Get in touch with Rock Video, ask for James 019-6633638 or rockav@pd.jaring.my. They have all sort of crazy stuffs. Speakers taller than me an you. AV systems, disco sound systems, VOD karaoke systems and so on. A month ago, just recomended them to a customers of mine, who just opne a health spa center at Midvalley. Did the excact type of in-ceiling speakers like the one that you wants.
