Well i decided to open this thing up and see how well it is made, first thing i noticed is the cabinet is made of something a little denser then OSB and it is about 1/2 thick at the back and gradually tapers to a 1/4 inch as it goes to the front. the inside of the cabinet is damped with what appears to be polyfil, and there is an actual crossover board in it not just a capacitor (as i have seen with many cheap speakers.) the wires in the cabinet are nice 16 ga wires with aluminum locking connectors (best way i can describe them) the cabinet has several bracings running along the sides and across the cabinet, from what i could see there were about 8-10 bracings in all. each of them were approx. 1/4 inch thick. running some test tones through it i could tell the response goes down to -3dB at 40hz, and drops about 6dB at 35. it will play 20hz at -10dB. the port extends about halfway down the cabinet. the back of the mid-range is sealed and the back of the tweeter is also sealed. i noticed the x-over point for the midrange is about 1khz, it's not a steep x-over because all the way up to 2khz i could faintly detect sound from the actual woofer. the tweeter starts crossing over at about 8khz.
