Should I spike my Forte IIIs

Isoacoustics out of Canada makes some relatively cheap stuff that looks interesting.

I always tried stuff for myself.
Best way to learn.

Yes. Use cheap vodka or Everclear in smaller proportions. 

Your room looks like a place to relax and forget audiophoolishness.

To spike or not is a YMMV thing. Your setup appears more of a "gathering/sociaizing" layout.
If it sounds good to you, then that's all that matters.

The "E" ticket seat is obstructed by the coffee table, and the speakers look like they could be pushed out more, maybe a wee bit closer together.....I just ruined the aesthetic of your lovely room-nevermind. Enjoy
