I'm a relatively recent convert to OB speakers. Mine use a 5" field coil drivers w coax whizzer and a pair of 12" subs. Love 'em.

Open baffle has rear output which allows the speaker to take advantage of the ear/brain system's abilities to find the source of the sound- in effect, the reflected sound improves the soundstage.
They can make bass too if properly set up. However it does seem that you get the best results if the output impedance of the amplifier is higher rather than lower! A tube amp that does not use negative feedback is recommended- this will put the output impedance in the right range and it will be easier for the speaker to make bass.

I recently purchased a pair of open baffle speakers (Triart Audio) because I was impressed with the open soundstage and highs. But I should have auditioned them with rock music because the impact of drums is just not there. The bass instrument in Jazz music is too light as well, although female voices are excellent. The lack of bass is despite having a pair of 15 inch woofers in each cabinet! Overall, I'd say they are great for classical and jazz music, but not rock.
