The Audiokinesis 112 has your name all over it

34 pounds, nice low end extension, low SPL but 4ohms so that a relatively small head can result in 'almost' 212 volume.
If you want small, light and low, and moderately loud, this is the king of the hill, and I've played about everything. It isn't a 'sizzle machine' or anything like that... very smooth and organic, with lots of low mid/upper bass meat/punch, nice true low end, and a very nice, natural, organic top end.
I've rarely been as impressed with a cab in my almost 40 years of 'gearheadedness'.
Edit: If you need a bit more volume and want a bit brighter voicing, the 55 pound Bergantino AE212 is magnicifent.
