Danny, that train (desktop speakers) has left the station. Not being self-powered plus having thin mid-bass/no-bass (appreciate the honest reporting) isn't gonna cut it against in the market place.
Some examples of 'serious' self-powered speakers that are currently available commercially include:
For single driver design: Serene Audio, bamboo/leather, compact, three different shapes offered, active by default with DSP, F3 = 70 Hz, $500/pair
For cheaper 2-way designs: Audioengine A2 and PSB Alpha PS1 both are smaller (guessing), powered designs, F3 = 80 Hz, Stereophile recommended, under $300/pair
For more expensive 2-way designs: Adam F5 and Paradigm A2, active designs, F3 = 55 Hz, under $600/pair.
It'd be hard to compete with the technical advantages of powered/active designs (as you're already finding with lack of bass) and lack of desktop clutter.
