Re: I have Focal KR 165 and ARC amp KS 300.2 and need to adjust sound. Please help
Midbass shouldn't sound harsh. It's probably coming from higher frequencies. Instruments will cover a wide range of frequencies, and what may start at 80 Hz, for example, could have harmonics playing much higher that can sound offensive.
The easy answer to your question about active or passive is if you don't know what active means then you're not running active. What we call "active" means powering the tweeters and woofers without using the crossovers that come with the kit. The tweeters get their own amplifier channels.
To adjust the tweeter level switch you need to get to the crossovers and remove the covers. It should be fairly obvious once you do that since the circuit board or cover will be labeled.
