If you're running a line array system that needs serious low-end support, the SALA-215S delivers the foundation your mix has been missing. This dual-15" passive subwoofer was built specifically to pair with line array tops like the SALA-210, giving you full-range coverage for venues up to 500 people without breaking your gear budget.

The two custom 15" drivers with 3" voice coils and hefty 75-oz magnets push clean, controlled bass from 32Hz up to 500Hz. At 800 watts RMS (1600W peak) into 4 ohms, you get real headroom for those dynamic moments when the kick drum and bass guitar hit together. The 100 dB sensitivity means you're not fighting your amplifier to get volume, and 130 dB max SPL gives you enough punch to cut through a dense mix without distortion.

What sets this apart from budget subs is the birch plywood construction and aluminum suspension hardware — gear that survives the load-in/load-out cycle. The 90° x 50° coverage pattern spreads bass evenly across your audience instead of creating dead zones or hot spots that plague cheaper cabinets. Whether you're mounting it in a line array configuration or stacking it on the floor for reinforcement, the dual Speakon inputs make connections straightforward.

This isn't a powered sub, so you'll need a dedicated amplifier — think 600-800 watts RMS at 4 ohms to get the most out of it. It works as a standalone subwoofer with any PA system, not just line arrays, making it versatile for churches, schools, and performance venues where you need reliable bass extension.

Bottom line: If you need professional-grade subwoofer performance for mid-sized venues without the premium price tag, the SALA-215S delivers the low-end foundation your system needs.

Frequently Asked Questions

What amplifier power do I need for the SALA-215S?

You'll want 600-800 watts RMS at 4 ohms to properly drive this sub. A 500-watt amp will work for smaller venues, but you'll hit the limits quickly. Don't go over 1000 watts RMS — you risk blowing the drivers. Always use a high-pass filter around 30Hz to protect the woofers from subsonic content.

Can I use this subwoofer with regular PA speakers instead of line arrays?

Absolutely. While it's designed to complement SALA line arrays, the SALA-215S works great as bass reinforcement for any PA system. The 32Hz-500Hz response integrates cleanly with most full-range speakers, floor monitors, or existing mains that need more low-end support.

How many SALA-215S subs do I need for my venue?

For 100-200 people (small clubs, churches), one sub provides solid reinforcement. Medium venues (300-400 people) typically need two for even coverage and headroom. Larger spaces or outdoor events benefit from multiple units. If you're fighting to hear bass in the back of your venue, you probably need more subs, not more power.

What cables do I need to connect this to my amp?

Standard Speakon-to-Speakon speaker cables. The dual Speakon inputs let you parallel connect or daisy-chain multiple subs. Use 12 AWG or thicker cables for runs over 25 feet to avoid power loss. Don't use instrument cables or XLR — you need proper speaker cable for this power level.
