Alto TS15S Description
The
Alto TS15S is engineered to deliver punchy, room-filling bass that complements your top cabinets and elevates the overall sound experience. Its 15-inch woofer features a 3-inch high-temperature voice coil, housed in a rugged, front-ported MDF enclosure that minimizes unwanted resonance while maximizing impact and clarity.
Perfect for live performance venues, nightclubs, houses of worship, or portable event systems, the TS15S is Alto Professional’s most powerful sub to date. Its high-efficiency Class D amplifier delivers clean, powerful output with headroom to spare—reaching a maximum SPL of 132dB.
Onboard DSP provides three EQ tuning modes—Off, Live, and DJ—to adapt the low-frequency output to your specific needs. The Phase Alignment switch offers four positions (0°/90°/180°/270°), making it easy to blend the sub with any full-range setup for maximum clarity and impact.
Built for real-world use, the cabinet includes a 36 mm pole socket for mounting satellite speakers and is finished in a durable, mark-resistant coating that stands up to heavy use. Rear-panel combo inputs and XLR link outputs offer flexible connection options, while built-in protections ensure long-term reliability.
