Never heard a non res in person, but 18" are quite enough under normal driving, but when you are passing someone, they definitely know it.
Z has very little sound insulation, if you are concerned about cabin noise, look into dynamat, or turn up your stereo.
I can carry on a normal conversation under normal driving with 18s, but I do not have HFC.
