My klangfilm 10" driver frequency rang from 40 hz to 8k hz on my current setting without cross over and direct connect to amp output. The Pioneer ribbon 7III tweeter add for higher frequency above 10k hz at 1st order wiht 0.1 u USSR oil paper capacitor. The frequency db slope is only depend on the drivers itself.

國內朋友的Rullit Aero 8全頻試驗障板

我好想有機會可以一聽 Rullit Atellier 嘅單元，實在太少人擁有

Rullit單元開始多人玩, 大陸已經有人玩了, 話好正！

Tony 兄，你認識他們嗎？近香港嗎？

welborne兄,

他們在四川和石家莊。 我都想聽。

我同Oleg有聯絡, 他說最全面的全頻單元是12吋鋼磁。

喇叭背後加了紙蛋盤，減少撞声。

簡單背後。

祝各位知音中秋節快樂！

Merry Christmas to all of you ^^

To you too Welborne!

最近加上一隻RCA alnico 高音，4ohm，用4.7uF电容在大約5k分頻，減少klangfilm全音喇叭高音量，声音比以前清咗，但很醜樣！

Just come across a thread. Not sure if it is true ! For friendly information only.

Last month, I am lucky that can arrange a weekend afternoon to listen a German open baffle system, Bastanis' Mandala! The sonic, dynamic, details and sound stage are so impressive that get beyond all traditional cabinet speakers.

I heard that a Bastanis showroom will open in Hong Kong soon, can't wait for it !

Yes, the man in charge Andy is my friend and his upcoming showroom will be in kwai hing, only 3 blocks away from my den, so there would be two Bastanis system in Kwai Hing ;)

Welborne, your Mandala looks like a harp! *^▁^*

打橫擺就變古箏啦！

嘩！你自己 索色?

係呀！但由於第一次做，效果不夠好，但之後又太賴惰冇再執翻靚佢，只想聽歌。相片比實物好看好多
