As a world leading manufacturer, CELTO meticulously engineered this premium woofer to offer top class performance, consistency and long-term reliability. Featuring an exclusive blend of Canadian pulp cone reinforced by KEVLAR fibre, this high-efficiency driver has been designed to provide deep and precise low frequency reproduction in compact vented cabinets.
The 18NGW1200 features the beautifully crafted CELTO low turbulence aluminium basket with a flawless powder-coated finish, robust push terminal connectors, and 240°C thermal class voice coil (500°C peak), guaranteeing the longevity of this product.
With extensive experience serving the African market since 2010, CELTO designed the new NGW series specifically to withstand the high physical and electrical demands of our continent, including but not limited to an anti-shift motor system assembly and a dual-layer glue rivet process to avoid broken spiders.
