The Terrain Dominating TDX46 is a 4" x 6" coaxial speaker pair that can handle up to 40W RMS power and is perfect when used in kickpods or custom enclosures on ATV, UTV, or other off-road machines. These speakers are designed to compliment any installation while delivering a full range sound experience for all types of music. These speakers feature a durable stamped steel basket and polypropylene woofer that can withstand the harshest trails. In order to get the most out of your music and hear it as the artist that recorded it intended you to, you need speakers that can reproduce the full range of sound frequencies. The TDX Series offers the best full range sound reproduction of any speaker in their class with particular focus on low frequency reproduction where TDX speakers play much lower than other models allowing you to listen to great bass even if you do not have room to install a subwoofer.
