SPL vs IMP
Notice：This is a near-field curve(10cm with a magnitude offset post-processing). The measurement environment is a big sealed MDF box(volume is about 400L, 60cm*122cm*55cm, very similar to a infinite baffle). This is an authentic raw data without any smooth processing! Please give extra attention to the performance below 100Hz!
