HFTs?
I was browsing through the misc forum & came upon an old thread relating to near field listening (which also describes my listening room), and HFTs became a topic of that discussion. I did a google on "what are speaker HFTs?" and it took me to a site where they could be purchased at $399 per set per speaker. But what exactly are they?
