The MAX offers a new standard in portable speakers with the introduction of the ceramic tweeter. The quality of sound produced from any speaker depends largely on the tweeter material and after months of research, trials and prototype development, the engineering team at Xmi Pte Ltd found that ceramic was the most suitable material to bring the X-mini™ sound to the next level. The ceramic tweeter brings about several advantages. As compared to aluminum tweeters, the ceramic ones can produce a wider frequency range covering higher and lower sounds. As a result of that, the distortion of sound is also much reduced because the ceramic tweeter is able to withstand high and low frequencies without producing any cracks in the sound.
