I'm planning on building a vented sub using the Tempest Driver and probably the AVA 250 Amp. I've NEVER done anything like this before, so I am not equipped to do my own enclosure design. I have seen the Adire Alignment, and a few others, but was just curious to see any pre-designed options I might be missing. Can't go IB or Tube, so I'm just interested in alternative box designs that others may have come across. Strictly HT use (at least 95%). Thanks.
