design cont....




Alright folks, I know we are like a week early, but, unless you want to do all the work yourself you must rely on and trust the work of the people that came before you. In this case, I do. We also can not thank the people enough for their tireless efforts of the past, for with out them none of this would be possible. There is a slight parts delay, you need to get as many of the parts correct the first time around so as to not lose ground later. This part happens to be the inductor which they say is a simple part but you have to understand how an inductor works in order get the right one and that's not so simple. The 24db/Oct device should be sufficient to fill a 20'x40' room and there are no forseeable problems associated with that. The commercial 48db/oct device is another story, it seems that the 48 numbers do not exist because of the degree of difficulty deriving the 24 numbers. So I shall attempt to extraplicate the 24 numbers and test that to hear if there is anything detectable to the human ear, or mabey a driver can pick up some differences at louder volumes.
Above is the enclosure that will be used for testing, the final design will be discussed later. I cut down some plywood and simply cut circles to match the drivers, well not so simply, you have to get the exact size hole the first time or try again. I burned through some lumber achieving that task. the location of the drivers is not exact but it is close and will be phase- arrayed in the end. So, when the time comes i'll get back to you with more.
