I am currently considering these two heads. I have a separate EQ, so the EQ difference is not an issue, and I have an adequate amp so the RMS power output difference is not an issue either. I do have to turn down the gain on the amp in order to lower the amount of noise, therefore the higher preamp voltage on the pioneer model is appealing. However, I am concerned over the short range of its RMS Power Bandwidth. Yet, I can't find much information on what this figure really means.
What does RMS Power Bandwidth really mean, and what are the consequences of an RMS Power Bandwidth of only 50-15khz? It seems like that feature is going to be the deciding factor between these two heads.
Other than that, the only other difference is the cd signal to noise ratio, but my understanding is that with road and engine noise on a car with no noise shielding, the difference between 94db and 105db is negligible (correct me if I'm wrong on that).
If anyone has any other views on which to get, please share them as well. But my main concern is this RMS Power Bandwidth figure.
