The Near-Field-Scanner 3D (NFS) offers a fully automated acoustic measurement of direct sound radiated from the source under test. ![]() Manufacturer’s information can be found here.Īpproximate retail price for these is about $300/pair USD.ĬTA-2034 (SPINORAMA) and Accompanying DataĪll data collected using Klippel’s Near-Field Scanner. Moreso, this is information for those who prefer “just the facts” and prefer to have the data without the filler.
