Specifications
| Price (US) | Not published No verbatim US-dollar price could be sourced from a fetchable page. The official manufacturer page lists no price. A web search shows Sweetwater at $399.00, but that page (and B&H) returned HTTP 403 and could not be fetched to source verbatim. The two pages I could fetch showed geolocated non-US pricing (Alto Music: EUR 355,95) or no US price at all (Amazon displayed "—" with shipping blocked). Left null rather than guessed. |

Source: altoprofessional.com (verified 2026-07-13) · corroborated by altomusic.com. The official Alto Professional TS412 page (TrueSonic 4 Series) confirms the exact model and its full spec sheet: 2500 W peak output, 12" LF driver, Maximum SPL 132 dB (peak), Frequency Range 44 Hz–20 kHz (-10 dB), Horn Coverage 90° horizontal x 60° vertical, class D amplifiers, integrated 3-channel mixer, Bluetooth streaming, on-board DSP (4 Speaker Use modes), and 33 lbs / 15 kg net weight. The Alto Music retailer page corroborates the identical spec sheet verbatim and confirms model identity (MPN TS412XUS, UPC 816311012058); Amazon further confirms model TS412 / UPC 816311012058 and the 132 dB / 2500 W / 33 lbs figures. Neither fetchable page provided a US-dollar price — the manufacturer lists none and the retailer showed geolocated EUR pricing — so priceUsd is left null. enclosureMaterial is null because the stated "Injected Molded Enclosure / Perforated Metal Grille" (and Amazon's "Metal, Plastic") does not match any allowed enum value.
