Infinity 429I 150W (Peak) 4 -Inch 2-Way Speaker (Pair)

The Kappa 42.9i 4"" speakers feature light, but stiff woven glass-fiber woofer cones that won't flex or distort. The Plus One design offers a larger surface area for improved low-frequency output and efficiency, while longer voice coils produce tighter, snappier midbass. Large magnets keep the woofers running cooler by placing more steel close to the voice coils to act as a heat sink.

User Reviews about Infinity 429I 150W (Peak) 4 -Inch 2-Way Speaker (Pair)

Four inch speakers are hard to get good sound from, but these little guys do the job. Unless you have a really bass-y song, they sound just like my 6"x8" speakers in my other car. When these speakers are paired with my Boss Audio 648BI it can really get loud. Some distortion occurs when I crank the sound to the maximum level, but by that time, you can't be in the car if you want to keep your hearing. Installation was easy. They look good when installed. I was very satisfied. -- Great Quality

I hooked these up in my Boxster and paired them with a JVC HD50 head unit. This are simply crisp clear and loud with no distortion. I have absolutely no negatives on these speakers. I have Klipsch home speakers hooked upto Marantz seperates. I enjoy Clear, crisp sound over noise and these delivered. They maybe expensive but you definately get what you pay for!! You can't go wrong with these. -- Simply amazing sound
