Atlas Sound SM12SUB70-W 12" Surface Mount Subwoofer with 60-Watt 70V/100V Transformer (White)

Product Overview

The Atlas Sound SM12SUB70-W is a 70V surface mount subwoofer built to add low-frequency reinforcement to 70.7V/100V distributed audio systems and 8-ohm commercial sound installations. Its built-in 60-watt high-efficiency transformer lets integrators parallel the subwoofer directly onto an existing 70-volt speaker line without adding a dedicated amplifier or external crossover. The compact multi-angle wood enclosure, finished in white, includes multiple 1/4"-20 inserts for suspended or wall-mounted placement in retail, hospitality, and commercial meeting spaces. For background and foreground music systems that need more audio impact below 125Hz, this is a straightforward, single-box solution.

Product Description

Distributed audio systems excel at even coverage but often lack low-end weight. The SM12SUB70-W addresses that gap with a long-excursion 12" woofer housed in a multi-angle wood enclosure, delivering 45Hz–125Hz response with 89dB sensitivity and 250W RMS power handling. A built-in 18dB-per-octave three-pole passive crossover network handles low-pass filtering internally, so commercial subwoofer installation requires no outboard DSP or separate crossover hardware. The internal 60-watt 70.7V/100V transformer offers taps at 7.5, 15, 30, and 60 watts, and can be bypassed entirely for 8-ohm operation in low-impedance system designs. Wiring is handled through a barrier strip input for 70.7V/100V/8-ohm connections or a parallel 4-pole speakON input for 8-ohm use, and the input panel accepts a standard 4" square box cover when flex conduit termination is required by code. Multiple 1/4"-20 inserts provide fly points for suspension, and the cabinet is OmniMount compatible with an optional wall-mount bracket available. A durable rough-coat white finish and heavy-duty grille assembly hold up in public commercial environments. For AV integrators specifying 70-volt commercial audio system upgrades, the SM12SUB70-W pairs naturally with AtlasIED surface mount and ceiling speakers; browse compatible models in our AtlasIED collection at Creation Networks.

Frequently Asked Questions

Can the SM12SUB70-W run on both 70-volt and 8-ohm systems?

Yes. The internal 60W transformer supports 70.7V and 100V distributed lines with selectable taps, and it can be bypassed for direct 8-ohm low-impedance operation.

Do I need a separate amplifier or crossover for this subwoofer?

No. The built-in three-pole passive crossover filters the signal internally, so the subwoofer connects in parallel with your existing 70-volt amplifier and speaker line.

How is the SM12SUB70-W mounted during installation?

The cabinet includes multiple 1/4"-20 inserts for suspension fly points, is OmniMount compatible, and supports an optional bracket for wall mounting.

Does it support conduit wiring for commercial code compliance?

Yes. The input panel accepts a standard 4" square box cover for installations where flex conduit termination is required.

What warranty does AtlasIED provide?

The SM12SUB70-W carries a 60-month warranty from the date of purchase. Creation Networks supports your order with pre- and post-sale assistance for commercial AV deployments.

Is this subwoofer a good match for AtlasIED ceiling speaker systems?

Yes. It is designed to parallel with any 70.7V commercial audio system, making it a direct low-frequency companion to AtlasIED 70V ceiling and surface mount speakers.
