Overview
Pioneer builds this round coaxial speaker with a tweeter, a super tweeter and a cellulose fiber midrange in front of the main cone. The extra drivers split the sound across frequency ranges, and the shape suits standard round factory openings.
Wide frequency coverage and a high power rating are the reasons to look at it as a drop-in factory replacement or upgrade. The extra tweeters add detail on top. The limitation is that the listing does not say whether it ships as a single speaker or a pair, or what mounting hardware is included.
Who it's for
Daily drivers and older cars with failing factory speakers can use a direct swap. Owners of vehicles with different opening shapes, and those unsure about wiring, should check fit and use a professional installer.
Pros and cons
- Four-way coaxial drivers
- Wide frequency response
- High peak power handling
- Replaces round factory speakers
- Pair or single not stated
- Mounting hardware not listed
- Small cone limits deep bass
Performance notes
The main cone covers lows, the cellulose fiber midrange handles the middle, and the tweeter and super tweeter extend the highs. Sensitivity decides how loud it plays from a given amplifier, and the continuous rating is the safe long-term power. Clear sound at volume also depends on a firm mount and good wiring.
