Hi

Just sharing the measurements which I took this week and the calibration done using minidsp.

The measurements were done from the listening position using umik1 and the REW software. The speakers are kept below the TV in the living room with no room treatment except a carpet on the floor.

Measurements were done for the KEF LS50 Meta L & R speakers individually and then the Wharfedale sub D10.

The results are as follows:

Combined effect of final test signal with LEFT+ RIGHT +SUB:

In my opinion the trouble was more below 100 hz given the spikes in the sub.

The result is a more balanced response and better soundstage / imaging. Also some of the more suppressed frequencies have a breathing space as compared to the earlier results.

As always happy to note your comments and suggestions.
