Product Information

Fuller Sound

When Infinity’s engineers designed the REF5020CX 2-way component speaker system, they knew that they had to do something unique with their speaker kit to separate it from the pack. They knew that even high-quality 5-1/4” speakers had limitations on how much bass response they produced, so they decided to increase the size of the woofer cone, but still keep it the same size so it fit into a traditional 5-1/4” woofer chassis. This increased cone area hits lower bass frequencies and has a lot more impact in comparison to other speakers. You’ll get the most bang for your buck with these Infinity speakers.

A Good Fit

The Infinity Reference REF5020CX component speakers are a good fit for a few reasons: they are budget-friendly, work with virtually any installed car audio system, and they use a 3-ohm impedance so you can extract maximum power from their power source – whether it be factory-installed or aftermarket. Oh, and they sound really good, too.

You’ve Got Options

The folks at Infinity knew that while many people have vehicles that have separate factory-installed tweeters and woofers, not every person who looks at their speakers will have a setup like this. With that in mind, Infinity supplies additional tweeter mounts with their component speaker kits so that you can neatly add tweeters to almost any vehicle without the need for drilling out large holes or making custom mounts to integrate the new tweeters into your ride.
