[QUOTE="Peter Morris, post: 138465, member: 652"] Re: New DIY Mid High [URL]https://www.youtube.com/watch?v=sWPXiQTVrAo[/URL] I thought this video may be of interest. David Gunness uses the same trick as the DIY to get the path length needed for the (ported) horn to get down to 100Hz. If you didn't need to make the box as small as I did, what David has done mounting the HF horn concentrically in the mouth of the LF horn is the way to go.
