These speakers are the pinnacle of MTXs design and engineering team. They are designed solely for high end home theaters where accurate and realistic audio reproduction is of the highest priority. They feature a pivoting cloth tweeter and midrange, unlike other adjustable tweeters and midrange systems that use an eye ball mounting system; the MTX design utilizes a adjustable speaker plate to reduce refraction. The woofer is formed from glass fiber allowing it to reach 45 Hz.
