High quality medium duty subwoofer with high efficiency and long linear excursion. While these were designed for pro audio use in medium power subwoofers cabinets they are also great for infinite baffle or open baffle designs such as H-frame thanks to a relatively high Qts. High end low power DIY audiophiles will love this in large vented boxes also. See the datasheets in the images. A special buy allows us to bring you a very limited Qty of these woofers at an extremely low price so get some before they run out.
