This model features a massive \u003cstrong\u003e18-inch\u003c\/strong\u003e (457 mm) speaker with a 3-inch voice coil, powered by an extremely powerful Class D amplifier, reaching \u003cstrong\u003e2500 W\u003c\/strong\u003e (Peak) power. This allows it to generate up to 137 dB of sound pressure and reproduce low frequencies from 29 Hz.\u003c\/p\u003e\n\u003cp\u003eThe TS18S offers professional sound tuning functions, allowing it to be ideally integrated into any system. Users can choose from three EQ settings (\"Off\", \"Live\", \"DJ\") and use an advanced 4-position phase alignment switch (0°\/90°\/180°\/270°), which is particularly important when matching low frequencies with main speakers in acoustically challenging rooms.\u003c\/p\u003e\n\u003cp\u003eThe cabinet is made of thick, internally reinforced MDF composite, which ensures a strong, \"tight\" sound without unnecessary cabinet resonances. The surface is covered with a special, abrasion-resistant \"mark-resistant splatter-spray\" finish. The back of the speaker has provisions for mounting casters (M6 threads, casters sold separately) for easier transport.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower:\u003c\/strong\u003e 2500 W Peak powerful Class D amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeaker:\u003c\/strong\u003e 18-inch (457 mm) woofer with a 3-inch voice coil.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEQ settings:\u003c\/strong\u003e 3 modes (\"Off\" - flat, \"Live\" - concert, \"DJ\" - enhanced).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase control:\u003c\/strong\u003e 4-position switch (0°\/90°\/180°\/270°) for precise phase alignment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Internally reinforced MDF cabinet with a 36 mm pole mount socket.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection:\u003c\/strong\u003e Electronic protection against overload (clip), overheating, and speaker over-excursion.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eManufacturer: Alto Professional\u003c\/li\u003e\n\u003cli\u003eModel: TS18S\u003c\/li\u003e\n\u003cli\u003eType: Active Subwoofer\u003c\/li\u003e\n\u003cli\u003eOutput Power: 2500 W Peak @ 4Ω\u003c\/li\u003e\n\u003cli\u003eLF Driver: 18.0” (457 mm) with 3.0” (76.2 mm) high-temperature voice coil\u003c\/li\u003e\n\u003cli\u003eFrequency Response: 29 Hz – 100 Hz (-3 dB)\u003c\/li\u003e\n\u003cli\u003eFrequency Range: 27 Hz – 111 Hz (-10 dB)\u003c\/li\u003e\n\u003cli\u003eMax SPL: 137 dB (@1m)\u003c\/li\u003e\n\u003cli\u003eConnectors:\n\u003cul\u003e\n\u003cli\u003e2 x XLR \/ 1\/4” (6.35 mm) Combo Inputs (female)\u003c\/li\u003e\n\u003cli\u003e2 x XLR Thru Outputs (male) (for signal pass-through)\u003c\/li\u003e\n\u003cli\u003e1 x IEC power socket\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eDimensions: 678.2 x 530.9 x 627.4 mm\u003c\/li\u003e\n\u003cli\u003eWeight: 42.2 kg\u003c\/li\u003e\n\u003cli\u003eCasters: Ready for mounting (M6 x 1.0 mm threads, casters not included)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat's in the box?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x ALTO TS18S Subwoofer\u003c\/li\u003e\n\u003cli\u003e1 x IEC Power Cable\u003c\/li\u003e\n\u003cli\u003e1 x Registration Card\u003c\/li\u003e\n\u003cli\u003e1 x User Guide\u003c\/li\u003e\n\u003cli\u003e1 x Safety and Warranty Instruction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIntended for?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLarge nightclubs and festivals where maximum low-frequency pressure is required.\u003c\/li\u003e\n\u003cli\u003eRental companies serving large events.\u003c\/li\u003e\n\u003cli\u003eConcert halls looking to ensure full, deep sound without compromise.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Alto Professional","offers":[{"title":"Default Title","offer_id":55791636676994,"sku":"4821318","price":676.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0931\/9736\/9730\/files\/imgi_16_TS18_34_D1-web1.jpg?v=1768897967","url":"https:\/\/stageiq.lt\/en\/products\/alto-professional-ts18s","provider":"STAGE IQ","version":"1.0","type":"link"}
