Yep.

OK, made measurements today. The SPL Meter was wedged between the driver seat and headrest, the primary listening position. I took measurements for just the subwoofer and then fullrange. It is important to keep in mind that for both measurements, the EQ (Bass and Treble) built into the factory headunit were basically bypassed since the Line Out from the computer was connected into the Cleansweep. Any EQing was done from the Cleansweep... come to think of it, I probably should have made a few measurements with Cleansweep EQ Bypassed. But then again, maybe the Cleansweep EQ is automatically Bypassed when the Auxilary input is being used. Here are the results:

SUB:


Full Range:


The SUB in car response was not too bad, especially since there are no treatments (such as dynamat) or Sub EQing of any kind on it. There are a couple of +9dB peaks at about 30 and 47 Hz but everything else is pretty tame.

Full range response is a little more out of control. Mid-range drops off a bit from the bass and treble; if you consider the response at a target of 80dB, then midrange (400Hz-3500Hz) is down about 10dB. Upper treble drops off after about 10kHz but the SPL meter is not nearly as accurate in that range either. If the stock headunit EQ was not bypassed, then it would have been pretty simple to bring down the bass-midbass and higher midrange-treble ranges down about 10dB to flatten the response a bit. During normal listening, however, I can use the stock EQ.
