are we close to the best possible drivers? :|

I agree totally about the need for better drivers rather than more but that doesn't necessarily mean taking the dynamic range higher. 20hz is a bit slack though. good point about the SMD crossovers though Stikk; 2 is enough; 3 quality drivers with well picked crossover points should be enough for any IEM. |

E.A.R Z5 Monitors Frequency Range: 20Hz-18KHz* Nominal Impedance at 1KHz: 68Hz* Sensitivity at 1KHz: 155dB* Noise Isolation: 24dB +/- 2dB Input Connection: 1/8" (3.5mm) Gold Plated Jack Costs: $1000.00/set The Z5 is the ultimate in music monitor systems. It incorporates a balanced dual armature driver for your low end frequencies, a single mid driver and a dual tweeter driver to handle the high frequency tones. There are an additional two crossovers on the dual drivers that makes this unique design a definite studio quality performance and surround sound feeling monitor system.

The main problem is not if we can or not ear that high but consider that the stated freq is the limit for them, but maybe the actual roll off will begin far before that, if they rated 16, maybe they can not even achieve 14 or 12 at full extension, and those are indeed inside the old man audible spectrum... Probably there is not too much musical info at that freq, same as lowers, but some harmonics or whatever, that maybe is what gives you the natural sound, in reality the real musical freq spectrum is far above 20KHz for mainly all instruments...I do not know for sure what is, but the fact is that none of them sounded right to me, the high freq sounds fake and unnatural, and maybe is due to another reason and I'm blaming the cut of the freq for that, I do not know for sure, but the coincidence is that all of them are alike regarding the way they sounded, and all of them cut the freq the same way around the same figures... |
