New Infinity REF507F Reference Series 5.25 135W Peak Power Handling 3 Ohms 2-way Coaxial Car Speakers (Pair)

New Reference speakers are designed to deliver Infinity’s signature sound in more vehicles. They feature edge-driven textile tweeters for smooth. clear highs and the larger models offer an adjustable tweeter output level control for high-frequency optimization based on installation location or the listener’s preference. Oversized Plus One? woofers offer more surface area for higher bass output and enhanced midrange performance. Plus our newly engineered baskets are optimized to fit most factory speaker locations.

Features
Edge-driven. textile tweeters
The audiophile-grade tweeters used in Infinity’s new Reference speakers deliver smooth. non-fatiguing sound even at high output levels.

Adjustable tweeter output level
The larger Reference multielement and component systems offer a tweeter output level control to optimize system linearity to suit installation location or the listener’s preference.

Plus One? woofer cone architecture
Harman’s patented (US patent #7.548.631) Plus One? cones provide more overall speaker-cone area than other cones in its class – the result is higher sensitivity. increased low-frequency output and accurate music reproduction.

Optimized frame size
Reference speakers are available in a range of standard sizes. and feature a compact design that allows them to fit just about any vehicle on the road today.
