diy音箱是不容易的

这个可以一试，但是519应该不可以胜任，我是说一阶，太多低频进入高音不太妙。

这点也有道理, 因为分得低, 还是三阶吧! [s:19]

X3-06 EXOTIC T35   
The Exotic T35 is a classic dome midrange tweeter with high sensitivity and a smooth, extended frequency response.

A coated fabric dome with integral surround manufactured by Dr. K. Müller in Germany  ensures excellent performance and consistency. This supplier was among the first in the world to offer fabric dome diaphragms, and did produce the diaphragm for the famous 1.5” Dome Tweeter H087, developed by Seas in 1968.

A high efficiency Alnico V ring magnet in a carefully designed system contributes to high sensitivity and low distortion. A large and well damped cavity in the pole ensures a low resonance frequency and smooth response.

A generously underhung 35mm voice coil wound from copper-clad aluminum wire further enhances the sensitivity. Flexible lead-out wires and venting holes in the aluminum coil former help reduce noise to a minimum.

A large diameter 7mm thick precision machined aluminum front plate with moderate horn loading ensures linear frequency response and represents an extremely stable platform for the magnet system and the moving parts.


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.

X2-08 EXOTIC W8   
The Exotic W8 is an 8 inch woofer-midrange driver designed for smooth, wide frequency response, high sensitivity and low distortion.

The special paper cone is embedded with papyrus fibres to optimize stiffness and damping.

A special foam rubber surround reduces mass by 40% compared to conventional rubber surrounds, resulting in higher sensitivity and excellent damping properties. Unlike most plastic foam materials, this material is stable and will offer decades of trouble-free operation.

A new and proprietary spider design dramatically improves the performance of this critical suspension part. By combining an extremely open weave with a new resin formulation, all noises normally generated by the friction of the threads rubbing together are virtually eliminated. Additionally, the open weave is highly acoustically transparent, minimizing the reflections and resonances associated with conventional spider designs.

A high temperature copper voice coil is wound on a rigid, non-conductive glass fibre former.
High quality H2 lead-out wires eliminate noise due to roping and resonances.

The magnet system uses an Alnico V ring magnet for high sensitivity and excellent stability.
Massive copper rings above and below the magnet gap lower distortion due to eddy currents and flux modulation. A hand-turned phase plug made from ash offers optimal radiation conditions for the critical mid frequency band.

A stiff and stable injection moulded zinc basket keeps the critical components in perfect alignment. Generous windows both above and below the spider reduce sound reflection, air flow noise and cavity resonances to a minimum.


Frequency response

The frequency responses above show measured free field sound pressure in 0, 30, and 60 degrees angle using a 60L 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.

这个喇叭尺寸比较大，看样子似乎贵价呀?

分频不易.

褒了几天下来,中低混浊现象几乎消失了,
高音清晰不少, 再等段时间看看要不要换高音.
REVEL 喇叭确实不错

为什么不弄个中音呢？   高音负载较低的频率，细腻全无。

飞师兄, 报道一下最新情况?
还有, 帮我一个忙, 坛内有屁精风麟, 贱种Willers眼红我在挣钱, 请说说我代劳设计分频器是义务的, 一文钱也没收过, 谢谢你~ [s:89]

自由心情

其实diy就是要不断探索，像您这样的还是。。。

886兄在常平,我在塘夏,  与886兄素未谋面, 但是老兄一直热情的指导,免费帮忙设计分频器,
我除了感谢之外并无其他,褒了这么久, 现在的箱子已经能够满足我的听音要求了.
在现实生活中,也经常碰到一些人自以为高人一筹, 从不认同其他人, 但是他们混得好象并不是出人头地, 这就能说明一些问题了,所以老兄不必太计较了, 一笑了之...
附件是这个箱子的图,再看看

飞师兄, 多谢你帮我澄清~[s:89]
那你还现用 H519?   没怪声?  正常?
我听有用 9500 出厚声, 自己盘算; 也请翻看, 不少坛中高手助你拳!

大家小心这个澳门垃圾，曾指天发誓说不在家电卖东西，结果却被抓猪尾巴，遭人耻笑。

现在还用５１９，但是声音真的还不错了，等有空买对好一些的高音再试试，应该有提高的空间．

hewangfei

老兄不必如此激动，　即使卖点东西也无大碍吧？只要不卖假冒伪劣对得起良心就可以了，
