TS318S features a rugged, long-excursion woofer mounted in a solidly-braced ported enclosure, computer-optimized for powerful low-frequency performance. The enclosure itself is made from a dense wood composite. This strong, resonantfree 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.

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 TS318S 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.

There are times when your sound system needs additional low-frequency output and “punch.” For those situations, Alto Professional proudly offers the TS318 powered subwoofer. This subwoofer extends the bass response of virtually any fullrange 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 characterized 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 the highest percussion bells and everything in between.
