Even better, the 1.5" 4-ohms voice coil handles high heat temperatures without breaking a sweat so you can blast your favorite music on a regular basis for extended periods of time.

The high 94dB sensitivity of the PRO-X6.4BM lets you crank up the volume without any sound distortion, while the 125Hz to 12KHz frequency provides richer and more accurate tones that any audiophile will immediately notice. These loudspeakers can also handle up to 250 Watts RMS, making it capable of handling consistent and heavy usage. Put this baby on max volume and enjoy extreme volume levels with crystal clarity!

Over time evolution is inevitable. The same can be said for DS18's new Z series model of amplifiers! We took one of our best selling lines and upgraded every aspect of it. They now put out even more power, have more top of the line components, and are guaranteed to deliver amazing quantities of RMS power on demand. The previous Z series was very powerful to begin with and we packed all new DS18 branded boards with much more efficient electronics, and with all new heat sync casings to make an amazing amp line even more perfect for your needs. You have your pick of multiple 2 channel, 4 channel, and Monoblock amps in this line to power every aspect of your DS18 audio system.
