Re: 60 Degree DIY Mid HiA lot of the people I see using Smaart don’t really understand exactly what they are measuring.If you use an FFT with a time window that’s big enough to capture the low frequencies you are usually capturing other stuff you don’t want that mucks up your measurement.There are basically two solutions – measure it in an anechoic chamber – or measure it a long way away from any boundary’s (12ft in the air or more) where the mic is relatively close (6 ft) to the speaker. Note: this is a mid-Hi box operating from 100Hz up (100Hz wave length = 11.15ft, 10ms per cycle). For low frequency you can place the mic on the ground.As a practical solution your setup with the ground sloping away looks great.
