The TD-4001 is of the rear compression design, which eliminates the resonance and phase distortion produced by a surround. It also eliminates cavity resonance interference, achieving very flat frequency response, extremely natural sound and superb definition.

2004年8月31日 · Having personally recently compared freshly diaphragmed 2441s to a pair of TAD 4001s, I can't recommend the 4001s highly enough. TAD TD4001 wins when mounted on an appropriate horn. For a matching horn and performance data, see my recent post in the Technical section. Sonicly the TAD 4001,s win.

The TD-4001 successfully achieves all the design objectives we set forth - very high efficiency, wide and perfectly flat response from 600Hz to 20kHz, and low distortion.

The TD-4001 is of the rear compression design, which eliminates the resonance and phase distortion produced by a surround. It also eliminates cavity resonance interference, achieving very flat frequency response, extremely natural sound and superb definition. A phasing plug helps smooth the response of extra high frequencies. Crossover.

2025年2月26日 · 回复 32# turboguy 我知道T版是玩TAD的老前辈，4001的确是16欧没错，不管是早期的高直流阻抗版本，还是后期的低直流阻抗版本，其实测交流阻抗都是16欧，这点香港萧生也清楚。 假货我也是近两年才遇见，正品音圈是铝线，细而密，工艺非常细致整齐，而假货是铜线，粗、梳，工艺十分粗糙，很明显的，肉眼就分辨得出，但问题很多人只看到铍振膜就收货，很少打开音圈检查~ 回复 32# turboguy 我知道T版是玩TAD的老前辈，4001的确是16欧没错，不 …
