[QUOTE="lanties, post: 437922, member: 13832"] Here are some more measurements of the 26W8861T00 in the box. The measurements are: Red = Driver and Port near field measurements in box merged with no XO Black = Driver and Port near field measurements in box merged with 2nd order XO using a 5.2mH at 0.23Ohm coil and 88mfd Cap(s) All measurements done in Omnimic. Data merged in Speaker Workshop and exported to FRDs and again displayed in Omnimic. I am not sure how to interpret the results below. To me it looks that I am dipping correctly from +/-250 Hz but why is there such a huge bump at 800hz? [IMG]http://i186.photobucket.com/albums/x125/datatex/Revelation_Two_Monitor_MkII/XO1_Port_And_Cone_merged.jpg[/IMG] This is an impedance measurement of the driver in the box without any XO.
