SALA-215S - Passive 2x15 Line Array Subwoofer

$1,099.99 $1,975.99

The SALA-215S delivers the low-end foundation that line array systems demand. This passive dual-15" subwoofer integrates seamlessly with the SALA-210 line array speakers to create full-range sound reinforcement for venues up to 500 people.

Two custom 15" woofers with 75 oz magnets and 3" voice coils push deep, controlled bass from 32Hz to 500Hz. The 4-ohm impedance and 800W RMS power handling (1600W peak) provide the headroom needed for dynamic live sound applications without distortion.

Built from birch plywood with high-intensity aluminum suspension hardware, the SALA-215S handles the rigors of touring while maintaining sonic accuracy. At 100 dB sensitivity and 130 dB maximum SPL, it delivers punchy bass response that cuts through dense mixes. The 90° x 50° coverage pattern ensures even bass distribution across wide listening areas.

Install these subs as front-of-house reinforcement in churches, schools, and performance venues, or deploy them for side-fill applications in larger spaces. The stackable design and integrated suspension points work equally well in fixed installations and portable setups.

Dual Speakon inputs simplify connection to your amplifier or powered mixer. You'll need standard speaker cables to connect from your amp to the subwoofer inputs.

Each SALA-215S ships with Seismic Audio's one-year warranty and fast shipping. Professional-grade construction meets working musician budgets.

Frequently Asked Questions

What size venues work best with the SALA-215S subwoofer?

The SALA-215S handles venues up to 500 people when paired with appropriate line array tops like the SALA-210. For smaller clubs and churches (100-200 people), one sub provides solid low-end reinforcement. Larger venues or outdoor events may benefit from multiple SALA-215S units for even bass coverage and increased headroom.

What cables do I need to connect the SALA-215S to my amplifier?

You'll need Speakon-to-Speakon speaker cables to connect your power amplifier to the SALA-215S inputs. The dual Speakon connectors allow for parallel connection or daisy-chaining multiple subwoofers. Use 12 AWG or thicker cables for runs over 25 feet to maintain proper power transfer and avoid signal loss.

Can I use the SALA-215S without line array speakers on top?

Yes, the SALA-215S works as a standalone subwoofer for bass reinforcement with any PA system. While designed to complement SALA-210 line arrays, it pairs well with conventional full-range speakers, floor monitors, or existing sound systems that need additional low-end support. The 32Hz-500Hz frequency response integrates cleanly with most main speakers.

How much power do I need to drive the SALA-215S properly?

A power amplifier rated between 600-800 watts RMS at 4 ohms will drive the SALA-215S to its full potential. Underpowering with a 400-500 watt amp still provides good performance for smaller venues. Avoid amplifiers exceeding 1000 watts RMS to prevent driver damage, and always use a high-pass filter set around 30Hz to protect the woofers from subsonic frequencies.

Does the SALA-215S include rigging hardware for line array mounting?

The SALA-215S includes high-intensity aluminum suspension hardware for professional rigging applications. However, you'll need compatible line array frames or rigging points depending on your specific installation. The cabinet also stacks securely on the floor for ground-based setups where overhead mounting isn't required or practical.
