Car HiFi subwoofer speakers of a special design and great sound. The SILVER subwoofers have a special position even in the range of high-quality woofers due to their high-quality aluminium diecast basket, the super stable aluminium laminated cone in a special rubber surround, and the chromium-plated components of these bass speakers. Top subwoofer speaker, 500WMAX, 4Ω, suitable for very compact bass-reflex cabinets. Ideal size of cabinet of only approx. 25 litres, but already with a very low limit frequency.
