Loudspeaker with insignificant THD.
Hi,
I am looking for a loudspeaker with THD less than -50dB. I understand that lower the THD, more the linear the loudspeaker becomes. I have this requirement in testing of echo cancellation algorithm in real time. could somebody suggest. Thanks, Prabhu. |

I have this requirement in testing of echo cancellation algorithm in real time. could somebody suggest. You might want to look into the NHT Xd system. Their whole raison d'etre is low distortion; system specs 0.00315% THD, which equates to something like -130dB. They don't sound too bad either. However, no independent measurements exist, and basic physics suggests that the quoted figures are 'unlikely'.................. -- Stewart Pinkerton | Music is Art - Audio is Engineering |

This is true. OTOH this NHT system is the first of a new wave of speakers with dedicated dsp control which may be the next breakthrough technology advance. That's fine, but frequency response is only half of the audible characteristics of speakers. If their spatial pattern sucks, then the speakers will suck, no matter WHAT their frequency response. Do they know that? Gary Eickmeier |
