Probably not, any synth can do it, but noone will be able to hear it, the so-called Brown note is allegedly between 5 and 9 Hz. The lowest we can hear is 20Hz. Most speakers don't even register that low frequencies, so it wouldn't work anyway.
Unless you use a specially modified speaker like they did in Mythbusters, they used twelve Meyer Sound 700-HP subwoofers, usually used for rock concerts. These subs are rated at 28Hz-150Hz, so they had to modify them to go down to 5-9Hz. The experimenters on the show tried a series of frequencies as low as 5 Hz, attaining a level of 120 decibels of sound pressure at 9 Hz and up to 153 dB at frequencies above 20 Hz, but the rumored physiological effects did not materialize.
The "brown note" is nothing more than an LFO "playing" between 5-9Hz. No speakers go that low, nor do you have the LFO as an audio source. On the show, they used a 110Hz sound to allow the viewers to hear anything at all through their TV speakers, but that was dubbed in afterwards.
