[QUOTE="Per SÃ¸vik, post: 91082, member: 1285"] Re: Subs, what to do if you lack excursion? Thank you Art, sorry for being such a dim-witted idiot about this, and I'm not done yet. Gotcha, allthough I beg to differ from a general use perspective :)~:-)~:smile: This is the port from the plenum, the front port? So the rear chambers are just ported as if the fronts were firing into open air, no compensation for the resistance when calculating, have I got that right? Got it, but I think I'll go for simplicity of construction at this point. Me lazy you know :blush:. OK, I guess I can just measure the current through the speaker while doing a sweep? Thanks again for all your help, I've got an outdoor show in a week, maybe I'll have at least one cabinet converted by then. [/QUOTE]
