That's why, all the Alto TS300 series subwoofers give you a choice of six selectable DSP output modes. 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. Indicators: Signal/clip limiter LED, polarity-reverse LED, extended low-frequency LED, power switch LED

Our computer design techniques feature advancements such as Finite Element Analysis (FEA), which enables us to optimize the speaker’s magnetic structure and maintain a tight voice coil gap for maximum sensitivity. Our voice coils themselves have extremely tight windings that ensure maximum utilization of the input signal and our adhesives exhibit unrivalled consistency and durability under high temperature conditions for unsurpassed system reliability.External Controls: Volume control, signal/clip limiter with LED, DSP output mode switch with LED, polarity-reverse switch with LED, extended low-frequency switch with LED, power switch with LED

Extending the bass response of virtually any full-range speaker, the Alto TS3S12S powered subwoofer gives you deep low-frequency and powerful punch. With the Alto Professional TS312S as part of your system, your full-range speakers don't have to push out the bass frequencies.

Standard sub enclosures are made from thin metal or plastic which weakens your sound as the enclosure absorbs energy from the driver as cabinet vibration. Four of these six DSP output options are designed to perfectly match your sub with Alto TS2 and Alto TS3 full-range speakers. The remaining two output modes; Hi-Pass and Bypass mode make it so you can get the perfect match with full-range speakers from other brands. Precision-Engineered for Powerful Performance Our computer design techniques feature advancements such as Finite Element Analysis (FEA), which enables us to optimize the speaker’s magnetic structure and maintain a tight voice coil gap for maximum sensitivity. Our voice coils themselves have extremely tight windings that ensure maximum utilization of the input signal and our adhesives exhibit unrivaled consistency and durability under high temperature conditions for unsurpassed system reliability. TS312S features an on-board 2000watt amplifier (1000 watts continuous) with proprietary limiting circuitry that provides electronic clip, thermal and transducer overload protection, ensuring that the system always sounds clean and clear, no matter how hard it’s pushed.
