This subject comes up 3 or 4 times a year.
Resonance Inc. is a holding company owned by the Langford family.
Resonance owns our AQ/DD build facility and domain names.
DD is owned and operated by my son Jassa and his wife Vicki Langford.
AQ is owned and operated by DJ Langford.
Both companies are independant of each other.
Subwoofer designs are not the same nor are the motor designs
The AQ HDC3 series share the same basket as some DD series
AQ/DD soft parts are not shared
AQ amplifiers are made in South Korea
AQ comp sets are made in Germany
Any AQ sub with a "C" in the model name denotes the sub assemblies were made in China and final assembly and QC are done at Resonance's build facility in OKC.
The SD2 series is still made in OKC but in the not to distant future it also will have a "C" in its model name.
AQ is around for the long haul but ownership and operation will be passed on to my Grandson, Charn Langford, when I get tired of doing this. Charn has had an active part in every aspect of the family business most of his life and knows the business from the bottom up.
AQ products are "drop shipped" from Resonance warehouse in OKC.
if i remember.. dd is made here? (sorry, dont like dd, and dont follow them)
