Overview
The Pioneer TS-A301TW is a pair of 20 mm A-Series component tweeters rated 100 W RMS and 450 W peak at 4 ohms. Polyetherimide hard domes cover 1.8 kHz to 58 kHz at 90 dB, and an inline high-pass network simplifies the add-on. Multi-Fit adapters and a 1/2-inch mounting depth help place them in OE tweeter locations.
Product details
A-Series component tweeter add-on
When the factory highs fall flat, TS-A301TW adds a dedicated 20 mm PEI hard-dome pair. Continuous handling is 100 W RMS with 450 W peak on 4 ohms and 90 dB sensitivity for a crisp top end.

PEI dome and inline high-pass
Each polyetherimide hard dome plays from 1.8 kHz to 58 kHz. An inline high-pass network ships with the pair so you can protect the domes without building a full passive board from scratch.

Multi-Fit placement
Mounting depth is 1/2 inch (12.7 mm) with a 0.79-inch tweeter and 1.5-inch outer diameter. Multi-Fit adapters help seat the pair in many OE tweeter openings — always confirm the hole before you cut.
