So far, my PC speakers were type "stereo - classic" banal sound without any effect ... Anyway, recently my hugely pregnant sizzled and became inaudible. Well decide to redeem myself pregnant and having read hundreds of positive opinion on this set logitech x-530, I decided me to buy it, especially amazon offers the best prices on the web for this set and is probably the only one not to charge the shipping cost of such a product (almost 8 kilos!). Finally this morning I received it and 10 minutes later here I am listening to the music I had never perceived as such! A clear, impressive sound, deep bass, an integrated amplifier ... It is the best! Just for info (many are problem): the green cable plugs into the green socket, the black cable on blue and orange socket on the pink cable outlet. It must be paid (Control Panel) on your sound "Surround 5.1" and that's it! The dvd-console adapter is provided. Provide all the same RCA extension for left rear speaker (is everywhere at low cost). Otherwise I am delighted with my purchase. I recommend it! [DVD Review: kill bill volume 1 / test music: DJ Dero - dero's illusion / Bo basic instinct]
