@shawarma Classic Audio Loudspeakers makes two speakers you might want to look at. The first is the T1 and the second the T3. They are 98dB so will be able to fill your room with a moderate amount of power (I suggest about 100 watts minimum). They are also full range and 16 Ohms. The midrange drivers have no breakups in the audio passband and are field coil powered, so they are very fast and also very smooth.
Since standing waves are an issue in any room with regular dimensions I would supplement them with a pair of subs placed asymmetrically elsewhere in the room to break up the standing waves. These subs should not be active above about 60Hz or so.
