Thank you for purchasing Pure Acoustics’ products, and welcome to the Pure Acoustics family of satisfied customers!   

 

Pure Acoustics was established to fulfill the need for high quality speakers of exceptional design at an affordable price.  

After years of research and development, and by manufacturing all parts ourselves -- from the voice-coil to the 

uniquely-designed crossover -- Pure Acoustics is able to offer you speakers of superior value.     

 

Each subwoofer component has been designed and engineered with first-rate materials to produce exceptional sound.  The sleek 

cabinetry encases a deceptively powerful woofer that delivers a clear, open bass with incredibly low distortion, even at high volumes.  

This subwoofer offers the best of it all – high-quality sound, hand-made solid construction, and a remarkably stylish appearance.   

 

We welcome you to witness the results.  Our team’s dedication to quality, reliability and attractive design has created some of the 

best-value subwoofers you can find today. 

 

Reading this manual fully (the complete manual) will help you to set up your subwoofer properly and reward you with a fine listening 

experience.  Pure Acoustics distribution centers in Europe, Asia, Australia and the Americas will be happy to assist you with any 

questions you may have.    Please look for the distributor nearest you on our web site, www.pure-acoustics.com.     

 

Before you start, make sure all your equipment is switched off and the amplifier volume is on low. Make sure the positive (+) and 

negative (-) are connected to the appropriate terminal.   

 

SUBWOOFER LOW-LEVEL CONNECTIONS 

Using an RCA cable, connect the Pre Out (subwoofer) on your receiver to a Y connecter.  Then connect the Y Connector to the 

RCA Line in on your subwoofer. 

SUBWOOFER HI-LEVEL CONNECTIONS 

Connect a speaker wire from your amplifier’s positive (+) output-left speaker terminal to the subwoofer’s positive (+) input-left terminal. 

Connect another speaker wire from your amplifier’s negative (-) output-left speaker terminal to the subwoofer’s negative (-) left-input 

terminal.   Connect a speaker wire from the positive (+) output-left speaker terminal on the subwoofer to the positive (+) input 

terminal on the front-left speaker. Connect another speaker cable from the negative (-) output-left speaker terminal on the to the 

negative (-) input terminal on the front left speaker.    Repeat the same step for the right-side front speaker.     

 

Make sure the subwoofer switch is in the OFF position, rotate the GAIN control to MIN and set the FREQ control to the middle 

position.  Plug in the AC power cord to your electrical outlet.  Turn on your amplifier and subwoofer and play your favorite music.  

Gradually increase your amplifier’s volume to your desired level.  Gradually increase your subwoofer GAIN level to your desired 

bass level.  Adjust the FREQ control to a point where the subwoofer and rear speakers perform to your satisfaction.  Toggle the 

PHASE switch between the REV and NOR positions to see which one sounds better to you.    These adjustments are used to match 

the subwoofer bass reproduction with that of your main speakers.  You can now leave the AUTO/ON/OFF switch in the AUTO 

position.  This position is voice-activated; your subwoofer will switch on automatically only when the subwoofer receives an audio 

signal from your amplifier.     

 

For optimal results, try a few different types of music.
