The Timepiece goes up to 16 kHz at +/- 2 db, so probably only at most to 18 kHz at +/- 3 db.
Timepiece goes up to 16 kHz at +/- 2 db, so probably only at most to 18 kHz at +/- 3 db. The Sp 25 in comparison goes up to 25 kHz (+/- 3 db). Despite (most, if not all,) humans not being able to hear past 20 kHz, studies have shown that frequencies 20 kHz and up do effect the frequencies we do hear. Oftentimes these frequencies are associated with that audible airy quality. This can be important in properly reproducing the sustain, harmonics, and overtones of certain instruments. If Bob does answer here, I would be curious to know what frequency range the treble settings effect. The Timepiece looks fairly flat in the highs, except a peak around 10 kHz, and up to where the highs taper off...based on the specs provided. Also, are these specs based on the flat setting?
more data points for the treble discussion - my meret's are rated to 22khz, the proac ref-8 sigs to 30khz, the swan m1.2's to 25khz. zu monitors (which seem to be a bit lacking in the "air" & detail dept - their only weak point, imo), are also rated to 25khz...doug s.
Redbook CD's have a glass ceiling at 22050hz and the wave shapes (even with noise shaping) above 14K on redbook are little to be desired.
Any loudspeaker with accurate time placement up to around 12K will display musicality galore and even though some speakers tout 50K response, no speaker made can do it outside of a 10 degree dispertion at best.
I used to feel that accurate presentation to 30K was a must. Even with the source matierial I have and use (flat beyond 30K) I still fell that nothing is lost with the SP tech speakers when it comes to reproducing musicality. audiojerry would have certainly commented on a "lack" or a "need" if the sp's were deficeint up there. I find the source makes the difference and actually, I miss nothing in music with the sp's.
I do think there is certainly more to it than just extension. A pair of Swans Diva's I own has plenty of air, despite only going up to 20 kHz, although it seems partly artificial. Also, I agree about the Zu's. The Druid's did not seem to be able to do so either. Oddly enough, their Rune's did appear to properly recreate the air and sustain. I know on the Druid's this was done intentonally. This tells me that part of it is still definitely in the design and implementation.
re: the druids, it is interesting to find that i'm not hearing things! it's really too bad, imo - they really have fantastic dynamics & imaging. if it weren't for this lack of air & detail,
Quotere: the druids, it is interesting to find that i'm not hearing things! it's really too bad, imo - they really have fantastic dynamics & imaging. if it weren't for this lack of air & detail, I auditioned one of the first pair of Druids, and I felt the same about dynamics and imaging...and their ability to play at very high spl. But I don't think lack of air was entirely the problem - they were somewhat hard on the ears and caused listening fatigue quickly....
doug s., so many speakers, so little time...
I also had the original druids, & can agree with the "hard on the ears" comment. After some long break-in, they did soften up. I have since upgraded to the Druid 2 & they are definitely no longer hard on the ears. As far as lack of air & detail, IMHO I don't find that is the case at all. I think that the Druid 2 is one of the most detailed speakers I have listened to. That being said, I have not listened to the monitor version, so I can't comment on it. I do have the Druid 2 center channel (similar to the monitor), & that speaker is excellent for dynamics & detail in even the most demanding movies.
Sa-dono, did you listen to the floor standers too, or just the monitors? This is where there could be some differences between the two speakers. Also which speaker cables were you using? & which connection the spades or the 8 pole plug. The druids are very sensitive, & they easily demonstrate the differences in speaker cables & the connecton. I am curently using the Ibis & the 8 pole connection. I did do an A/B with 2 sets of WAX with the different connections. The spades sounded compressed compaired to the 8 pole connection. Later
