Overview
A 6.5-inch two-way component speaker system sold as a pair, pairing a ferrite-magnet woofer with a water-repellent paper cone and a neodymium-magnet tweeter with a PEI dome.
As a component set, the woofer and tweeter mount separately with a crossover between them rather than sharing one cone like a coaxial speaker, which is what allows the tweeter to sit higher on the dash or A-pillar for imaging while the woofer stays in the door. Hertz lists no separate power handling or sensitivity figures in this data, so those are worth checking against a factory spec sheet before pairing with an amplifier.
- 6.5-inch two-way component pair
- Ferrite magnet woofer
- Neodymium magnet tweeter
- PEI tweeter dome, water-repellent paper woofer cone
Who it's for
Car audio buyers upgrading from stock door speakers who want separate tweeter placement rather than a drop-in coaxial. Less useful for anyone wanting a simple one-piece replacement speaker.
Strengths and trade-offs
Drawn from this product's published specifications.
- Component design allows separate tweeter placement
- Water-repellent woofer cone suits door mounting
- Neodymium tweeter magnet keeps the housing compact
- No power handling or sensitivity figures given in this listing
- Requires running separate tweeter wiring, unlike a coaxial speaker
Performance notes
The PEI tweeter dome sits on a neodymium magnet, which keeps the tweeter housing small enough for flush mounting in tight dash or pillar locations, while the woofer's ferrite magnet and water-repellent paper cone are built for the humidity swings inside a car door.

Common buyer questions answered straight from the product spec data - no fluff, no "it depends".

It is a two-way component system, with the woofer and tweeter as separate pieces connected through a crossover rather than one combined speaker.
Does it come as a pair?
Yes, this listing covers one pair, for both the driver and passenger side.
What is the tweeter made from?
The tweeter uses a PEI dome driven by a neodymium magnet, which keeps its housing compact.
