DIY雙十仔: P.16 update

djaddy

終於收到雙十仔單元.

More than 10 yrs ago, I have made sub-woofers from Peerless, Vifa and Jaycar drivers. After careful consideration, I decided to buy HiVi SP10. Many of the DIYers from overseas use this driver. Reports are very good. One must take note that this driver is no longer in production for the China market. It looks & sound a lot like Sunfire. I am looking forward in hearing the finished product.

中國的 HI-VI  千幾蚊一個。
不錯，整密閉箱可以發揮的威力。
Power AMP最少都要500W，低阻抗的，難喂飽！

The 2 x sub-woofer enclosures (boxes) are currently being made. It will take around 2 more weeks to finish.
