So about 5 years ago while I was working at a Storage facility, I came across a DIY Sub with an NHT1259 in a 3 chamber box, with 3 ports outside, and 2 internal. My Pro sound knowledge led me to believe this is a 6th or 8th order bandpass. When i ran a plethora of audio through I found to be quite flat as a sub, doesn't really favor any one frequency. Aren't 6th/8th order boxes supposed to favor like one narrow band at high SPL's? Overall this box kicks, and all my audio engineer buddies borrow it from time to time sayings its one of the flatest subs they've heard Either way this box baffles me and was hoping for some insight.. Yes I'm new here....
