Awesome manufacturer who is pushing the limits of speaker design.

THE SMD is the top of the range in this series and looks to be the one to beat with its unique design which offers incredible motor strength and a superb thermal power handling of 3500wrms.

There`s an Ascendant Audio subwoofer for every type of budget or type of bass.

In the pd format the LOUDEST ever single subwoofer boot install features a Mayhem 15" which was getting 3000wrms.
