I'm thinking about buying one instead of the Tannoy iwSA 500 D. My only concern is that it might not have the kind of current output I like.

Doesn't matter, all that is handled by the surround sound processor these days and I'm not a big fan of subwoofers with two-channel systems, which is why I still can't get my head wrapped around what the HK 990 is for. I suspect it was probably designed with something like the JBL LS Series in mind .

So, this Parts Express amp/crossover has a 3 dB bump filter at 25 Hz (or you can use the EQ at ~25 Hz instead if you need more boost), the 1500 Array has a 4 dB bump filter at ~25 Hz and the BX63/BX63A has a 6 dB bump filter at ~25 Hz. Some people don't like any bump filters with their B380 or B460 (it is room dependent). My point is, this Parts Express offering has a bit more versatility. Some people/manufacturers use plate amps instead.
