Well said.All action sequences will have BGM. A good sub that is accurate and detailed is a must for movies.Well there are people listening to poor quality subs and enjoying movies as well but that’s a different topic. Mass market is all about boom boom and that’s is why these Sony HTIB and sound bars are liked by such market. Talking in an enthusiast context or some one like me who have experienced so many set ups and subwoofers i can confidently say any subwoofer with spl alone is not enough to get the best from movies. If your reference and experience is with average subs yeah any sub will do.We shouldn’t conclude with limited experience.Only when your reference is correct you will get an idea of how a scene or music should sound. Past 3 years alone I would have got 10 or more subwoofers from multiple brands all with high spl for my room size. So for people who are reading this thread looking to get subwoofers for movies please don’t get misguided by wrong claims. A sub with good details and texture will give a better movie experience then just any sub with spl aloneWell many Movies have musical soundtracks too & thats when a musical sub comes in play, yes you do loose the low end grunt & vibrating tables/windows etc effects. I was using my Rel subs for music & movies but now they are only used for movies as i got floor standers which are adequate in bass response for me (not a bass junky) My point is even Musical Subs have their benefits for movies..
