KEF C35 Speakers sound muffled/clogged
hey there! I got these speakers from a friend who didnt need them anymore. I connected them to my Pioneer A209R amp, listening to CD/Vinyl. The sound of the tracks on the C35? Muffled, a bit clogged.
The speakers look almost in perfect condition. I havent opened them up yet, but from outside it looks like they've been kept clean and take care after.
any idea what might cause the issue? I tried different positions, farther away from the wall etc - Ive browsed this subreddit for similar issues. I also double checked the phases.
