That way I have some nice gadgets lying around and I try to make use of them. In my office I have a Beomaster 4500 + Beogram CD4500 with Beovox 3000 flat-panel speakers <img src="http://forum.beoworld.org/emoticons/10.gif" alt="Embarrassed" /> The speakers are fine but they lack in bass as of their size and type. </p> <p>I have an excellent Genelec active subfoower available so I&#39;d like to connect it to the system. I have done it by taking the signal from the powerlink socket (combining L and R-channels) but this causes the main speakers to work in mono, too! I can run the system fine if I only take one channel to the sub (listening to it right now, sounds absolutely fantastic!) but I guess it&#39;s should have both channels there. Any ideas?</p><div style="clear:both;"></div>
