[QUOTE="Savant, post: 189731, member: 546108"] K.. using win isd.. on the specs for a Pioneer Premier 1241dvc.. 3 cubes 26.9 Hz freq 1 port at 6" x 30.56" Max port velocity of 15.5 m/s at 25 Hz (but I have a sub-sonic filter on set at 20 and the design is set for 30 Hz to be at 0dB, 25 Hz is at -3.5 dB).. It's a 500 rms sub, but I have the wattage set to 350 to stay in the mechanical excursion (but since 3 cubes is a LOT bigger than I wanted, but that's the only way I can keep the port lengths reasonable (not sure I can find a 6" flexable tube either *sigh*) and still be near 30 Hz as the 'base' of the top of the response curve... Does that look ok? Anyone know where I can get 6" flexable tubing? Is PVC flexable under heat (I thought it was, but now I don't recall .. been years since I've messed with PVC)... TIA [/QUOTE]
