Our newest PRO GM rendition is an identical counterpart to our very popular PRO GM8 except now we offer it in 4 ohms instead of 8 hence the name PRO GM8.4. This monster midrange handles up to 190w RMS and 580w maximum power. A frequency range of 90hz to 10khz will ensure you get the most out of your frequency range, so you hit all your desired notes with ease. These speakers are a very good selection for someone who wants a little mid bass and very precise voice through their 8-inch speakers. These give amazing crescendos and very solid rock bottom notes. They come with non-pressed paper cones and steel pressed frames that hold a 30oz ferrite magnet. These are very solid speakers that will make even the most advanced audiophile smile.
