After lots of research and question in this forum I finally decided what I want. I will go with the Adire Tempest and with the Parts Express #300-794 (250 watts amplifier). I will use one of the recomended alignments, either the EBS design (340L tuned to 15.8) or the SBB4 (194L tuned to 18.8). My first question is regarding the port. Should I ask Kyle from Acoustics Visions for an specific one? My second question is regarding Xmax, if Im using Unibox right, both alignments results in overexcursion of the driver, even with "only" 250 watts. Perhaps Im doing something wrong. My last question is regarding the stuffing, are there pictures of the polyfill needed? I still don't know what is like or how should I buy it in here (Mexico).
