A Discussion About Maximum Bass Output

 

 

When it comes to movies, the latest digital recording formats allow movie producers to       
incorporate an enormous amount of bass into their soundtracks. As a matter of fact, some 
movies produce bass that is more intense than larger

-

sized home theater subwoofers can  

handle. That is why virtually all modern subwoofers contain circuits that protect the             
subwoofer and its amplifier by limiting the maximum power that can be produced.

 

 

The amount of bass your system can produce is determined by several factors. For some, the 
bass produced by a single quality subwoofer like our Speedwoofer 10SMKII is more than   
plenty. Many of our customers report that they can

t turn up their subwoofer nearly all the 

way without upsetting other members of their family. However for some, any amount of bass 
is never enough. It isn

t our position to dictate how much bass is appropriate.

 

 

Another important factor is positioning. Depending on the position of the subwoofer, there 
will be peaks (where bass is more intense) and nulls (where bass is diminished). If you position 
the subwoofer so your listening position is in a null, you will not get adequate bass regardless 
of the size of your subwoofer or its volume setting. So, if you have the flexibility, spend some 
time determining the best position for your subwoofer.

 

 

If you have a very large listening room or simply desire more bass capability, we recommend 
considering a second subwoofer. This can add 6db of increased bass output, which is huge. 
This will allow both subwoofers to operate more efficiently with increased headroom for those 
explosive bass moments in movies.

 

 

Care And Maintenance

 

 

• 

Clean your subwoofer using a soft, moist cloth (Windex or water is recommended),      
preferably microfiber or lint

-

free cloth. Do not put your subwoofer in the washing ma-

chine.

 

 

 

• 

Be very gentle when cleaning the front of your subwoofer, trying not to put pressure on 
the woofer itself. 

 

 

• 

Be careful with liquids or beverages near your Speedwoofer. It does not play better when 
wet. Don

t place flowers or plants that require watering on top of the subwoofer. Watering 

your Speedwoofer will not make it grow.

 

 

• 

Please keep your Speedwoofer away from direct sunlight and heat sources.

 

 

• 

If you operate the subwoofer with the grille off, please make sure that the woofer does 
not come in contact with anything as it can be damaged.

 

 

• 

Wires can loosen over time. Periodically make sure all connections to the Speedwoofer are 
tight. If a wire loosens and touches other wires, your system could be damaged.

 

 

• 

Do not expose your subwoofer to extremely hot or cold temperatures.

 

 

• 

Your Speedwoofer may not be used as a flotation device.
