Warzone WZ40PTi 4" 2-Way Coaxial Speaker Pair

The Warzone WZ40PTi is a pair of 4-inch, 2-way coaxial car speakers designed for compact speaker locations and general audio-system upgrades. Each pair combines a woofer and tweeter in a single speaker assembly, helping add full-range sound where installation space is limited. Its 4-ohm nominal impedance is suited to many common car-audio speaker applications.

This speaker pair is intended for listeners who need a compact replacement or upgrade option without moving to separate component speakers. The coaxial layout places the high-frequency driver over the woofer, allowing mids and highs to come from one mounting location. A 90 dB sensitivity rating supports efficient output with appropriately matched power.

Warzone rates the WZ40PTi pair at 80 watts RMS system power and 350 watts maximum system power. Its stated 100 Hz to 20 kHz frequency-response range focuses the design on midrange and high-frequency reproduction rather than deep sub-bass. For low-frequency extension, it can be paired with larger speakers or a dedicated subwoofer in a broader system.

The woofer uses a glass-fiber cone and a 10-ounce ferrite magnet, while the integrated 44 mm PEI dome tweeter uses an Ndfeb magnet. A specified 5 kHz crossover point divides the signal between the woofer and tweeter. These materials and the 2-way configuration provide a compact approach to reproducing vocal, instrument, and treble detail.

With a 3.74-inch cutout requirement and 1.66-inch mounting depth, the WZ40PTi is made for installations with limited rear clearance. The listed 2.18-inch overall height should also be checked against factory grilles, panels, and trim. It is a practical choice for vehicles or custom builds that can accommodate a 4-inch-class coaxial speaker pair.

Key Features

• 4-Inch Coaxial Pair: Combines woofer and tweeter in each compact speaker.
• 2-Way Design: Separates midrange and high-frequency reproduction within one assembly.
• 80W RMS System Rating: Supports power matching for the complete speaker pair.
• Glass-Fiber Woofer Cone: Provides the specified cone material for the midrange driver.
• 44 mm PEI Dome Tweeter: Handles high frequencies through an integrated tweeter.
• Shallow Mounting Depth: Requires only 1.66 inches of installation depth.

Design & Installation

The WZ40PTi uses a glass-fiber woofer cone, a 10-ounce ferrite woofer magnet, and a PEI dome tweeter with an Ndfeb magnet. Its coaxial construction keeps both drivers in a single 4-inch-class speaker format. The integrated crossover is specified at 5 kHz.

Before ordering, compare the vehicle or enclosure opening with the 3.74-inch cutout diameter and verify at least 1.66 inches of mounting depth behind the speaker. Also allow for the listed 2.18-inch overall height when retaining an existing grille or panel. The package is listed with two speakers, mounting hardware, and a user manual or installation guide; use appropriately matched 4-ohm channels and observe the 80-watt RMS system rating.
