Infinity Reference 510cs
5-1/4" Component Speaker System
Our take on the Infinity Reference 510cs
Delivering the clear, concert-like performance you want from your speakers is not just a matter of power. It also takes an efficient, low-distortion speaker. Infinity's new Reference separates were designed to play loud and clean.
The improved Tri-Laminate hybrid woofers have the superior sonic and weather-handling properties of polypropylene, but with a reduced mass for faster response. The tweeters, Infinity-designed from start to finish, use a pure silk dome for sparkling highs free from harshness and distortion. They can be flush- or surface mounted. The tweeter flush-mount depth is 1-1/8" and the cutout diameter is 1-25/32". The crossover modules have connections for "flat" or "soft" sound, so you can tailor the output to suit your car's acoustics.
These systems will handle plenty of power, so you can hook them up with an external amp. But they're efficient enough to play with your receiver's built-in power. 1-year warranty.Details:
- frequency response 80-20k Hz
- power range 2-75 watts RMS
