Replaced the mom speakers.
Connected to an amplifier and so far all good.
In this speaker size, you can't have many demands.
They play satisfactorily without spending a lot of money

vx 42: I believe you won't find a better four-inch speaker on the market. It chirps slightly at high volumes due to its size.

vx 62: Very good speakers, they don't chirp from the bass. If placed in a door, they can deliver, but not so much in a shelf. Excellent sound quality
