Mid-ranges of 2" and 3" are available to convert two-way component systems to three-way. The little 3 "Mid-range speakers, with low-frequency response to 300Hz and high sensitivity, are also an excellent plug-and-play alternative.

Great speakers

It's been only 2 days since the install, but having tweeters mounted at/near ear level is great and better than the OE stock. I don't know/think these Kappas are as good as my Morel 602 Ultra MKII (amplified), but the SQ is really good just with the head unit. Definitely would recommend on a budget or wanting to upgrade beyond OE.

Loyal to a fault

I've installed Infinity KAPPA753T in my last four vehicles

Very disappointing sound quality.

I own a pair of infinity component speakers purchased 8 years ago. They sound amazing. Decided to upgrade to infinity's new line of component speakers. Huge disappointment! They sounds lousy compared to the old line. A set of $70 Jensen speakers would sound better than these things. Infinity speakers went down the crapper for sure. I will looks to other brands in the future.
