Masjid Speakers....

I was wondering if anyone can help me out there? I've been given the responsibilty of buying new speakers for masjid, what I wanted to know if anyone knows where to buy decent speakers from, or even if anyone can tell me what speakers they have in their masjid i.e name and model so I can search them online to buy. What I am looking for is the tall white speakers you find in the masjids these days. Any help will be appreciated. Please help

Can't really help you there.
But whatever you buy, please buy a very decent one. Nothing is worse than listening to adzhan or qur'an recitation from very loud but really horrible speakers where the sound seems to come from screaming throat with very bad laryngitis. It would irritate a lot of people who listen to it, pretty much defeating the purpose of having loudspeakers in the first place.
