It sounds as though the voice coil is rubbing and this will fail if not done properly. Recone Lab can do this and I dare say Martin (Dillen) would like a chance to see a 3800 as well!<br /><div style="clear:both;"></div>https://archivedforum.beoworld.org:443/forums/thread/17106.aspxSun, 27 May 2007 00:37:09 GMT41a2a90c-3a1e-4bd3-b144-3883695a7f38:17106camshaft0https://archivedforum.beoworld.org:443/forums/thread/17106.aspxhttps://archivedforum.beoworld.org:443/forums/commentrss.aspx?SectionID=13&PostID=17106<p>Hey guys,</p><p>I hooked up my 3800&#39;s after they&#39;ve been unused for quite a few years.&nbsp; On one though the subwoofer sounds distorted.&nbsp; When I press the cone I can hear the coil rubbing, and if I press upward the rubbing stops.&nbsp; So I&#39;m pretty sure the rubber surround has just sagged with age causing the coil to rub.&nbsp; Has anyone tried to fix something like this before?&nbsp; And how hard is it to replace a non-foam surround?&nbsp; (I&#39;ve only done foam ones before).</p><p>&nbsp;</p><p>Thanks guys,</p><p>Austin&nbsp;</p><div style="clear:both;"></div>
