[QUOTE="Nick Hickman, post: 51884, member: 556"] Re: Single 18" LF Box vs Double Hi Uwe, Yep. With all things acoustic, it's a good idea to view the world in terms of wavelength. Something that's a major obstacle at 20kHz, for example, can be invisible to 20Hz. And what's "close" at 20Hz is miles away at 20kHz. One corollary of this is that the efficiency gain for a particular pair of sources is greatest at low frequency and reduces as frequency increases. As frequency gets higher, not only does the gain decrease, but changing directivity patterns develop. FWIW, some time ago I tried putting numbers to this using a simple model of point sources intended to represent varying sizes of a grid of 18" drivers. (It's an inadequate model but, I think, instructive nonetheless.) I wrote: Nick [/QUOTE]
