I was thinking earlier while looking for replacement 10's for my cabinet... WHAT ABOUT A HORN LOADED 2x10? The speaker i have in mind, is not very efficient per say, but it has 11.1 mm of Xmax. If this speaker was horn loaded, what is to say that it cant become VERY efficient and make a ton of noise? http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=290-574 However, im having problems locating any kind of designs for horn loaded enclosures. Does anybody have any resouces for: Horn Loaded Designs? Theorys? Design Software?
