Worth paying ~$300 more for the Q990F v Q990D?

I have the chance to get the Q990D Soundbar setup for $689 versus the Q990F setup for $968. I was already sort of leaning towards the Q990D because, based on my research, the Q990D has specs that are either the same as or sometimes arguably better than the Q990F, but the only real change to the F was the subwoofer, which supposedly takes some of the vibration out of the D model and is more compact. I would think the extra $300 isn't worth it for the F, but wondering peoples' views who have used them.
