I've fitted them for the acoustic quality, and can report no real difference. In the pics if there is no silicone / sealant then it's just because it hadn't been done yet . Every job needs to be sealed so you can't pee down the gap after too much ale I always fit the pan loose, squirt sealant / silicone between the pan and the wall, then fully tighten. As the sealant oozes out you clear it away with baby wipes / tissue and CT1 multi solve ( if you've used a non silicone like CT1 ) and then
