"Testing the central feature, we found the DXA-4's sonic quality to be excellent. On a long run of cable, no noise was evident and on the bench we measured a near ruler flat frequency response from 40Hz - 15KHz which was just -3dB down at 20Hz and 20KHz. In layman's terms, this box meets professional specifications." Computer Video Magazine "we were highly impressed with this product.
