The K40T surround box is upgraded from K4T surround speakers. K4T has already been used in professional recording studios due to its excellent performance. Miller & Kreisel began to build multi-channel monitoring systems for small recording studios with K5 and K4T since 2004. In addition, K4T is one of Miller & Kreisel’s speakers that has made the valuable Tripole Surround technology more popular. Like the K50, the K40T has a slimmer cabinet. It also uses a 1-inch silk-film tweeter and a 4-inch glass fiber woofer, allowing the Movie 5.1 system to get the best multi-channel performance.
