The new Meadowlark speakers are coherent. They are fully active with onboard DAC and they have amps for each driver. The older Meadowlark offerings were a more traditional coherent speaker. Like the newer Meadowlark, the Gaylen Sanders are fully active coherent speakers.I believe the Kii speakers are also.
Others are Dunlavy, Ascendo, Green Mountain Audio, Intuitive Design, Essence, and Mosaic Acoustics.
