1. TRUAUDIO THE SOUND OF INNOVATION Red Mountain Subwoofers By TruAudio Powered subwoofers RM 15Sub RM 12Sub and RM 10Sub Introduction TruAudio is proud to launch our first 100 USA built subwoofer in St George UT Since 1997 TruAudio has been designing and engineering some of the finest loudspeakers available Because we came from the installation industry each of our products is designed to adapt to the specific installation environment Obviously with our architectural products it s a lot easier to make a speaker disappear but even our freestanding speakers look great and easily blend into the room s d cor The Red Mountain powered subwoofers are some of the finest available today It took over two years to design a speaker system that offers the best video sound reproduction in either 5 1 6 1 7 1 and even 9 1 Model RM 12Sub RM 10Sub These powered subwoofers in this series leaves nothing to be desired After over 1 year of engineering and testing the RM 12Sub and RM 10Sub are the last link needed to complete the TruAudio theater package These subwoofers use a black anodized Aluminum woofer and a slot port design All those fancy words really mean a specially designed woofer that will provide tons of bass at high volumes for extended periods of time This is all driven by a huge super powerful A B power amplifier build exclusively for this cabinet and driver array The RM 12Sub features a 300 watt amp and the R2. frequency percussion instruments or music with a continuous bass line Try it first in the 0 setting and then listening to the same music in the 180 setting Then set the switch to the setting that reproduced the most bass Furniture wall coverings subwoofer location all can affect this so if any of these things get changed or added you will need to go through this process again This setting is also very important to set correctly if you are using two subwoofers in one system In the case of a two subwoofer system you need to have these set opposite of each other For example Sub 1 will be set at O and Sub 2 will be set at 180 Power Switch This turns the AC power to the subwoofer either on or off Final Adjustments Once all the speakers are wired and back in place turn on the amplifier and or receiver Start at a minimal volume until you have a chance to hear the total output of the speakers Use a movie or CD you are familiar with Remember the amount of bass you hear and the stereo image quality will be affected by a number of different factors including the rooms shape and size wall coverings and furniture location Listen to a variety of music selections to see the bass level If there is too much bass move the main two front speakers further away from any nearby walls So obviously if you wish to have more bass move these same speakers closer to the wall Most receivers and preamps will have adjustment
