Quoted from Billy16:if you are asking strictly about DE pins, I'd say they are not worth the expense. I was disappointed in the moderate amount of difference they made in my TFTC. I'd save some cash and order something from Parts Express, then add a cheap powered sub (or maybe start with that first).
The DE speakers are fairly good; I have Flipper Fidelity set in my Time Machine and there isn't a whole lot of difference between the other DE pins in the line up. I can tell you the stockers are better than a lot of the China junk being sold.
