I own stand mounts as well as floor standers ,and by asd8ng a subwoofer - A Quality one ,two even better more even bass , the bass fundamentals just donot effect the low frequencies ,but also up into the lower midrange .
when setup properly the music as a whole is much more substantial as music
as a whole .i have been into audio for a long time and owned a Audio store fir 10
years and have had the opportunities to compare most every type of Loudspeaker type ,and setup in rooms . Whst ever you do is totally up to you ,but there is ample proof out there 1-2 subwoofers of respectable quality is a win win ..
svs 3000s has a great app to find tune your system , JL Audio, Rel , Kef , and several others are verygood.
