With the correct speaker type selected on the BV7 - as well as reduced bass and low speaker level - there is still an &quot;interference&quot; sound through the speakers at the lower range. I first heard it with a film that had a low rumble - turning the volume down lessens the problem.</p> <p>Confirmed its not the signal by setting speaker 1 - and the sound (left &amp; right) through the center 7.1 speaker is fine. The interference sound is also there on the BV7 speaker setup page (not as pronounced as its not such a bass sound).</p> <p>Any thoughts ? Or shall i just get a man in to the setup properly on the BV7 (i did it myself) which may resolve it - or at least find out if i&#39;ve got a problem with my lab 6000&#39;s.</p> <p>BTW Overjoyed with my BV7-40 - I went for the low stand to disguise the size a bit. Looks great and very happy !!&nbsp;</p><div style="clear:both;"></div>
