On my Mac desktop at the outpost I added some Audioengines 5+ speakers for a make-do HT system. 27" is pretty small, even for the apartment, but for the little time I spend watching videos it works. The Audioengines sound pretty good, but I've always thought them to be a bit boomy in the upper bass. So last time I was at home I brought the OmniMicII back with me.
Sure enough, centered smack dab at 120Hz there's a huge spike in the frequency response. Nearly 13db. A little hunting around on the App Store got me Boom, a parametric equalizer program for the Mac. $6.99.
Boom works like a champ, and I smoothed out the Audioengines' frequency response to a +/- 3db tolerance with 1/6th octave smoothing. Not quite as smooth as the Salon2 system at the big house, but overall the Mac and Audioengines don't sound bad at all now. The 5+s reach right down to 40Hz, after which they fall off like a rock, but 40Hz is pretty good for such small speakers just sitting on a desk.
Boom is a bargain at $7. If you have a Mac system, highly recommended.
