I have listened to my DIY fostex FF125WK BR boxes for almost 3 months. I like them for their midrange. After 300 hours of listening I decided to measure again their SPL. When I made them initially they showed a baffle step response and for some reason it is not very prominent now. I am inviting your thoughts. The plots from Fostex website almost matches mine I believe. The plots of mine are 1/12 octave smoothed. I am thinking about a subwoofer to augment the lower end. I will appreciate the cross over frequency suggestions for this box with a sub.

Hi, you need to do two things, first say the conditions for the measurement (in room??) and second adjust the vertical scale.

Sorry John.It was measured in a room of about 500 sq Feet.Please see the new plots.

I guess there is still a 2-3 dB BAFFLE STEPPING. Should I go with calculated 640Hz for correcting it?
