Add a Rock-Solid Foundation to Your Music
There are times when your sound system needs additional low-frequency output and “punch.” For those situations, Alto Professional proudly offers the Alto TS312S Active Subwoofer. This subwoofer extends the bass response of virtually any full-range speaker, relieving that speaker of the difficult task of having to reproduce the low bass frequencies. The result? A system with stunning wide-range response characterised by dramatic, impactful low frequencies and effortless, undistorted mids and highs. The listening audience will hear everything with perfect clarity, from the lowest bass synth tones to thehighest percussion bells and everything in between.
TS312S features a rugged, long-excursion woofer mounted in a solidly-braced ported enclosure, computer-optimised for powerful low-frequency performance. The enclosure itself is made from a dense wood composite. This strong, resonant-free material has virtually perfect acoustic characteristics, which ensures that the subwoofers’ output is always clear and impactful. Conventional enclosures with flex-prone thin metal or plastic walls actually rob the speaker of acoustic impact by dissipating the driver’s energy as cabinet vibration. A sturdy, braced wood composite enclosure doesn’t waste the driver’s motion as cabinet resonance.
The Perfect Match
Strong, clear output is only half the battle, however in order for a subwoofer to be part of an ideal speaker system, it has to blend seamlessly with the companion speaker. This is where the Alto Professional’s TS312S truly excels. All TS300-series subwoofers have a choice of six selectable DSP output modes, so the subwoofer’s frequency response and crossover frequency are perfectly-matched to the speaker it’s being used with. Four of these six output options match the subwoofer perfectly with Alto TS2 and TS3 full-range speakers, while the other two output options (Hi-Pass or Bypass mode) ensure a perfect match even with non-Alto full-range speakers.
Precision-Engineered for Performance
Our computer design techniques feature advancements such as Finite Element Analysis (FEA), which enables us to optimise 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 utilisation of the input signal and our adhesives exhibit unrivalled consistency and durability under high temperature conditions for unsurpassed system reliability. TS312S features an on-board 2000-watt 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.
