                                 Our CI series do not include an enclosure. For many this might seem a significant disadvantage! However, for many customers, this is in fact a great advantage. Consider some of the applications: 
                                 Architectural - subwoofers built into a dedicated room  
                                     Infinite baffle - a specific class of Architectural subwoofers
  Custom Dipole designs 
  Custom Enclosure designs - to match interior decor
  DIY enthusiasts - those who prefer to build their own 
                                With  our CI series, you have the option to build your own enclosure, or source a local cabinet maker. International customers can also save on shipping.  
                                Customers who would prefer to buy a finished product fully assembled are recommended to choose from our finished subwoofer range.

                                We have teamed up with GR Research to provide cutting edge new products for custom install applications. First we start with GR Research paper cone drivers which have been designed to work with our Direct Servo technology. Three different versions of this driver are supported: 
                                
                                    - 
                                      
single 1.8 cu ft sealed box  
                                     
                                    - 
                                      
dual driver 3.6 cu ft sealed box  
                                     
                                    - 
                                      
open baffle / infinite baffle 
                                     
                                   
                                  For open baffle and infinite baffle enthusiasts, we present the only servo solution on the market. The advantage of the paper cone is that a smooth and extended upper response is possible. 
                                  
                                    
                                      | GR research driver: Features low mass paper cone for excellent transient response and a smooth extended response.  | 
                                     
                                   
                                  New subwoofer amplifiers 
                                  In addition to existing range, we now provide subwoofer plate amplifiers featuring parametric EQ, balanced inputs and higher powered models.  
                                    A370 PEQ3 
                                      370w plate amp featuring parametric EQ 
                                       
                                      H600 PEQ3  
                                    600w plate amp featuring parametric EQ 
                                       
                                      A370 XLR2/3 
                                      370w plate amp featuring balanced inputs 
                                  What's the difference? 
                                  With other products on the market, after purchase you are on your own. It's up to you to design your own box and you bear all the risk. Many will not achieve the desired bass extension without modification to the amplifier which will void warranty. Many amplifiers feature bass boost which will not suit most serious enthusiasts. It's very common for diy enthusiasts to modify the amplifier to remove this boost at their own risk. None of our products require such changes. All of our amplifiers have been designed for the driver supplied and will achieve the target response without modifications.  
                                  You don't have to be an expert to use our CI products effectively.
