[QUOTE="audioholic, post: 5874649, member: 549629"] I agree the environment plays a bigger role on posdsible scores than does the equipment itself, when comparing reasonably comparable equipment of course. If the mic is on the opposite side as the open door, my guess would be the main air flow through the vehicle reflects off the passenger side, across the seats, and through the door. This would yield an area of high pressure on the pass side, where its reflected, and thus slightly compressed. This is a perfect example of why cabin space isn't the end-all answer to SPL scores, but I did not mean to imply it was earlier in the thread either. But thats obviously just a guess why your truck acts like it does, and you've probably already considered it. I dont remember if you have a TL, or have access to one regularly, but if you do it might be a good idea to try and map out the pressure zones in the cabin to locate the air flow path. *shrug* On the blazers... just seems odd with an otherwise exactly the same interior from the b-pillar forward, and with a wall just behind the front seats, making both interiors for all intents and purposes the [I]same[/I]... why would a 4-door be arbitrarily louder. With the wall located behind the rear seat, sure, things will be different. Air velocity inside the cabin would change with a door or window open due to different path lengths, but a wall behind the front seat showing differences just doesn't make sense to me. edit: In thinking about it, I guess transfer function on the 4-door would still be different even with the walls behind each truck's front seat. But I dont see any other difference between the two setups otherwise. [/QUOTE]
