@johnrothschild, each and every Tannoy speaker I have heard R1, MX3, R3, DC6, Berkeley etc had a full sound never too far off neutrality. All of them good all rounders with plenty of Bass warmth.
However they would not be my first choice for Rock or Metal - there are better options out there for those genres. I’d start by looking at something from JBL, then maybe ATC, PMC etc.
In my experience those genres thrive primarily upon attack, dynamics and speed. Not especially subtlety and nuance.
Even some budget / party speakers can sound decent with Rock.
