No experience with the 410HLF, but I do own a 215BH with original speakers. The Sunn is capable of a hefty bit of volume, but I might second the sentiment that (at least speaking for the original speakers) they might not be your most efficient option. On paper, your head is capable of a higher output than what the Sunn drivers are rated at, but like any other amp/cab pairing - it's best to use your own ears and the numbers are flexible. The Sunn will give you quite a bit of grunt before crapping out, so you need to listen if you're giving it too much if you care about those speakers. That said, I find the Sunn cab to very low-mid punchy, with smooth highs and it's definitely the meatiest cab I own (in terms of tone and weight -the cab is HEAVY) and that includes an Orange OBC410 and the newer Ampeg 212AV. It also sounds incredible with any head I put into it. With the Acoustic/Sunn combo, you'd definitely be rocking some rad vintage gear. Heavy, rad, vintage gear.
All bets are off if the speakers have been replaced, or you are planning on replacing them. In that case, it can be anything you want.
Also, food for thought, (and Jimmy can correct me if I'm wrong) - I seem to recall seeing a fair number of posts on the HLF that mention a different tuning to that cab that comment about it being BOOMY and a little unwieldy in the low end(?) I might have that incorrect(?)
