Test Bench: SEAS E0060-08/06 6.5” King Coax

The driver featured in this Test Bench is the new E0060-08/06 6.5 “King Coax” from SEAS. Recognized for several years for its high-performance coaxial midrange/tweeter drivers, SEAS developed this new driver at the request of a studio monitor customer who wanted a compact three-way monitor and asked SEAS to develop a midrange + tweeter coax. The King Coax received its name from the copper ring under the tweeter, which resembled the look of a crown. This article was originally published in Voice Coil, June 2017.

Test Bench: Accuton C30-6-358 High-End Tweeter

The samples for this Test Bench came from respected German home/car audio OEM transducer manufacturer Accuton. I received the Accuton C30-6-358, its new “Cell Concept” neodymium motor ceramic diaphragm 30 mm tweeter. The Accuton C30-6-358 is an interesting tweeter for several reasons. The mounting system, which is part of the “Cell Concept,” is definitely unique, with its proprietary clapping mechanism. This article was originally published in Voice Coil, April 2017.
