Pioneer TS-A301TW 0.75" Component Dome Tweeters

The Pioneer TS-A301TW is a pair of 20 mm component dome tweeters designed to add dedicated high-frequency reproduction to a car audio system. They are suited to listeners who want clearer treble detail than a full-range factory speaker location may provide. An included inline high-pass network is specified for use with the tweeters to help direct appropriate frequencies to the drivers.

Each tweeter uses a polyetherimide (PEI) hard-dome diaphragm and a neodymium magnet. This combination is designed for controlled high-frequency output in a compact package. With a stated frequency response extending from 1.8 kHz to 58 kHz, the TS-A301TW is intended to reproduce upper-midrange and treble information.

The TS-A301TW is rated for 100 watts RMS and 450 watts maximum music power, with ratings specified as equivalent to 4 ohms. Its 90 dB sensitivity rating is measured at 1 watt/1 meter. The nominal impedance is 6 ohms, so amplifier and speaker-system compatibility should be considered before installation.

These tweeters are a practical add-on for systems that need more high-frequency presence from the front stage. They can complement compatible midrange or full-range speakers when installed with the supplied network. The 3,800 Hz crossover frequency helps define where the dedicated tweeter begins its intended operating range.

Pioneer includes Multi-Fit installation adapters to support different mounting approaches and applicable original-equipment tweeter locations. The package also includes mounting hardware, brackets, wire adapters, and inline networks. This makes the TS-A301TW well suited to a component-style upgrade where vehicle space and mounting depth have been checked in advance.

Key Features

• 20 mm PEI Dome: A hard-dome tweeter diaphragm handles detailed upper frequencies.
• 100W RMS Rating: Supports systems with appropriately matched amplification.
• 450W Maximum Power: Provides a stated maximum music-power handling figure.
• 1.8 kHz–58 kHz Response: Covers upper-midrange and high-frequency reproduction.
• Inline High-Pass Network: Helps route suitable frequencies to each tweeter.
• Multi-Fit Adapters: Supports flexible mounting in compatible vehicle locations.

Design & Installation

The TS-A301TW uses a 20 mm PEI hard-dome diaphragm paired with a neodymium magnet. Each tweeter has a compact 50 mm outside diameter and a stated 16 mm mounting depth. No speaker grilles are included.

Use the included inline high-pass network; Pioneer cautions against operating the tweeter independently of its specified network. Confirm the available mounting space, 38 mm cutout requirement, and vehicle-specific wiring before installation. The supplied adapters, brackets, wire adapters, foam gaskets, covers, clips, and screws support several installation arrangements.
