Sorry for the long post... So I was contemplating building a pair of floor-standing speakers and I looked at quite a few different designs. I considered going with the classic sealed, square box, but it seems that lately there's been a general movement towards ovular shaped towers in high-end speakers. I realize that this helps counteract standing waves and looks aesthetically pleasing. However, from a DIY standpoint, it may prove difficult to build such an enclosure. What I was thinking instead was to use a hole saw and make a stack of MDF to create a sealed cylindrical design. If it would make sense I could also make any portion of the cylinder larger by cutting a larger hole in that cross-section. I am new to building speaker enclosures so I don't know if this design is worth pursuing, however I would assume because it is sealed (unless it would make sense to port) I need only worry about the volume inside (much like a traditional box design) when choosing drivers. I did some research and I came across a similar design by Jim Rogers back in the 1970's (attached ) but I don't know how relevant that would be. Are there any drawbacks to this design? Should I worry about any particular details not involved with traditional box speakers? Thanks for any feedback.
