FWIW - I love my Kef R500's!
I have them set up as my office system with a Musical Fidelity M6i Integrated and M1 DAC. Awesome system for the money; and pretty much full range.
Yes, a sub would go lower. But subs only work properly if they are meticulously selected and implemented. Otherwise they make it so much worse it's essentially unlistenable. The LS50 does a ton right. Either sell and go to the R series and don't look back, or get a very good sub and spend the time to place it and dial it in just right. If you go the sub route, I would suggest spending the money and buying it new so you can utilize the skills of your local dealer for proper setup and tuning.
