The SA-215 2x15 bass guitar speaker cabinet delivers the deep, punchy low end that bass players and sound engineers need for professional performances. Built with dual 15-inch woofers, this cabinet handles 600 watts RMS and peaks at 1200 watts, making it suitable for medium to large venues and outdoor events.

Each 15-inch driver features a substantial 50 oz magnet and 2.5-inch Kapton voice coil, engineered to reproduce the full bass spectrum from 30Hz to 5KHz with 99 dB sensitivity. The 4-ohm impedance configuration ensures efficient power transfer from your bass head or power amplifier, while the robust construction maintains clarity even at high output levels.

This cabinet works well as a standalone bass rig for club gigs and rehearsals, or pairs with additional cabinets for larger venues up to 500 people. The dual 1/4-inch input jacks allow daisy chaining multiple cabinets, and the terminal cup design keeps connections secure during transport. Built from plywood with a 5/8-inch front baffle, the cabinet features black carpet covering, metal corners, and a protective metal grille.

Setup is straightforward with any bass head or power amplifier using standard 1/4-inch speaker cables. The recessed handles and 66-pound weight make it manageable for load-in, while the 36" x 19" x 15" footprint fits most stage configurations.

Seismic Audio backs the SA-215 with a one-year warranty and ships ready to perform straight from the box.

Frequently Asked Questions

What size venues can the SA-215 bass cabinet handle?

The SA-215 works well for clubs, theaters, and outdoor events accommodating up to 500 people. Its 600-watt RMS power handling and high sensitivity make it suitable for most live sound applications where deep bass presence is needed. For larger venues or festivals, consider pairing multiple cabinets.

Can I connect multiple SA-215 cabinets together?

Yes, the SA-215 features dual 1/4-inch input jacks specifically designed for daisy chaining additional cabinets. When connecting multiple 4-ohm cabinets, ensure your amplifier can handle the resulting impedance load. Two SA-215 cabinets connected in parallel present a 2-ohm load to your amplifier.

What cables do I need to connect this cabinet to my bass head?

You'll need a standard 1/4-inch speaker cable to connect the SA-215 to your bass amplifier head. Never use instrument cables for speaker connections as they can damage your amplifier. Speaker cables are designed to handle the higher current and power levels between amplifiers and cabinets.

How does the SA-215 compare to single 15-inch bass cabinets?

The dual 15-inch configuration provides greater surface area for moving air, resulting in higher output and deeper bass response than single-driver cabinets. This translates to more punch and presence on stage, especially in the critical low-mid frequencies where bass guitars need to cut through the mix with drums and guitars.

Do I need a subwoofer when using the SA-215 for live bass?

Most bass guitar applications won't require an additional subwoofer with the SA-215, as it reproduces frequencies down to 30Hz effectively. However, if you're using synthesizers, extended-range bass guitars, or need extremely deep sub-bass for electronic music, adding a dedicated subwoofer can enhance the lowest octave.
