The terminals on the HEX component mid-bass drivers 
feature a recessed mechanism to allow direct 
connection of speaker wire up to 12 gauge.  This 
allows for a very clean and secure connection without 
exposed terminals.  Strip the end of the wire and 
insert into the terminal and gently tighten down the 
terminal screws with a small manual Philips 
screwdriver.  Power screw guns are not recommended 
as they can cause the terminals screws to strip.  Do 
not solder or tin the wire before connection, it can lead 
to failure if terminal screws are tightened too much.

The illustration above shows the parts included and correct mounting assembly of the HEX 
component mid-bass drivers.  Grill is optional.  Be sure to check the available mounting depth 
before installation begins.  Use of the foam gasket is recommended to ensure a proper seal 
between the speaker and mounting surface.

Each HEX component system comes with a pair of model specific adjustable crossovers.  Under 
the  cover there are a pair of jumpers that control tweeter and RAF levels.  These jumpers are 
designated “TWEETER” and “REAR”.  The tweeter adjustment has settings for -2dB of 
attenuation, +2dB of gain or 0dB which is flat. 

Each HEX component crossover has a third set of outputs marked “RAF”.  This stands for Rear 
Acoustic Fill.  This output can be used to power and additional speaker off the same channel 
without effecting the impedance load on the source unit.  The level of this output is determined by 
the jumpers in the crossover marked “REAR”.  The jumper has settings for -10dB of attenuation, 
-5dB of attenuation or off. When off, the RAF outputs are flat, or have no attenuation.

When flush or surface mounting tweeters, make sure 
desired location can accommodate the hole sizes 
and depth required.  Mount cup using provided 
hardware, flush mount illustration shown on right.  
Mount surface cup with provided screws in tweeter 
mounting kit.  Snake speaker wires through tweeter 
cup, connect tweeter to wires,  and snap tweeter into 
cup by pushing down gently.  Be careful not push on 
the center of the tweeter grill.

The following illustration shows how to connect one channel of the Hex component system.

HEX speaker systems offer the ability to run a true 3-way component system by just using a 
special add-on kit, model number S6.0mx3.  This add-on kit is compatible with all HEX component 
systems and is fully programmable for high pass frequency and attenuation.  The add-on 
crossover also is bi-amp ready (be sure to flip the bi-amp switches).  See illustration below for 
wiring instructions.
