The Alto TS312S features a rugged, durable 12" woofer mounted in a sturdy ported enclosure. The enclosure itself is made of dense wood-based material. This strong, resonance-free material has near-perfect acoustic properties that ensure the subwoofer's performance is always clear and effective.

All TS300 Series subwoofers feature six selectable DSP output modes, so the subwoofer's frequency response and crossover frequency are perfectly matched to the speaker it is being used with. Four of these six output options perfectly match the subwoofer with Alto TS2 and TS3 full-range speakers, while the other two output options (Hi-Pass or Bypass mode) ensure a perfect match with non-Alto full-range speakers as well.

The voice coils of the Alto TS312S feature extremely dense windings that ensure maximum utilization of the input signal, and our adhesives exhibit unmatched resistance and durability under high-temperature conditions, providing unmatched system reliability. The TS312S features an integrated 2000-watt amplifier (1000 watts continuous) with proprietary limiting circuitry that provides electronic clip, and thermal and transducer overload protection, ensuring the system always sounds clean and clear no matter how hard it is pushed.
