Your problem drumbe is not your speakers, its your room. In a room 12x12 the first mode is at 47Hz (speed of sound 1130 ft/s divided by two times 12 = 47), second mode is 94Hz and so on. 47 and especially 94 are right in the area of the bass hump designed into most speakers regardless of design. Even worse since your room is 12x12 then you have the same modes both directions- double the trouble. (Please don't tell me the ceiling is around 12 feet too..... !)
The good news is there is a solution: bass traps. The bad news is figuring out exactly what to do calls for a little math and creative thinking. To be effective the trap dimensions and placement are determined by the frequency and room. Bass traps go in corners where walls meet, or walls meet ceiling, or both, and need to be bigger (thicker) to get lower in frequency. Beyond that you just need to figure it out for yourself. Not that hard but it does take a bit of like I said math and creativity. Oh, and a browser!
Or you can keep throwing money and speakers at a problem that has nothing to do with either. Bass traps are mostly fiberblass or foam which is dirt cheap compared to speakers. DIY! Otherwise if you stick with trying different speakers all you're really doing is trying to find one that's lean or even has a suck-out at those problematic frequencies. Which, again, has nothing to do with speaker design. Its the room.
