I am new to this forum but not new to audio. My problem is I moved my door speakers (6.5" pioneers) from their 48mm spacers (sitting on the door card) to flush with doorcard protruding into the door. I had to do this as me and my wife kept injuring ourselves on these huge spacers protruding into the footwells. My sound was pretty decent before I moved them into the door but now there is a lot less bass.
Can I make up some 6" dia pvc tubes and fit them around the speaker inside the door to sumulate the 48mm spacer or am I waisting my time?
Any suggestions are welcome
