Phoenix Gold ZP12D4 – no compromises
The ZP12D4 is Phoenix Gold's latest Street Bass subwoofer, combining premium sound quality with formidable performance, even in SPL applications. This driver is designed to produce maximum bass without compromising on precise and natural reproduction.
Carefully engineered components – a 3" OFC voice coil (2 x 4 Ohm), braided lead wires, a non-pressed paper cone, triple polycotton spiders, and a heavy-duty surround – ensure precise cone movement, optimal damping, and truly deep bass response.
The dual-stacked ferrite magnet and precisely dimensioned gap provide maximum magnetic flux, allowing the subwoofer to be driven efficiently and accurately even at its limits.
