H1224-08 L18RNX/P
L18RNX/P is a 6,5” High Fidelity woofer with an injection moulded metal chassis, intended for bass reflex and transmission line designs.
Stiff, yet light aluminum cone and low loss rubber surround show no sign of the familiar 500-1500 Hz cone edge resonance and distortion assosiated with soft cones.
Large magnet system gives good transient response, and the bumped back plate together with the very long, and light weight copper clad aluminum voice coil allow for extreme coil excursion with low distortion.
Extremely stiff and stable injection moulded metal basket, keeps the critical components in perfect alignment.
Large windows in the basket both above and below the spider reduce sound reflection, air flow noise and cavity resonance to a minimum.
Frequency response

The frequency responses above show measured free field sound pressure in 0, 30, and 60 degrees angle using a 12L closed box. Input 2.83 Vrms, microphone distance 0.5m, normalized to SPL 1m.The dotted line is a calculated response in infinite baffle based on the parameters given for this specific driver. The impedance is measured in free air without baffle using a 2V sine signal.

原计划
原帖由 3l 于 2014-3-14 16:37:00 发表
预告：第二季，两分频三路，双中低音单元，两个中低音单元设计不同谐振频率的独立声腔，两声腔设置不同的反射管谐振频率......


温哥华的朋友BID了套H1224 + H1212，改计划，继续书架。

H1212-06 27TBFC/G

27TBFC/G is a High Definition metal dome tweeter with a wide, soft polymer surround and a rear chamber.

Aluminium/magnesium alloy diaphragm with pistonic behaviour throughout the audible frequency range, resulting in a good dispersion also above 10kHz.

A Hexagrid protects the diaphragm, and supports a phase plate which compensates for a slight axial roll off towards 20 kHz.

Sonomax surround for low resonance and excellent mechanical linearity.
Voice coil windings immersed in magnetic fluid increase short term power handling capacity and reduce the compression at high power levels.

Stiff and stable rear chamber with optimal acoustic damping allows the tweeter to be used with moderately low crossover frequencies.

Precision moulded chassis from glass fibre reinforced plastic, and its front design offers optimum radiation conditions.

今次妖都、温哥华同时行动，温哥华那边玩DIY，藕这边按标准产品出样。
妖都会用另一高音单元H1189-06 27TDFC



27TDFC is a High Definition precoated fabric dome tweeter with a wide, soft
polymer surround and a rear chamber.
Sonotex precoated fabric diaphragm with high consistency and excellent stability
against variations in air humidity.
Sonomax surround for low resonance and excellent mechanical linearity.
Voice coil windings immersed in magnetic fluid increase short term power handling
capacity and reduce the compression at high power levels.
Stiff and stable rear chamber with optimal acoustic damping allows the tweeter to be
used with moderately low crossover frequencies.
The chassis is precision moulded from glass fibre reinforced plastic, and its front
design offers optimum radiation conditions.

Frequency response

The frequency responses above show measured free field sound pressure in 0, 30, and 60 degrees, mounted in a 0.6m by 0.8m baffle. Input 2.83 Vrms, microphone distance 0.5m, normalized to SPL 1m. The impedance is measured without baffle using a 2V sine signal.

已开声的，搭手头现有的老古董H519慢火炖。

这箱体的反射管频率A1 flat, 反射管频率与箱体频率为一大三度音程。

用这鸟合并，声音相当银荡鸟。



HIFI何价？这台鸟合并的价钱，1999厂方定价 RMB 1800.




从巴洛克到摇滚、重金一窝端，如何？
