I would just like to add the Audiosystem F2-300 to this list. $599 rrp, 780 wrms into 1 ohm Class A/B, made in Italy and 3 year warranty. Plus, buy the two together, ie woofer and amp and you can get a system discount.
Go the hard sell!!

I imagine the radiator would be similar to running a enclosure with a big port yeah? More bass but slower response?
Honestly, why is this "PORTED IS SLOWER THAN SEALED" crap still being spread around?
Do you know how many ultra-highend home speakers use ported alignments?
From a very recent US mag review:
"This driver sits squarely on the fence that divided drivers into better-in-sealed, or better-in-vented types. For our sealed-box system, we found between 30 and 50 litres gave us a solid low-end with a roll-off that nicely complemented the boost of the passenger cabin. We modeled it in sealed enclosure of 40 litres. Listening tests bore our findings, but we felt this driver was not giving us all it had, so we opened the vent in the enclosure and slid in the port to tune it to 33Hz. This made a magical difference. Whereas we found the 15” WOOFER tight and solid as a sealed system, the vented system was powerful and had a very satisfying weight at the bottom end of the scale. Technically slightly exaggerated, this response was -3dB at 48Hz, but had more energy just above the roll-off, and was just fabulous to listen to. A couple of musicians visiting the lab while this was going on had the opportunity to listen to the 15” WOOFER in sealed and vented modes, and the verdict was unanimous in favour of the vented set-up.
Some more computer modeling suggested a larger vented system would deliver even more deep bass, so we moved the driver into our lab’s 60-litre enclosure, and again tuned it to 33Hz. In the lab, this gave impressive amounts of throbbing bass (with a -3dB point below 40Hz), clean as a whistle sound, and enough decibels to affect your eyesight. As always, this sub went even lower and louder in the car. With a 70Hz crossover, we listened to a wide selection of program material on this set-up, appreciating the sense of size and power that it gave, even to Mozart’s “Cello Concerto K622,” a bizarre choice of sub test material to be sure. The deep bass was prolific and well controlled, and went deep enough to make most bass lines sound menacing.
We listened for deep bass extension, dynamics, smoothness, freedom from resonance, and lack of distortion."

is that a fair comparason? you're not only comparing 2 different sub sizes, but also 2 very different subs.
