MK Sound, successors of the former Miller & Kreisel company, started with a "don't mess with success" philosophy. At first, it sold legacy products like the renowned 150 THX speakers, and introduced consumer products like the M Series that were previously available only to the professional market. More recently, MK Sound developed a new tweeter for its MPS 2510P and 1611P professional monitors. The new tweeter was developed in conjunction with Peerless of Denmark (now part of Tymphany), M & K's driver component partner for 34 years. MK has incorporated the new tweeter into its newest consumer speakers, the 950 series.
