We are driven by a desire for excellence and expect nothing less than to turn the next page in mainstream loudspeaker design. We offer many high quality loudspeakers in kit form. We have high quality crossover components and accessories for any project. We have our own proprietary line of drivers that are used in our designs. We also provide a wide range of design services from complete commercial product line design to assistance with individual custom products and upgrades.
