ZPX654 Pro Midrange Audio Speaker
The ZPX654 is the latest pro-grade midrange driver from Phoenix Gold. Building on the ZP65 6.5 inch midrange, the ZPX654 steps up in power, efficiency, and SPL.
Key Features
- 1.5 inch OFC high-temperature voice coil for reliable performance under demanding conditions.
- Triple roll cloth surround for precise, efficient cone movement and clear output.
- 20oz ferrite motor delivering substantial driving force.
- Woven tinsel leads for durable, long-lasting connectivity.
- Lightweight paper cone engineered for high efficiency and output.
The ZPX654 is designed around efficiency and volume. The combination of a lightweight paper cone, triple roll cloth surround, and a precisely specified spider works in harmony with the 20oz ferrite motor. This avoids energy wasted on heavy dust caps or rubber surrounds, converting power directly into sound.
The result is a speaker that is loud, precise, and wide in bandwidth — built to push the limits of what a pro audio midrange driver can deliver in a car install.

About the Phoenix Gold ZPX654
From our tech experts at CEN
The Phoenix Gold ZPX654 is a 6.5 inch (165mm) pro audio midrange driver, not a coaxial speaker, so it has no tweeter. It handles 200w RMS and 400w maximum at 4 ohm, with 91.4 dB sensitivity and a 100 Hz to 10 kHz range. A 1.5 inch OFC voice coil and 20oz ferrite motor are built for high-output installs.
Who it suits
Loud builds and SPL systems where efficiency matters more than a simple door swap. It steps up from the ZP65 in power and efficiency. The 8 inch ZPX84 is the other size in the range.
Our tech experts advise
Pro midranges need a high-pass filter well clear of the bass and a pro tweeter to cover the top end. Check the 141mm mounting diameter and 75mm depth before ordering, as they often go into pods or custom panels rather than factory locations. Installation is priced per vehicle, so get in touch with your make, model and year.

Frequently Asked Questions
Q: Will these speakers fit my car?
A: Most car speakers are standard sizes, but mounting depth and fitting rings vary by vehicle. Check the size in the Specification tab against your vehicle, or contact CEN with your registration and we will confirm fitment and any adapters or fitting kits you need.
Q: Do I need an amplifier to run these speakers?
A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.
Q: What is the difference between coaxial and component speakers?
A: Coaxial speakers combine the tweeter and woofer in one unit for a simple like-for-like upgrade. Component sets separate the tweeter and woofer with a crossover for better imaging and detail, and suit installs where sound quality is the priority.
Q: Do these come as a pair?
A: Unless stated otherwise, car speakers are sold in pairs. Check the product title and What's Included tab, which lists exactly what is in the box.
Q: Can CEN fit these speakers for me?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
Q: How much power can the Phoenix Gold ZPX654 handle?
A: The ZPX654 is rated at 200W RMS and 400W max, with a 4 ohm impedance and 91.4dB sensitivity.
Q: What mounting depth does the ZPX654 need?
A: It needs 75mm of mounting depth and a 141mm mounting diameter. Grilles are not included.
Q: What frequency range does the ZPX654 cover?
A: The ZPX654 covers 100Hz to 10kHz, so it is designed for midrange duties rather than deep bass.
