HI!
I am helping my friend with Infinity Kappa 6.2i series II speakers. I was wondering if there is a need to replace non polar capacitors with a newer ones? Usually electrolytic capacitors get dry during age. Woofer cap is 146uF and 100V. Midrange has 47uF, 26uF and 36uF non polar caps. Speakers were built in between 1992-1996.
For me woofer sound really boomy and do not go lower frequencies. The woofer winds have been glued by last owner and the midrange has been replaced with an new another no name driver.
If someone knows how to get best of these speakers working with crossovers caps or changing woofer for better one please let me know. 🙂

You gave a very good, short characterisation how these speakers are supposed to sound. These are no audiophile highlights in most peoples opinion. Use your amp to adjust the bass and tremble to taste, so you can integrate the uncorrect mid a little better, but even if you had the origional part things will not improve very much.
PS yes replace the old capacitors with some cheap audio electrolithics of some value, but don't expect much. You need no 100 Volt items! Any usual bipolar for audio you can order will do. Don't spend more than 20€.

Yes, it's obvious from the pictures why that is, rubber foam is total crap for lower audio frequencies, also, there's is way too little damping material inside the box, get some glass- or rockwool and stuff up the box properly, and when you have done that, add MOAARRR!!! :)
I did REW measurements and got following results. Mic is calibrated SoundID reference. Mic placement was 0,5 meters away from speaker and positioned to the midrange level.
I will insert crossover schematic that I found from internet. If you are looking my rew measurements and this crossover schematic then what crossover changes would be good to try out for better frequency range? Kappa crossover frequencies: 500hz and 4,5kz.
DMM shows for the woofer driver 3,6 ohms. Do you have some reasonable woofer driver in mind to fit here?

Even if the frequency response doesn't look too bad, this has not much to do with reality. At 0.5 meters in a room you don't measure anything usefull. Change distance of mike position and you will see something completely different.
In room you need gated near field measurments for every driver to get something to work with.
Choosing another bass driver will need calibrated SPL and TSP measuring of the actual driver.
Better keep it for now and look for other options, like damping and, maybe, a closed or longer vent.
The x-over looks like someone knew his job, but maybe had a bad taste in music...
