Input - Simply connect the amplifiers + and - outputs 
directly  to the red 
(+) and  black (-) input jacks on the back  of 
the enclosure (see diag. 
1). 
- Since the loudspeakers have a rated 
ce  of 
8R each, more than one speaker 
usually be wired to one amplifier channel (see 
See amplifier impedance load  below.) 
ating the Subwoofer SB-2 - Treat each input 
Subwoofer as an 
8R loudspeaker and wire into 
lete system accordingly (see diag.  3). (See 
er  impedance load  below.)

SerieslParallel - It is possible to utilize various serieslparallel hook-up topologies  to increase the  number  of loudspea 
driven  on an amplifier.  See diag.  4 for one example  of a serieslparallel  hook-up topology. 
Note: Mismatching  the speaker  impedance such that it is below the minimum impedance rating of an amplifier channel 
damage the  amplifier and  degrade performance.  If the application requires more than 
2 speakers...

because of differences  in the acoustical setting.  Since an enclosed  room 
presents acoustical  boundaries (walls, floors 
& ceilings), sound indoors 
exhibits quite  complex behavior. Each time  a sound  wave strikes  a boundary, 
part of  the waves  energy is reflected  and part is absorbed (see diag. 
1). 
Reflection & absorption  are dependent  on the freauencv  of the sound  wave 
and the angle at which  it strikes the  boundary.

HORIZONTAL VERTICAL 
Boundary Loading - This is a good  trick for increasing bass 
without  taxing the amplifier.  It is  also possible  to make a  system 
sound  too muddy,  so use  caution.  If you  move  the speaker from 
open space  to a wall,  bass  notes  will  increase by 
+ 3dB. If you 
move  it to  a 
2 boundary  corner, another  t3dB ... and another  t3dB 
for a  three  boundary  corner! (see  diag. 
4). 
frequencies go where you  point them. 
Simply  aim the center  axis of the 
speaker  into...

SOU 
Wind - Wind gives the illusion that a sound is coming  from 
a different  direction than it really  is. This creates  a 
re<ant 
propagation  vector 
(see diag.  1). When sound  propagates 
with the wind  it tends  to refract downward,  and against the 
wind refract upwards (see  diag. 2), (*refraction  is the term 
used to  describe  the bending  of sound).  From 
the speakers to  our ears 
- Since you usually  want a target 
background SPL  of about 70dB 
- 80dB to  your listeners, keep  in...
