I'd expect speakers to break in faster than subs because the suspension and surround for a sub is stiffer. Ian is sending me a second 800v4 so I'll have a chance to "test" if I can hear a difference. Likely not though since apparently the second sub spent time in the chamber being tested for gut punch mode.
