Highlights 

speaker sizes and types – The Infinity Reference X Series 

has speakers for almost any application, so you can upgrade 

your present system’s performance by simply replacing its 

speakers. 

Plus One woofer cones – With a greater radiating area than 

conventional speakers of the same size, Plus One cones can 

play louder with smaller amplifiers, increase bass output to 

eliminate bothersome road noise and deliver increased 

performance, without making you modify your vehicle. 

True four ohms – All Reference X Series speakers feature 

three-ohm voice coils to compensate for increased impedance 

caused by thin-gauge factory-installed speaker wiring. 

Reference X speakers can handle the maximum power that 

factory stereo can offer and deliver greater output than factory 

speakers.

Edge-driven, textile-dome tweeter (all except 3002cfx) –

The Reference X Series’ tweeter provides greater power 

handling and lower distortion than conventional tweeters, 

improves integration with the midrange/woofer driver and 

upgrades audio clarity and presence.
