Only the the best grand pianos have any bass. Your cheap 43" tall console piano for apartment use will not have much bass to speak off. The strings are too short, the box is too small. We have to restrict ourselves to True Scotsman's pianos.

Bass is easy to obtain out of a synthesizer: just make sure you have a subwoofer in the speaker system. It doesn't have to be a True Scotsman's synth or subwoofer.
