If you're after quality sound, you need a quality install.
A $1000 speaker can sound like a $100 speaker purely due to poor install.
As you can see in this install, we installed sound deadening material around the woofer and also a sound pad on the door skin behind the speaker magnet.
The material around the woofer is designed to have a tight fit between the speaker and door trim. This focuses the air pressure created from the speaker to exit the door trim, rather than spread around it.
The sound pad behind the woofer magnet is designed to eliminate unwanted vibrations through the door skin. In return, it allows the speaker to respond much more efficiently which results in more consistent quality through the volume range.
