It is not a Butterworth box and it is not trying to be. Qtc 0.707 is not reachable on this driver at any volume: a sealed system Q can never fall below the driver's own Qts, and Image Dynamics publishes 0.95 for the D2 coil and 1.02 for the D4. What the higher Q buys is a rise around 49 Hz and a half-power point of 33.8 to 34.2 Hz anechoic, which is lower than a flatter alignment of the same size would reach. In a vehicle, cabin gain works on everything below that.\u003c\/p\u003e\n\u003ch3\u003eAlignment Numbers\u003c\/h3\u003e\n\u003cp\u003eD2 Qtc 1.559 · D4 Qtc 1.674 · fc 49.2 Hz · F3 33.8 to 34.2 Hz anechoic\u003c\/p\u003e\n\u003ch3\u003eMounting Geometry\u003c\/h3\u003e\n\u003cp\u003eVertical baffle CNC cut to 14.764 in.
