yeah I’ve heard of them and psa.\nIll never be able to afford those or let alone move them . Oddly there big woofers don’t go below 60-70 hz!!!\nI said they do exist but super expensive!!!!\nIn general most speakers aren’t over 6.5-8” max size .\nSome towers have 4-6” woofers, brands charge a ton for small speakers like kef r .\n\n\nActually, you'd be surprised at how much bass that most people hear and love comes from 50-80 hz. Below that is mostly things rattling in your room.
