[QUOTE="Peter Morris, post: 138208, member: 652"] Re: New DIY Mid High Hi Spenser, I actually did this trick with the outer horn (below). I spaced the cuts at increasing intervals so I could approximate the exponential curve I needed. Having said that its not that critical, the difference between a conical horn, an exponential horn, and an exponential horn made of conical sections is not that much. The other thing to note is that if you make a 60 degree version you will need to make it a little deeper. Also note the clearance between the compression driver and the 12" is very small. It fits between the spokes of the 12" frame - you must check this all fits. [/QUOTE]
