Bass Blockers act as high-pass crossovers to guard against distortion, especially when you turn up the volume. Remember, the smaller the speaker, the more difficulty it has reproducing low notes at high volume. Eliminating low frequencies from a smaller coaxial speaker means you'll get cleaner, louder performance. And, since the bass coming from your back speakers (or subs) is omnidirectional, you'll never know the bass blockers are there! It would be better to get a speaker that can handle the RMS that you are wanting, as opposed to trying to 'overclock' a smaller speaker.
