I'm planning to add another subwoofer on my set up. Unfotunately I cant get another Rythmik LV12R. Im leaning towards NXG 500 or Mirage Omni 12. I dont know which on should I pair with my LV12R. Please give me advice. This is only all for movies. Thanks.
Is it because of sub size or finance? If it's the later, try to save up.
+1, save up. If you pair anything else with your Rythmik, you will end up with something that will smear out its signature sound. The subs you are contemplating will be less articulate and less capable, and would be overdriven if asked to keep up with something like the Rythmik in deep bass. In other words, they will hurt more than they will help.
