you can add a second 8-ohm cabinet to create a 4-ohm load if your amp supports it. Check your amplifier's minimum impedance rating before connecting multiple cabinets.

Do I need a subwoofer with this 4x8 cabinet?

The SA-4x8's frequency response extends down to 60Hz, covering most bass guitar fundamentals without additional subwoofers. The four 8-inch drivers provide sufficient low-end for typical bass playing. You might want to add a subwoofer for extended-range instruments like 5-string basses or if you play music requiring sub-bass frequencies below 60Hz.
