For that sized room you would want to go with a large cubic inch speaker with a lot of piston power especially with classical and classic rock i would look into a vintage american speaker made before 1981 to fill the space with thick meaty sound with no loss of resolution or dynamics when you need them, when the volume gets turned up or the music gets complex in nature.
Persona B in a 36 x 27 room?
Is that too much space for the Persona Bs? I will augment them with two SVS SB4000 subs. I will drive the Personas with an HK990 integrated amp. I currently use Tekton Enzo 2.7s and they supply the dynamics and speed, but not the resolution. My music tastes center around classic rock sprinkled with some classical. Are the Persona Bs beefy enough for an area that size as I will occasionally turn up the volume? If you guys are aware of any other monitors (or small floorstanders) that are efficient, fast, resolve well and can fill a 36 x 27 space, I'm all ears. Thanks.
