Infinity REF507F (INFSPKRF507FUS)

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 newly engineered baskets are optimized to fit most factory speaker locations. Available in a range of standard sizes, they’re the perfect upgrade from factory speakers.
