When dealing with drivers that move huge amounts of air, ports have to be huge. Is it OK to have U bends in ports or is that something you really want to stay away from?
Just trying to learn because I would like to try a reflex design with my Tumult just to hear it. If I really like it I'd probably try a 24" cube with PR's. It's just that's a lot of cash to shell out to find out you don't like the sound.
