Ground Zero Iridium GZIF 4001FX 10cm 2ウェイ 薄型マウントスピーカー 50W RMS

Installed these in my car's front doors where depth was tight, and the 10cm mounting depth fit perfectly. The coated paper cone surprisingly gives a warm, detailed midrange without being harsh. For shallow speakers, they handle 50w RMS with impressive clarity even at higher volume.

The coated paper cone handles a surprising amount of bass for such a shallow 4-inch speaker, and the 90-watt max headroom means they don't strain even when I push them. The low installation depth made them fit perfectly behind my factory grilles without any cutting.

These fit perfectly in my shallow door panels where nothing else would go, and the coated paper cones already sound clear and punchy even before break-in. For the price, getting a solid 50 watts RMS with such a low mounting depth is a steal. Really happy with how they transformed my car's audio with
