Tempest Questions

[jbandpc]

For those of you who have built a Tempest:

Did you guys coutersink the driver? If so, how much? Is the cardboard-type stuff around the edge for internal mounting only? Can I rip it off if I mount externally, so I don't have to countersink as deep?

The Technical Data sheet for the Tempest from Adireaudio.com has a section called "Applications" in which it list performance for a sealed box size of 4 cubic feet (net) with 48 ounces of polyfill. Elsewhere on their site, in the Reference Designs page, the "Mid-Q" design is 4.6 cubic feet, but calls for only 32 ounces of polyfill. Of course, after factoring in the displacement of the driver and braces, it's probably around 4 cubic feet net too.
Why does the "Technical Data" example call for 50% more polyfill than the "Reference Design" example for the same size box?

Getting any info about the Tempest in this forum is like pulling teeth. I've been trying to get people to give me their opinions comparing the Tempest to the Dayton DVC 15, and so far one person has given his opinion. I don't know why this forum is so dead and nobody seems interested in talking about these subs.

Why am I not suprised that you and I are the only two who have posted here?

I don't know when jbandpc and I will ever have time to read all the replies in this topic. There's just so many it's overwelming! I will have my Tempest sub project done in a coulpe weeks and will post a full review. I hope there will be room in here for my post!

why you didn't try other forums. I gave you quite a few links and you didnt even try. it's not their fault that they didn't build the Tempest sub and can't give you answers. Not everyone did or is trying to do what you're trying to do. go to diysubwoofers.org they have a great forum and those guys tried pretty much every subwoofer driver out there.

I did try the other forums and there isn't much in there either. It seems strange that there's more info available in the car audio forums about the Tempest than there is in home audio forums.

In case anyone's reading, I started my Tempest project yesterday. I got all the peices cut, including the internal braces, and the driver cutout. I'll be finishing the legs today. The Tempest is scheduled to arrive Monday, according UPS. Then I can drill the mounting holes and install the "T" nuts. The biggest trick is going to be gluing all 4 sides together. With all the corners cut at 45 deg angles, all 4 sides will have to be put together at the same timeOnce assembled, then comes the staining, sealing, and final coat. I should have it done in a week or so. I'll stay posted, in case anyone's reading.
