请教用过seasH624的同学

zgtsang

请教各位用seas的H624做中音怎么样啊，我的低音是双十寸，8 OHM, 90 db,当初买H624是听介绍说人声不错，且看他的灵敏度有92db合适配我的双十寸90 db低音
vifa P13 和 seas 149中频肯定好过H624，但灵敏度都小于87db. 现在看10寸的低音随便抓一个也过90db 了，怎么办？

昨天把H624暂装一15L的箱子，晕，低音那个差。。。。。460块啊，心疼，低音感觉还不如我那180块的惠威6寸半。是不是哪出问题了，谁有在用H624

H624的功率比较小，如果只是拿来做中音是不是功率问题就解决了？毕竟大部分功率集中在低频端。是不是这么理解？

去年买了3套做AV前置和中置。晕

zgtsang

刚看到网上有人说H624是专为汽车音响设计的。倒！ 原来高灵敏度都是以牺牲音质实现的，以后高灵敏度的喇叭看都不看了

zgtsang

是的是的！ 唉，怎么汽车喇叭也卖这么贵，该死的seas.

好在人声还不错，就做中音吧，反正用来做AV音箱看看电影。安慰啦！

"用6.5寸做中音,是一个错误的设计."

你说的容易，给我找几个过90db的4-5寸的中音锥盆中音看看，有也是专用的吧，价钱上天了。 知道吗，这叫compromise, 除非你愿意在低音上串个电阻。
再说你这个喇叭也不便宜吧

好像JBL也有用6.5寸兼中频的

看起来是不错，价钱也同H624 146， 毕竟是专用中频，灵敏度如何？

The MCA15RLY is a 15 cm (5’’) cone driver, developed for use as high
quality midrange unit.
The classical coated paper cone gives a smooth extended frequency
response with a controlled roll off. The large magnet system, together
with the light cone give high sensitivity with low distortion and good
transient response.
The 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 refl ection, air
fl ow noise and cavity resonance to a minimum.
The frequency responses above show measured free fi eld sound pressure in 0, 30, and 60 degrees angle using a 20L closed box. Input
2.83 VRMS, microphone distance 0.5m, normalized to SPL 1m.The dotted line is a calculated response in infi nite baffl e
based on the parameters given for this specifi c driver. The impedance is measured in free air without baffl e using a 2V
sine signal.

89.5db  还行

我们是求同存异。

昨天调整了音孔和吸音棉，有所改善，虽然低频比期望的差点，整体上H624也不浪得虚名。哈哈，谢谢各位同学参与讨论。
