SPL vs IMP

DDQ 4.5-2 splvsimp
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!

DDQ5-2 vs 5-inch TRADITIONAL WOOFER

DDQ5-2 VS 5-INCH

Notice: DDQ5-2'curve was tinted red & 5-inch woofer's curve was tinted blue, the two bottom curves tinted with light colors were their impedance comparision. They have similar F0 but totally different bass performance below 100Hz! (click pic for large view)

So DDQ5-2 could give a much better bass quality! DDQ5-2 is very suitalbe for small bookself cabinet.(click for large view)
