My TV has a reasonable sound through the built in speakers (LH 65" OLEDCX) but could do with a little extra bass. My thought is to use a wireless/ bluetooth sub or even just a normal speaker with good bass response connected using the TV bluetooth headphone function. The only problem that I can think of is timing delays between the internal speakers and the sub. . I appreciate the setup that I am thinking about will still have some bass coming through the tv speakers and there could be phasing issues because of that but as the bass is so light to start with I cant see this being a real problem. It would be great if TVs just had a sub out or even better a wireless sub out. Has anyone tried this - any major problems or other solutions as I really do not feel the need to purchase a sound bar?
