Over the past four years, I've read 1000's of posts on cab/speaker parameters and how to build a cab/speaker combination optimized to obtain better mid dispersion, maximize power/wattage and a wide/low frequency range. I've also read many other post on which speakers to use in replacing one or all in a cab. With BFM, Duke LeJeune and greenboy posting in many of the threads I've read, they have provided information and guidance to everyone who follows their posts/threads. Comb filtering, vertical stacking Xmax and many other terms have become standard on TB. My hat's off to them and all the other cab/speaker pros who spend their time giving us the "good stuff". What caught my interest recently was a recent DIY cab thread by JohnK_10. Based on his building experiences and testing he observed and concluded: And greenboy of fEARful cabs observed: Based on the above, my conclusion is that with today's speakers being able to handle more heat and move farther before breakup than ever before, by building a compromised cabinet and using less than the maximum power, it is more likely that the DIYer can achieve his/her tone/volume goals than there was in the past. Or if you happen upon an empty 80's bass cab in good shape and you are replacing all the speakers, lining it, bracing it, optimizing the port size as much as possible for the cab and using a couple of "overkill" Eminence speakers, you'll run out of cab before you run out of speaker. And, you'll probably have a great cab for rehearsal if you don't want to haul it or if you're on a budget, you'll end with a fine, giggable cab, especially if you're using an older head with 200 or 300 watts. It seems that the old saying "if it sounds good, it is good" applies here. Any thoughts?
