I started with the T/7x and the now the Sire S 850s. My experience is that REL has come a long way in the last decade. They sound so good I cannot believe I went 30 years without subs.
One thing that really floored me was that I could listen to full, satisfying music QUIETER with subs. Before I would push my Wilson Sasha Vs hard to get full bass bloom. Now I don’t get listening fatigue from too much volume and even better my family isn’t subject to my loud music throughout the house.
