My stock Honda door speakers were replaced with four Alpine SPS-610's. I used to keep the bass at +3 (out of 6) and got plenty of low-end from the stock speakers (same size). Now, even with the bass cranked to the max (+6) I get almost no bass response, and the sound is very harsh to the ear!
I'm not using an amp or sub; just simply upgraded the speakers. Unfortunately, this has been a major downgrade in audio fidelity. I've read great reviews on these speakers, so I feel I'm missing something.
Do the SPS-601's have bass blockers built in? I cannot find anything to confirm this, but it definitely sounds like a high-pass filter is applied. What is the "Bennic" capacitor in the attached image? Is it a bass blocker?
I appreciate any insight.
