The density & general construction of these baffles is good, but I found them too deep for my installation. Rather than send them back I just removed about a inch from the middle and glued them back together. Thereon the installation was relatively easy.

Work well. muffles the slight rattle when the speakers are in a door panel or kick panel.

Good idea for small speakers in doors. Installed these with a pair of kicker 4" coaxils. The difference these things make for sound of the speaker is night and day.
