DD Audio doesn’t offer a 5×7 or 6×8 speaker but we realize that there are several people out there that have these applications and really want to use a DD Audio driver. Well, don’t fret because we have the fix for this situation. The AP-5.2 is an adaptor plate that allows you to mount a 5.25” midrange driver such as our AW5.25 and a separate tweeter such as our AT28 in a factory 5×7 or 6×8 opening. Other products that the AP-5.2 works well with is our CS5.2 component set, CXS-5.2 coaxial, and T2 tweeter. If you have any more questions, contact us at firstname.lastname@example.org and we’ll get them answered for you!
