thanks a lot for your answers
IronLion: my question was for those who had already opened, for any reasons, their speakers, i never tought that soembody could have opened its own just to help me

Red Dragon: thanks for your suggestion, I've already written an e-mail to ref3a, attaching some photos and a as precise as possible description, but their reply has been too much generic, something like: your speakers are what should be....given your photos
Tha's why I've asked in this forum. My bigger doubts are on the wire uused for the tw (I thought it was vdh scs as for the woofer, while in fact it's vdh the skyline) and on those 2 very very little resistors, or inductance, or I don't know what elese they could be, but Tash at ref3a did not made me aware of any quetion about them
Thans again
