Radian Audio Engineering, Inc. was founded in 1988 with the mission of manufacturing great sounding, high quality loudspeakers at affordable prices. Radian’s initial offerings were replacement compression driver diaphragms. The diaphragms took off so well that it wasn’t long before the company was making compression drivers.

Several major loudspeaker manufacturers quickly identified Radian as an important source for their compression driver needs and became O.E.M. customers. Coaxial loudspeakers were introduced shortly thereafter, followed by woofers and finally, complete loudspeaker systems.

Today, Radian Audio, based in Pomona, California is a major player in the O.E.M. loudspeaker compression driver business, the sound contractor/fixed installation market and the portable/tour sound industry. With over three decades of success under its belt, Radian Audio proudly enters its fourth decade with its eye toward the future.

Radian Audio Engineering is known for some of the best sounding large format compression drivers that deliver high-performance “behind the screens” in the finest soffit studio monitors, concert sound arrays and audiophile speaker systems. Radian drivers range from 1¾”, 2”, 3”, and 4”, and while there are quite a few musical smaller format drivers, and a couple of decent 3”, smooth and clean 4” drivers remains a “delicacy”. Radian does not “kiss and tell” nor competes with their OEM and ODM customers in that they only produce the drivers and stay out of the speaker system end of the business.
   
Radian was founded in 1988 with the development of the company’s unique aluminum alloy (aluminum, titanium, and copper), spin-forming and annealing processes for diaphragms. Initial offerings were upgrade replacement compression driver diaphragms for Altec, JBL, and Emilar and other leading brands of the time. The product line expanded to complete compression drivers and eventually pro-sound woofers and coaxials.
   
In 2017, under new ownership and new management, the company embarked on a quest to reestablish Radian exclusively as an OEM and ODM supplier of drivers and speaker components.
   
Operating independently as a proud Californian speaker manufacturer, Radian has expanded its comprehensive product line of coaxial drivers and launched a new generation of high power ribbon planar tweeters which continues to expand with dedicated models targeting also residential installation and studio monitors. Radian reinforced its neodymium compression driver product line with its flagship 950/951 Neo 4” with the option of aluminum alloy or (Materion) beryllium with 5 slit phase plug. In fact, Radian’s long relationship with Materion as a supplier of Truextent premium acoustic beryllium domes, cones and diaphragm assemblies continues to strengthen. And under the new management, Radian also initiated a development program using TeXtreme TPCD carbon fiber diaphragm versions of its various drivers and diaphragms.
   
Today, Radian Audio operates based out of Pomona, California, with modern facilities from where the company is ready to expand its business globally. Over the last three years, under the new management, several major loudspeaker brands have become Radian OEM customers and the company is quickly expanding its catalog to serve different market verticals, from home audio to the most powerful high-quality sound reinforcement and performance systems, always with a differentiator in well engineered solutions, with consistent build quality, and better-sounding products.
