Wee Boon has sold the speakers and wrote me a thank you email.
"Thank you so much for your help in generating some interest from 972 listeners during your zuiai528 program segment on Thursday evening. I have sold my speakers to someone staying in Choa Chu Kang, at half the price (S$40) I had offered. Well! I am just delighted to have it removed from my house, which occupy space. Pls kindly help me to tag my item in the blog as "item sold" so there will not be any more people calling me. Thanks & appreciate. Btw, I like this segment very much as it seems to be more effective than some other websites offering similar services, such as ebay. Your program sure has the potential to reach more people, to the masses. Great job & pls continue to keep up the good work. 谢谢。"
