Martin Logans are sexy but have a narrow dispersion. Sound Labs are not as pretty, but will out perform the ML's. If you want bass, the bigger the better. I have not heard the Innersounds.
If space is an issue and you want some bottom end, consider some Gallo Reference speakers. The sweet spot is much larger given the 320 degree dispersion mylar tweeter. Bass comes from two Dynaudio 6.5" drivers weight damped to match the natural roll off of the tweeter. There is no crossover, and integration is quite good. Space Invader looks you either love or hate.
