I have a collins diaphragm type, even drilled the holes around the outside out to max so to make louder, love them myself, nice and quiet when driving normally.
After being nagged by my lad(13) for a bit of chatter, I unplugged etc, and so had chatter, the difference in pick up was immense, was really like night and day, felt like I'd knocked a plug lead off, so run dv.
