Year / Model Reviewed: 2004 Infinity Kappa Perfect 10.1
Strengths: Super SQ quality, Hard hitting. These subs will go wayyy low with no problem, other subs i've heard can't take what these can and still sound clear.
Weaknesses: No weaknesses just don't forget to break them in for a good 15-20 hours before throwing the watts at them.
Summary: I strolled in here after hearing a friends kappa perfect to read some of the reviews. He had one 10" and it sounded awesome driven by a JBL 600.1 I've always liked Infinity products and was curious what was being said in reviews. Bought 2 of the perfect 10.1's and built my own custom box for these subs. I can't believe these subs are only 84 bucks each! I've heard subs that cost twice as much not sound as good as these do! I'm driving them with a JBL 1200.1 @ 2ohms. These subs hit HARD! They are super clear and defined! SUPER SQ! Plenty SPL! I still can't believe these are only 84 bucks brand new!! I HIGHLY RECOMMEND PEOPLE! You will not find a better sub on the market for this price. I'm still shocked! Take a look at them, they are really built, no cheap stuff here.
Weaknesses: Too delicate, will break, they're expensive and overrated.
Summary: I made a 3/4 mdf box 1.2 cuft for 2 kappa perfects. Replacing a Fosgate Power 15 inch hx2. These Infinity's are worthless. I hooked them up @ 2ohms to alpine 1507 and they couldn't hang and don't get loud at all. The next morning one is blown.

Strengths: Stong Sub - Loud and Clean - Great with a quality amp like my Autotek SX-2150
Weaknesses: One Kappa Perfect 10.1 is not a SPL setup - Though it rattles my rear view mirror and I can definitly feel the thump. Of course it is way in the trunk of my Mercury Sable - in a smaller car you would feel alot more
Summary: Awsome Sub - a little louder than my JL Audio 10w3 D4. Good looks and quality sound. Make sure you size your box right - not to big on a sealed box. This sub can take all of the power of my Autotek amp running at 300watt RMS at 4 ohms Bridged - Keep in mind that the Autotek is way under rated and I got scared running my JL 10w3 D4 on it, It would have blow for sure - to much over a long period; that is why I got this Kappa Perfect 10.1
