For those occasions when you need more low-frequency output and punch from your PA, the Alto TS318 powered subwoofer extends the bass response of almost any fullrange speaker, relieving that speaker of the job of reproducing low bass frequencies. This results in a system with an outstandingly wide-range response, with dramatic and powerful low frequencies, and clean, undistorted mids and highs - so your audience can hear everything with pristine clarity, from the lowest bass synth sounds, to the most brilliant percussion and bells, and everything between.

Premium Components

Featuring a robust long-excursion woofer mounted in a braced, computer-optimized, ported enclosure for powerful low-end replication, the enclosure of the TS318S is constructed from a dense wood composite. This rugged material boasts virtually perfect acoustic characteristics, and is free of resonance - ensuring that the subwoofer's output remains clean and impactful.

The Perfect Match

In order for a subwoofer to work with a speaker system, it must seamlessly combine with the companion speaker. This is where the Alto TS318 excels. With six selectable DSP output modes, the frequency response and crossover frequency of the TS318S are perfectly matched to the speaker it's being used with.

Precision-Engineered for Performance

Alto's computer design techniques feature advancements like Finite Element Analysis (FEA), enabling an optimized magnetic structure of the speaker, and a tight voice coil gap for maximum sensitivity. With extremely tight windings, Alto's voice coils ensure maximum use of the input signal, and their adhesives exhibit unparalleled consistency and durability in high-temperature conditions for unmatched system reliability. Driven by an integrated 2000W amplifier, the TS318S features exclusive limiting circuitry that provides protection from electronic clipping, and thermal and transducer overload, to ensure that the system always remains clear and clean, regardless of how hard you're pushing it!
