You nailed it. For those reading I'll expand on that a little bit. The driver used in the A7s-450 is a smaller box performer. In this case the larger driver used in the cabinet replacing the A7-450 is meant for absolutely massive vented enclosures. I do mean big. 10cF is a lot of space :) This particular driver is purpose built for massive vented boxes. Using a speaker that works in a small sealed box in a big vented box isn't really a bad thing. It just won't have a ton of mechanical power handling. Taking a big vented box speaker and going in reverse to a small sealed box really isn't going to go very well. As is the A7s-450 would see less performance from swapping with this big underhung driver now being used in the A7-450's replacements. Much like the A7-900 it wouldn't only degrade performance in those applications. Garrett,

It needs a incredibly large box. The A7-450 is only marginally smaller than a A7-900. With that said the upgrade could be made but this particular speaker would be incredibly under powered if we tried to use a single LT/1300 to power a pair. This brings the A7-450 platform closer in performance to a A7-900 but the 900 still wins. In this particular case using this speaker (even though it's bigger) in the A7-900 would actually result in lower performance. The speakers in there currently are a lot more efficient. Nick,
