Somebody posted that to the Stereophile forum a few years back, and I enjoyed it very much. I haven't seen The Matrix, but I probably should. I've heard great things about it. I guess I'd better post something on-topic. :) My audio philosophy is to get maximum "bang for buck" by avoiding high-end audio equipment, and instead use a combination of pro audio, consumer A/V and DIY equipment. Source = SB Touch Speakers = JBL LSR6332 pro monitors I've become interested in the multiple subwoofer technique advocated by Earl Geddes and others. You can find out more about the multi-sub technique from '*_the_blog_of_poster_DS-21_*' (http://seriousaudioblog.blogspot.com/2012/05/two-great-articles-on-multiple.html). Current plans are to do DIY subs, with 4 drivers having individual amplifier channels and different low-pass filters on each one. Earl Geddes recently gave a talk on his technique to a Michigan audio club. There's a PowerPoint presentation of it available at '*http://www.gedlee.com/downloads/Optimal%20Bass%20Playback%20in%20Small%20Rooms.pptx*' (http://www.gedlee.com/downloads/Optimal%20Bass%20Playback%20in%20Small%20Rooms.pptx). There's really two versions of the Geddes technique. The first is as described in the link to the blog of DS-21, and the second is as described in the slide show, but the latter technique is unfortunately only available to people who buy subs from him. There's also a video of this presentation '*_here_*' (http://www.ustream.tv/recorded/28637776/highlight/319149). It's almost an hour long though. If you do watch it, be aware that they're having a whole lot of technical problems with the video equipment at the beginning of the video, but if you fast-forward to about 6:15, you'll miss most of the problems but not any content. To me, the most interesting part begins at about 31:00 into the video, where he starts talking about what his software does. This software ends up making some crazy-looking filters for the subs. You can see these in slide number 28 of the slide show if you don't watch the video. These filters can be created using a Behringer DCX2496 or miniDSP (used only for the subs, not the mains). Being a software EE, it got me curious as to how such software might be implemented. I'm going to have a crack at it sometime this year. ------------------------------------------------------------------------ andy_c's Profile: http://forums.slimdevices.com/member.php?userid=3128 View this thread: http://forums.slimdevices.com/showthread.php?t=98057 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
