I'd like to know what 'plastic' and 'inert' mean in terms of the response. benhttps://www.blogger.com/profile/13835034425198648089noreply@blogger.comtag:blogger.com,1999:blog-8689487740107692135.post-32562724255816493812012-08-14T20:01:50.930-07:002012-08-14T20:01:50.930-07:00Dave, at the moment, R&D on this one consists ...Dave, at the moment, R&D on this one consists of the very scientific knock test, which suits the budget for now. It's not ideal but it does give a window into the sonics. You hear the expected plastic sound, lacking in stiffness but having a degree of damping. After about 3 layers as shown, the weight is increase from about 240 grams to 540 and now subjectively it sounds more inert than 18mm MDF. So the point of the exercise is to avoid the waveguide becoming a bottleneck. I believe it has been achieved. <br /><br />Down the track I'd like to do some proper measurements - one of many things on my to do list!

Got any measu..."improve the performance"<br /><br />Got any measurements?<br /><br />Not because I think your claim is invalid without them .... Just because I'm interested, and am a sucker for a pretty graph ;-)<br />davehttps://www.blogger.com/profile/04015826686468374161noreply@blogger.com
