Hello everyone. After having read a lot of sites about DIY sonosubs, I am very much considering building one for myself, but my design idea isn't quite so basic as the water heater look and leaves me with several questions which I hope will be unique so I'll get right to the details of my idea. I have never built a sub myself, but I have a general grasp of the concepts, but I don't want to be "spoon-feed" if I can help it. This is what I had in mind for components. The trusty Tempest that I have read many good things about along with a 250 watt plate amp probably from parts express w/ remote. Simple enough.. Now to where my design differs from all the others.. I don't really care about how big it is.. My opinion is: the bigger, the better. Since I am a n00b, I am lost at what produces the problem of "standing waves" Many of the other DIY sonosubs I have seen don't get much taller than 4 feet.. I am thinking for mine, more around 6' - 7' overall height, BUT, not just a straight tube like all I have seen so far. I just don't like the "water heater in a sock" look and would like to be a little more artistic and unique with my monster. So, here is what I was thinking for my enclosure, if it is sonicly feasible. 24" tube aprox 3.5' in length 18" tube aprox 2.5' in length 24" on botton capped and routed to accept the 18" tube on top of it. Driver downfiring out of the 24" with the port (6"?) exiting out of the 18" tube on top. You may ask why such a strange enclosure desigh and here it is.. I was thinking of how to make a stupid tube look cool.. what I came up with was to make it look like a 3-stage rocket like the old apollo rocket missions.. so, having the bottom 2 "stages" be the enclosure, for legs, it would have a rockets "stablizing fins" with a slightly larger MDF base for the "launch pad" along with whatever I can come up with for the crew capsule positioned above the port with of course an airflow gap.. So, is there such a thing as too much enclosure space?
