ported + double bass = sloppy. Delay ftl.

Not all the time. If your enclosure is too large for the driver, or if you're using a driver not really suited for ported enclosures, then yes, it will sound sloppy. Group delay plays a large part in double bass sounding sloppy. Your front stage also plays a huge role in how double bass sounds. Most drum hits play more than just low frequencies and if your front stage sucks, so will the double bass.

Mabie, fill will damp the response and help the sub to stop moving faster (think of shocks on a car's suspension) but it will also reduce the peak spl slightly (no such thing as a free lunch) so I would try it with fill and without, and use what sounds best to you.

[edit] kick drums contain a signifigant amount of higher frequency information, so correct intergration of the sub into the front stage is essential to get the sound right.

if you go ported just make sure it is done properly. a correctly tuned and sized enclosure will do great. also the pg rsd subs are very good when it come's to sq. not to mention they can also get loud. but for your double kick well i dont think any of us can tell you what you want. do you want a solid amount of thump or sq with a little extra thump. i know you want your double kick but in order for us to know what exactly you want out of the sub we need more details. do you listen to rock only or do you have a mix of listening preferance.

i think he means double bass hits, like real drum bass. like i said i think. maybe he could clarify.

repeated bass drum hits //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Those double bass pedals that drummers have. Those really fast bass kicks. I think a 12" sub would tend to want a box around 1.5 cubic feet normally, am I right? About 1-1.75... and a single 12 in a sealed box should do well on tight bass hits.

yeah they usually do

indeed

so sealed is the way

yep

yeah the peak is reduced alot so your lows around 40-50 hz will sound deep and cleaner in my experience with that stuff.

The easiest way to get snappy, quick punchy bass would be to build a sealed enclosure. There's much less to go wrong in a sealed box, and they almost always sound good as long as you do OK on construction. Ported is MUCH more picky on build quality and dimensions.

I would recommend polyfill, maybe not packed in, but a little will help. Make sure you get a good seal though. When you push the cone down it should pop right back. If it comes back slowly, you have an air leak.

All in all double bass shouldn't prove too difficult to reproduce.

also is one of the boxes you listed already biult
