More than any other speaker in this group except perhaps the Polk, the BX1 looks like a high-end product, with its walnut finish; its 1-inch, gold-finish C-CAM (composite ceramic metal) tweeter; and its 5.5-inch C-CAM woofer. Unusually, the woofer is attached to the back panel, not the front, so its vibration won’t be as easily transmitted to the front panel.
