Okay, this is going to sound strange, but everyone at one point wonders how hard it would be to make a homemade speaker cabinet. I myself have made several 2-way 12" pa cabs, but my friend, also a bass player, wants to know the feasability of making an 810 cab. http://www.steelsound.com/product.cfm?ProductID=76 I found a driver online that goes from 55-5500hz, remarkably similar freq-resp. to the Ampeg SVT810E... it handles 100watts, so if I had 8 of them, it would handle the same wattage as the SVT810E. I know madison speakers are inexpensive. Does anyone have any prior or heartbreaking experience with Madison Speakers in general? I know this will probably get me laughed out of the forum, but do any of you have advice for someone who would try this? As of right now, My friend and I have alotted lumber for the internal baffles like the Ampegs, and could wire them similarly. Furthermore, instead of costing 1000 bucks, they could be made for about 600, minus our own labor...(free). Any thoughts? This is just an idea, we haven't started it yet.
