Ναι, ε?

"But, while on the surface the NS10 was unexceptional, it perhaps by chance combined technical features and performance characteristics that uniquely suited it to the nearfield monitor application and some unknown recording engineer first discovered it worked well in the role (Who was the first? Does anybody know?). The rest, as they say, is clich. The happy accident of the NS10s characteristics wasnt widely appreciated at all at the time, and perhaps still isnt now, but was demonstrated very clearly in a paper presented to the Institute of Acoustics by Philip Newell, Keith Holland and Julius Newell in 2001 and published in the last [] issue of Studio Sound magazine []. How ironic that the first serious attempt at working out why the NS10 worked so well as a monitor happened in the same year that it was discontinued.
The Newell/Holland paper The Yamaha NS10 Twenty Years A Reference Monitor. Why? sets the NS10s in the context of 35 other nearfield monitor speakers by measuring each ones amplitude response, harmonic distortion, step response, and amplitude response waterfall (a measure of how well a speaker performs in the time domain) [Much of this was drawn from the monitor tests we ran in Studio Sound. Ed]. Newell and Holland argued that a good result in the last three of these characteristics in particular is vital if a speaker is to perform well as a monitor because they describe how accurately it is able to communicate whats actually inherent in the signal (as opposed to speaker artefact) in whats finally perceived by the listener. Of the 36 speakers tested, the NS10 effectively came top. Its distortion levels were among the lowest, its step response was the quickest and its waterfall was the cleanest."
Και παρακάτω:
"The NS10 had one other feature that I believe is vital for a musically accurate monitor it was a closed-box design (or rather, it wasnt a reflex design). Recent work, again by Newell and Holland and published in this very magazine (Measuring low frequency response accuracy, V4.3) has shown how reflex loaded speakers, while undoubtedly offering extended low frequency bandwidth, are inherently flawed when assessed in terms of signal intelligibility criteria. The flaw comes not only from the inherently poor time-domain response of reflex loading (a typical reflex loaded speaker will introduce a delay to low frequencies of around 15ms or more see Figure 4), but from the reflex loading mechanism itself introducing distortion, compression and noise."
Αυτό δεν σημαίνει ότι εν έτει 2008 το NS10 είναι η βέλτιστη επιλογή. Τα διδάγματα όμως που βγαίνουν από την δημοφιλία του επί δεκαετίες - και από τους λόγους αυτής της δημοφιλίας - ισχύουν και τώρα όπως και τότε. Όσο για τα Quad, τα χρησιμοποιεί ο Tony Faulkner. Δεν θα τον έλεγα άσχετο
Αν θες, μπορείς να τον πεις εσύ. Και να υποστείς τις συνέπειες!
