That's no wonder. As i've written above the BOSE speaker have a 8 cm (around 3 inch) diameter and the HAES speaker do have 10 cm (around 4 inch) diameter. So for the BOSE system 10 cm mid speakers are a real upgrade in the mid bass range. With the HAES mid speakers there won't be that much difference until you put in real high end mid range speakers that can generate real low end for a 10 cm speaker. So for the BOSE system i would also recommend 10 cm (4 inch) aftermarket speakers.

I'll put the BOSE ones on eBay. In a 996 they will be OK.
