Would it be worth it to create an Adire Tempest Passive Radiator setup using 2x Adire's PR15's over just a ported design instead?
I built the ported EBS enclosure for the tempest:

It sounds great, and goes quite low. I was messing around with the tone generator, and there was quite a bit of output as low as 10hz, and it was shaking the glasses in my kitchen cabinets when the gain on my parts express 250w plate amp was turned all the way up. (sub was in the adjacent living room)
I was going to build the PR version, but didn't want to drop the extra cash on the components. I have read some peoples reviews and opinions on the PR version, and they seem to say that it is quite a bit better, but a whole lot more money in drivers. If you don't mind spending the cash on the PRs, then I would go for it. When playing at loud volumes (too loud for my apartment), I get some port noise from the two 4" ports. They push A LOT of air at loud volumes with this subwoofer enclosure. I was amazed.
The comments about the PR setup was that it had more defined bass, and no port noise. It was like combining the a sealed box with almost the extension of a ported box supposedly. I haven't heard one.
Check out the home theater forum for some opinions on the enclosures. I forget when I read about them when I was doing my research a couple of months ago.
Nevertheless, I think that you would be satisified with the ported EBS tempest if you want to save money. The bass extension is amazingly low, and with even 50w of power, it is enough for average use. 250w of power is simply insane with this sub. I put 350w into it in my car (honda civic hatchback, barely fit), firing back against the the glass in the rear of my car. (pic of car at: http://brian.darg.net/misc/aaa ) I could not stay in the car with the volume turned up loud. I opened the drivers window, and used my remote control to turn up the volume of the amp, and it shook every body panel of the car, and when one of my friends was listening to it in the car later, he claimed to have hearing problems for the next couple of days. I put some good ear plugs in my ears and cranked it, and it was quite an interesting feeling having a good deal of bass in my car over my small 10" infinity sub in a sealed box. I am afraid I would get brain damage and my car would fall apart if I left the sub playing loud in the car for an extended period of time.
If you can deal with the size, build the EBS enclosure with whatever version you build (size = 2'x2'x4' including the 4" feet)
I guess you have looked over the Tempest reference designs at:

Here are some quick links that I dug up for info:
PR information for enclosures
http://www.diysubwoofers.org/prd/
Subwoofer DIY page forum (plenty of info on PR systems, use the search tool)
http://www.diysubwoofers.org/talkshop/
Home theater forum.. search here for some info

One more thing that I read before was that the dual PR enclosure looks damn cool with the PRs moving.
