In Reply to: SF Guarneri Memento's terrible measurements posted by Pinkus on May 7, 2007 at 19:18:55:
The FR measurements are disappointing as FR is for sure an important component of a speaker getting the correct tonality of instruments. However, it is unclear if this is only an on-axis response or is it a an integrated response over a wide horizontal listening window. Perhaps the power response or an in-room response would show a much flatter response than the one reported.If the speaker is in fact a 1st order x-over design then one can expect some pretty large off-axis variation in FR unless the drivers are VERY close together. My guess is that the dips fill in off-axis and the peak will for sure flatten out because the Ring radiator tweeter doesn't have nearly as broad a dispersion as the Esotar dome tweeter. This can be readily seen with other speakers using this kind of tweeter. My guess is that this speaker is not designed to have the speakers pointing right at your ears for flattest response and relies on the room siginficantly to smooth out the response. Not how I would choose to do it because I think designing to limit the room influence gives a more broadly applicable speaker.
In addition to FR though are things like distortion of drivers, compression, both thermal and dynamic and driver and cabinet self-noise. All of these things affect perceived tonal balance and transparency. None of these things are completely clear from this one measurement either. In stereophile JA measures each driver individually and then it is possible to see if cone break up is evident (as speculated here by the guy making the measurements).
