I am still in the planning stages of building my first sub so I am not an expert on this stuff. But looking at the new Adire Maelstorm I would think the tempest would still be a better driver. Am I missing something in the numbers? http://www.adireaudio.com/cd/maelstrom.htm Using the WinISD program for some modeling. I do not ever see a difference between building say a box with 1 driver - vs- 2 drivers or more etc. What is the advantage of more drivers. Or say building an enclosure with 1 driver, then having two of those enclosures stacked on top of each other like I have seen some people do? Also if you have a plate amp and a dual voice coil driver how to you wire them together. Wire both voice coils together, both + to the + of them amp, and both - to the - of the amp? What would the ohms end up being on this? Thanks.
