[QUOTE="Andy Turner, post: 204706, member: 10677"] Mark, Thank you for the measurements and input. During the measurements I found out that the calibration file for my second mic(UMC8000) was not correct. After changing it I found that my measurements started looking a bit more like the ones on the BMS site and yours. (Thanks) My old RTA is maybe broken. Here is the difference between the RTA and UMC(VHF=Green): [ATTACH=JSON]204707.vB5-nodeid=204707[/ATTACH] UMC mic in Smaart: [ATTACH=JSON]204708.vB5-nodeid=204708[/ATTACH] With the new measurements in place, I made some quick settings with Smaart and found the sound a lot more natural. Adding 3-4 db in the 4.8K area, Lowering 3K and 11.5K 3db. Next step is trying to copy the B&K 'optimum curve' [URL]https://www.bksv.com/media/doc/17-197.pdf[/URL] - reason being that I think the sound with a linear FR is very bright. - And a new 'better' mic with a correct calibration file :0) Comments are very welcome. - Andy [/QUOTE]
