Has anyone heard these yet? I've got a credit at MF and since I don't have any good computer speakers left after my latest purge and I do not like headphones, thought these might be interesting.
That's a serious "computer" speaker

From everything I've seen, Behringer makes some excellent value monitors.
That said, looking at the lineup, I might be tempted to go with the B3030A.
The rated low frequency extension (no tolerance like 3db listed) is the same for both. The 8" (3031) will go louder, but near field, for you computer, this might be moot. The only troubling thing I see is the rather high 3.3k XO frequency to protect the ribbon tweeter. That's fairly high to run any 8" driver.
Luckily, they are widely available at Pro stores, so if you could go give a listen, that would be best. Pay particular attention to the midrange.
Personally, I might opt for the 3030 and save a few $$(500 vs 300ish).
But it's you, you have to please

cheers,
