And the cutout dimensions will also be lesser than the bigger ones.

Enclosure

The frequency also makes sure to produce a crystal clear audio by removing the unnecessary noises.

Price

This feature is way more important than the others. Because every person has a specific budget in which he has to buy something. So if that gets out of hand, you cannot manage other things too.
