Phase Technology PC-8.5 speakers sound flat


Hello,
I recently purchased a pair of PC-8.5 speakers and recently hooked them up to my recapped Pioneer SX-850.  They sound completely flat with no high end.  Has anyone had experience with them?  Could it just be tweeters, or somethin I am missing?  Any direction very much appreciated.
What is the purpose of the gold clips between the two positive and two negative speaker connections?
Thank you.

The gold clips are jumpers for the woofers and tweeters.  The2 positives and 2 negatives need to be connected.  If not, no highs.
