I’m surprised your dealer didn’t mention break-in. Speakers need dynamic music or a break-in disc played through them. They are one of the components where break-in is truly necessary. The drivers, especially the woofers are stiff right out of the box and need to physically flex in order for the sound to open up. There’s also the voice coils which move the drivers and some capacitors inside.
I agree with the 200 hour timeframe. If possible, leave them playing overnight. You can cover them with blankets or reverse the polarity on one speaker (swap + and - ) and face them toward each other. The sound will be cancelled out and there will only be a low level tinny sound.
Good advice...
