The SA-115 1x15 Bass Guitar Speaker Cabinet delivers the low-end punch bassists need for practice rooms, rehearsals, and small to medium gigs. This single-15 cabinet handles 300 watts RMS and peaks at 600 watts, giving you serious power handling in a manageable package.

Built around a custom 15-inch driver with a 50-ounce magnet and 2.5-inch Kapton voice coil, the SA-115 produces deep bass response down to 40Hz while maintaining clarity in the midrange up to 5kHz. The dual-ported design enhances low-frequency output and efficiency, while the 8-ohm impedance makes it compatible with most bass heads and combo amps.

At 96dB sensitivity, this cabinet moves plenty of air without requiring massive amplifier power. The 5/8-inch plywood front panel and black carpet covering with metal corners provide durability for regular transport. Dual ports positioned centrally optimize airflow and reduce port noise during high-output performance.

The SA-115 works well as a standalone cabinet for rehearsals and smaller venues up to 150 people, or pair it with a 2x10 or 4x10 cabinet for larger stages and outdoor events. Two 1/4-inch inputs on the terminal cup allow easy daisy-chaining to additional cabinets when you need more coverage.

Connect your bass head using a standard speaker cable to either 1/4-inch input. The recessed handle and 48-pound weight make load-in manageable for most players. Seismic Audio backs the SA-115 with a one-year warranty and ships nationwide.

Frequently Asked Questions

What size venues can the SA-115 handle?

The SA-115 works well for rehearsal spaces, small clubs, and venues up to 150 people as a standalone cabinet. For larger venues or outdoor events, pair it with additional cabinets or use it as part of a mixed-driver setup with 2x10 or 4x10 cabinets for extended frequency response and increased output.

What cables do I need to connect this cabinet?

You'll need a standard speaker cable with 1/4-inch plugs to connect from your bass head or combo amp's speaker output to either input on the SA-115. Never use instrument cables for speaker connections. If daisy-chaining multiple cabinets, use additional speaker cables between the cabinets' 1/4-inch inputs.

Can I use this cabinet with any bass head?

Yes, the SA-115's 8-ohm impedance works with most bass heads and combo amps. Make sure your amplifier can handle an 8-ohm load and doesn't exceed the cabinet's 300-watt RMS power handling. Check your amp's manual for minimum impedance requirements before connecting.

How does the SA-115 compare to a 4x10 cabinet?

The SA-115 emphasizes deep low-end response that 4x10 cabinets often can't match, while 4x10s typically provide more midrange punch and clarity. Many bassists use both together – the 15-inch driver handles the low frequencies while the 10-inch drivers cut through the mix with midrange definition.

Do I need a subwoofer with this bass cabinet?

No, the SA-115 is designed as a full-range bass cabinet with response down to 40Hz, covering the fundamental frequencies of a bass guitar including low B on 5-string basses. Adding a subwoofer would be redundant for most bass guitar applications, though it might benefit keyboard players using the cabinet for synthesizer bass.
