About the Phoenix Gold ZP65BOX
From our tech experts at CEN
The Phoenix Gold ZP65BOX is a dual-ported full-range SPL speaker enclosure. Inside the MDF box are four 6.5 inch pro audio midrange drivers and two 3.8 inch pro audio tweeters, rated together at 850w RMS and 1700w maximum, with a 90 Hz to 20 kHz range. It connects through two 4 ohm terminals, left and right.
Who it suits
Builds that want high sound pressure from a ready-made box, indoors or out, rather than cutting pro drivers into panels. Add a subwoofer to cover the bass below 90 Hz. For loose drivers to build into your own panels, see the ZP65 midranges.
Our tech experts advise
It needs a 2-channel amplifier with a high-pass filter. The box measures 920 x 160 x 200mm, so secure it properly in the vehicle. Installation is priced per vehicle, so get in touch with your make, model and year.
