The 1528 series use machined solid copper speaker terminals for maximum conductivity. With long-term reliability in mind, we use rhodium coating to ensure excellent corrosion resistance while maintaining stable electrical contact over time. Without ferrous materials anywhere in the signal path, the terminals eliminate magnetic interference at the connection point, preserving signal purity from amplifier to speaker. 

The entire series features dual binding posts with a custom made jumper connecting the top and bottom terminals, making it possible to Bi-Wire or Bi-Amp all speakers in the series by removing the jumper and use separate connections on the HF/Mid section and Woofer section.  

Tower, Bookshelf and Monitor speakers also feature level-jumpers for the HF and midrange section to adjust levels from +2dB, 0dB to -2dB. Made of the same high quality materials as the terminals.
