SP2309W and AY511PA

Hi all,

I've had my SP2309W for a while now, and until recently have been using a bluray player surround system as my PC speakers (bluray player connected to the monitor  via HDMI, PC via DVI and xbox via VGA, with the xbox connected to the surround via toslink).  But, after moving house, the xbox and surround now live downstairs with the new TV, and I'm left looking for PC speakers. So, what I'm wonder is .. can I use the AY511PA on my SP2309W? As far as I can see, the mounting seems to be the same, and I know I'd have to use the power adapter, but I can't find anything other than a few ebay listings that say they're compatible.

Any help would be greatly appreciated, as I'd prefer the AY511PA to the AX510PA.

Thanks in advance.
