Having completed my Tempest based ported sub I'm very pleased with how it turned out and wanted to share a picture and say thanks for all the help along the way. I used the Creative sound 250 RF plate amp with separate remote and the Tempest in a 175 ltr box using a Dan Wiggins plan. Being my first project I was a little worried that it would sound like it was DIY but the thing is excellent, depth charges on U571 shook my sofa from 18' away through a concrete floor and it integrates well with my Mission/ NAD system. I don't have an SPL meter and as I'm very pleased as is probably won't bother with one.
