These cabinets were originally designed as passive bipole speakers; when 2 sets of drivers are mounted opposite one another, whose frequencies are played IN PHASE with one another (unlike dipole enclosures which play out of phase) Going the floor standing route also freed up having to make a stand, or stands. So in the end, we chose a combination of sealed and ported chambers for optimum sound quality. Porting to the front also allowed us to locate the speaker against a wall. Additional bracing and acoustic foam was added to prevent the ports from having unwanted high frequency resonance, like that annoying echo we all dislike. The double baffle also helped with this. And with our 4 chamber setup, each partition doubled as braces - making the box extremely inert, and fully dampened. Each is driver crossed over on a Behringer DCX2496 active crossover, and the xover points change according to how I feel that day :D The listening room is well, less than perfect - but still a good space for playing demo trailers, movies and music. However, during testing, distinguished standing waves were noticed in 3 places throughout the area. These types of issues, comb filtering especially, are the greatest and most difficult problems small rooms encounter. Thus, it's very smart to have plans built around the specific geometry of a room. That's the only way to build a high end home audio cabinet, after all, rooms affect sound even more than speakers do! Stay tuned this week as we learn how to build custom DIY speaker grills with neodymium magnets! The grill will help keep her clean :D
