I’m not going to continue in my great tradition of trashing infinity products, because the only infinity products that truly deserve to be dumped in the trash are the BASSLINK subs. Other than those, Infinity makes an excellent product, which is why they are one of the biggest names in car audio today.
One of the speaker series that has really excelled for Infinity has been their Infinity KAPPA PERFECT line of speakers. If someone has knowledge of car audio, they have undoubtably heard of Infinity and this series, and have probably more good to say than bad. This line has been winning competitions for years, and at just $150-$180 per speaker, you just can’t beat the performance that you get out of them.
The sound quality on these subs isn’t perfect, as the name would suggest. They definitely need a finely tuned box, that I would recommend coating with some sort of rubberized material. The reason behind this, is to prevent rattle from the box. Many subs can overcome box rattle, but the Infinity shake so hard in the box that they produce an insane amount of box rattle if not taken care of. A little carpet can help this out some, but I still recommend a bit of rubber coating, which can be purchased in a spray can and really will give huge difference to the actual thumping of the bass.
With dynamat in place, and the box not rattling, the speakers themselves under manufacturer’s specifications have great performance and can hit hard, while at the same time produce ride quality sound that you can count on over and over again.
These are some of the most indestructable speakers on the market. If you were to watch how some of my friends treat these subs, you would think that they were trying to blow them on purpose, but it’s damn near impossible. These subs can hold up to some pretty aggressive sound handling and they can do it for hours at a time, without any noticeable issues, even over the long term. I have seen these subs last 3-4 years, without any issues at all. Very rarely will you have to swap these speakers out, and if you do, it’s probably because you drilled a hole through the cone, because I just can’t picture them blowing out on their own, especially under normal use.

This is one of the most tried and true speakers on the market. It has been tested in event after event, and it is still one of the most used series of speakers on the market for competitions and road use. Regardless of the application, I have full faith that this is going to be one awesome speaker for your vehicle. They hit hard, they last a long time, and they are relatively inexpensive. So, add a couple extra subs, and let loose, because you are going to blow the birds out of the trees when you pass by with a 4 pack of these in your trunk.
