first, yeah.... I agree... but you hav...hey JS....<br /><br />first, yeah.... I agree... but you have to step back and look at the application....<br /><br /> years ago we established that a phase plug larger than this one sounded and measured better in the midrange on the big LC horns.... so we know the reflections must not be as much of an issue as they appeaar....<br /><br />second, we cannot drill out that pole piece... you should see the magnetic models of it.... so this alignment, while not perfect, is much better than being three feet away on the outside of the horn.... <br /><br />third, because it is to mate up to the lowther front horns, we need something with better than 105dB... this is the smallest great sounding tweet we have found... <br /><br />I hope this helps clear up some of the reasoning.... <br /><br />Peace,<br />MeJeffrey W.

Also, typically you need the tweeter behind the lower frequency driver to get good group delay (time alignment). Looks cool though.Unknownhttps://www.blogger.com/profile/05837045852096004930noreply@blogger.com
