Versatility is paramount in large and small audio systems alike. Many DS18 fans have been wanting an 8 ohm version of our very popular NEO-R series of 6.5s. We have obliged the overwhelming requests by releasing our PRO-NRO6.8r. This Neodymium driven midrange speaker will be the loudest 6.5 we have while also handling the most power. The great thing about NEO motor structures is that you get better performance, higher wattage handing, better efficiency, and much lighter in weight than a traditional speaker with a ferrite motor structure. This is an 8 ohm speaker that handles 300w RMS and 600w MAX power with a DB sensitivity rating of 96db.
