I thought it might be fun to see what differences we have between the original Infinity IRSV woofers in Music Room II, vs. the new woofers we replaced them with. As I mentioned in this post, the technical differences between the woofers are rather a lot, and sound quality is even more dramatic. The drivers we went with are off-the-shelf beasts from Dayton Wright. We did have to make some adjustments and 3D print parts to make each woofer fit but, in the end, these are what we went with. Here, by popular demand, are photos of the before and after drivers.
