Re: HSU VTF-15H In room measurements - All 15 configurations
That's easily flat enough for loudspeaker measurements, and what variations there are can be canceled out by calibrating your sound card. The low end rolloff is something which is designed-in, and is always done by manufacturers to avoid amplifying quiescent DC from the microphone or DC offsets within the circuitry. In your sound card, its a bit higher in frequency than usual since they don't anticipate measurement microphones to be used. It would be a relatively simple matter for someone who knows what they're doing to move that frequency much lower to restore most of that low end, but its not worth the trouble since you can calibrate the card.
