О работе

M-Audio Studiophile Av30
Been using these speakers for a year or two, can't really remember. They had a bug which I later discovered which was also reported by other users on their bigger siblings Av40's. If only I wasn't lazy and returned them for another pair... But I could never be bothered with returns and postage unless items are completely faulty ( Read more... )
