My turn to DIY.
So, exept from some DIY car subs in earlier years, i have used SVS (and lately PSA) as subs in my HT.
Been thinking about going DIY for HT subs too, and when i found this thread about coolrda and his most exellent sealed dual opposed 18 SI sonosubs, i got really temted:

The reason this got me exited was partly because i heard how deep my PSA S3000i dual opposed sealed 15"s worked, and partly because we use sonoco tubes at my workplace, so i have free acess to tubes.
That suddenly makes sonosubs easy attainable.
So the tubes have these maximum measurements:
ID x thickness x length
597 x 10 x 1500 mm = 420 liter
23.5 x 0.39 x 59 inch = 14.93 ft3
Also there is pre-cut lengths of 1230mm/48 inch.
According to coolrda's recept, they are 9.2 ft3 in net volume, but since his tubes were 30"D x 24", and mine are 23.5"D, i need to make them longer, like 0.99meter /39 inch to get 9.2 ft3 net volume.
I plan on having them in the front corners, where the subs i have today is, so i have room for more tube length, if needed.
And of course i plan to use the same drivers, the Stereo Integrity HT18D2 v2, 2 per cab.

Basically a copy of coolrda's Fatmans, just adjusted for length.
Couple of questions:
1. Would a push-pull design be any better?
2. Would a ported design be better?
3. Is there a better driver in that pricerange?
4. Is there a better cab volume?
PS: already ordered the drivers, but will take a while to Norway.
Edit: as the drivers is ordered, forget question 3
