"Precise sound creation and overwhelming power. Designed specifically for your vehicle, the M&M DESIGN MX series + PCD-1 will awaken your sound."

Improved sound quality with vehicle specific design.
When considering the appropriate material to use for the inner baffle, duralumin aluminum is inevitably chosen if performance is important.
M&M Design's ``MX Series Inner Baffle Base'' is made from solid duralumin aluminum, which is highly rigid and non-magnetic, and is machined one by one using a CNC machining center.
Up until now, inner baffles have been made of wood such as MDF or plywood, but they sometimes rot due to water entering the inside of the door. We have succeeded in completely preventing this problem by using aluminum.
