Ok, I'm contemplating doing a radial design with only one fullrange (commercially available) driver (currently FE126 as I want to floor-load it).
So, the first problem seems to be how to do the reflector. Where to get it or alternatively how to DIY easily?
- A simple cone seems not to be the preferred shape, but could it work? And how steep can/must it be?
- A ball would reflect most of the highest frequencies right back at the driver, so even though some use it, it seems too much of a compromise, especially when talking fullrange one driver.
- An exponential spike (mount Fuji shape) like the Duevels seems ideal, but very hard to DIY or find as a part.
- A horizontally curved panel like the Paragons (http://www.audioheritage.org/html/people/wolf/paragon.htm) seems to be the easiest way to go, but how long does it have to be to be effective? And also, it needs to be mounted horizontally so that means a wide speaker, something I would like to avoid as it limits the placing options.
- One alternative I've been thinking about is bending an oval (to compensate for anisotropy) piece of plexiglass lengwise in an obtuse angle.
Then put it at a 45 degree angle above an upwards firing driver to get a good 180 spread, instead of the 360 spread, where much of the sound goes to waist in curtains, walls and furniture.
Anyone tried something like this, or have any interesting links to simple DIY radial speaker projects?
