Re: Dual 18" Separate Chambers ??I recommend a LinearX VI Box:http://www.linearx.com/products/accessories/Vibox/VIBOX_1.htmAnd mind the details here:http://www.soundforums.net/live/threads/2486-Loudspeaker-to-Line-Level-PadThis is a totally fine way to test what is going on, too. You can use the amplifier gain and known crest factor of your signal to calculate the input voltages close enough for this kind of characterization. You can also use Don Keele's 30-80Hz "thump" tone to pretty easily figure out when things fall apart for a given vented box. Steadily increase the level and all sorts of "noises" will appear. I'll usually stick earplugs in and listen right on the enclosure for gak with his stimuli once the levels get high enough. Or just hire me to design you something that will work proper from the outset ~:-D~:grin:
