Illusion Audio speakers are thin and light weight while maintaining the performance of full size heavyweight speakers. Acoustic output is often double or higher than other thin speakers. The woofers are designed to use smaller than normal cabinet volumes while maintaining full bass extension and loudness. Tweeters are optimized for lowest distortion with lower crossover frequencies for better sound stage imaging. All materials used in the construction are professional grade for extreme durability and to maintain lowest distortion. Several proprietary design features are incorporated to maximize packaging efficiency, sound quality and durability.
