Infinity Kappa Perfect 6.1

These speakers have good bass but the tweeters are somewhat harsh. They only bothered me a few times but got better after break in. I was feeding them 300w each and they took it like a champ. They look like some well built speakers. I will probably end up buying them again when i do another build. my only real complaint is that they do not have a BIamp option, but most components do not have that option.

My first time installing component set and these were easy to install. Sound great and have some good bass too. They get loud and still sound great. I have them ampd at 100w rms.

I didn't really like this set , they weren't worth the money to me, an equally valued set from JBL did much better, the tweeters of this set were very harsh and bright, but to harsh, couldn't do some music very well.

I've installed this set in my Nissan 370Z after being very disappointed with the factory sound set up.

For those interested these speakers are run off an Eclipse AVN62D headunit and being powered by a Boston Acoustics GT2125 amp putting out 125 wts RMS each at 4 ohms.

These speakers scream! Very clear sound up to the point where my ears hurt. I have the crossovers set at the +5 setting for the highest highs as I like my treble to be very crisp (I have two huge subs in the hatch to cover the rest) and the sound is very clean. The mids kick out a very nice amount of bass - somewhat comparable to a high output 8" sub - and fill out the range very well.

I think for an average consumer this set up with a powerfull 8" or a good 10-12" sub would create a very admirable system worthy of compliments from anyone.

One thing to note - the tweeters are dome shaped. Was hard for me to tell in the pictures. This required me to make a custom bracket to mount them lower in my dash so the stock grill would cover them. But, it also allowed me to angle them directly to the center point between the driver and passenger for optimal sound.

For me, this was worth the investment and money well spent.

I really don't like these, the mids are very good, with very good clean crisp hits, but not to powerful. i got them because of infinity being known for their bright highs, i wanted them to lead...but aside from being very bright, they have no power behind them, the tweeters were extremely twangy sounding in comparison to the JBL's in my rear seat set. they really aren't sharp at all, they can produce acoustic guitars and vocals decently, but they are worth 100-120$ tops, which is pathetic since this is infinitys top end set.
