Alto Professional TS15S Aktiv subwoofer
The Alto Professional TS15S is a 2500-watt active subwoofer built to anchor any PA rig with chest-pounding low end. A 15-inch driver paired with a 3-inch high-temperature voice coil pushes frequencies down to 36 Hz while sustaining 132 dB SPL for full-room coverage. Class D amplification, user-selectable EQ presets, and a phase alignment switch let operators tune the sub for live bands, DJ sets, or houses of worship in seconds.
- 2500W peak Class D amplifier delivers rafter-shaking output from a single 15-inch cabinet
- User-selectable EQ modes (Off, Live, DJ) plus 0°/90°/180°/270° phase alignment for fast system tuning
- Dual XLR+1/4-inch combo inputs and dual XLR thru outputs for daisy-chaining tops
- Internally braced MDF enclosure with 36 mm pole socket and mark-resistant splatter-spray finish
2500W Powered Subwoofer for Full-Range PA Systems
The Alto Professional TS15S packs 2500 watts of peak Class D power to anchor any PA configuration. A 15-inch driver with a 3-inch high-temperature voice coil extends low-frequency response down to 36 Hz (-3 dB) and reaches 132 dB SPL at one meter, adding the necessary heft to concert halls, clubs, and houses of worship. Designed and tuned in the USA, this cabinet is Alto Professional's most powerful subwoofer yet.
Onboard DSP and Phase Alignment
What separates this sub from generic 15-inch cabinets is onboard DSP and phase alignment circuitry. User-selectable EQ tunings (Off, Live, DJ) tailor low-end accentuation to the application, while a four-position phase switch (0°/90°/180°/270°) keeps the sub time-aligned with full-range tops. Electronic clip, thermal, and transducer overdrive protection guard the driver and amplifier against the rigors of touring and permanent installs.
Driver and Amplification
The amp and driver combination determines how cleanly a sub reproduces transients at high SPL.
- Amplifier Output: 2500 W peak @ 4 Ω — headroom for outdoor stages and large venues
- LF Driver: 15" (381 mm) woofer, 3" (76 mm) voice coil — handles sustained bass-heavy material without thermal compression
- Maximum SPL: 132 dB @ 1 m — projects cleanly across mid-sized rooms and clubs
Frequency Response and EQ Tuning
Frequency response defines how deep and wide the sub reproduces before rolling off.
- Frequency Response: 36 Hz – 110 Hz (-3 dB) — covers kick drums, bass guitars, and electronic sub-bass
- Frequency Range: 31 Hz – 123 Hz (-10 dB) — usable extension for cinematic and EDM material
- EQ Presets: Off / Live / DJ — switchable voicing without external processing
Connectivity and Physical Specs
Signal flow and physical integration determine how easily a sub drops into an existing rig.
- Inputs: 2 × XLR+1/4" (6.35 mm) combo — accepts balanced line-level signal from mixers or controllers
- Outputs: 2 × XLR thru — passes full-range signal to satellite tops without external splitter
- Enclosure: Internally braced front-ported MDF, 36 mm pole socket — supports standard speaker poles for stacked configurations
- Dimensions: 541 × 523 × 627 mm, Weight: 39.51 kg — single-person load-in for mobile rigs
