I wouldn't expect anyone to be able to hear such a fine difference between using 1 or 2 spacers; but maybe my ears aren't as good as yours. In my experience it's more important to have a good power amp, correct speaker location away from the back and side walls, proper toe-in, and using a smidge of equqlization found in the best software such as Amarra to help enhance low bass. I can spend endless time getting these things right.
I've never tried your specific experiment, but I have more than a little experience with the 1.7. Best wishes in your experiments.
