SPATIAL CHARACTERISTICS
The Bose® 601TM Series II system is a high performance
floor-standing Speaker designed to
achieve the highest level of spatial realism and spectral
accuracy in a non-equalized Direct/
Reflecting® Speaker system. The new 601 Series II Speaker
incorporates two new concepts in
Speaker technology: The Free Space® array, which allows the
drivers to radiate freely in any
direction, providing exceptionally Realistic and
natural-sounding energy distributing in almost
any listening room. The second new concept is the Sub-port
Enclosure System, figure 1. Each
woofer has its own enclosure that has damping material and a
sub-port. The sub-ports are
tuned to operate in the frequency range of 200-300Hz,
providing principal sound radiation in
these frequencies through the sub-port rather than the cone.
The sub-ports are coupled to the
main port of the Speaker, and with the new extended range
woofers, tweeters and crossover
network, the 601 II Speaker takes maximum advantage of this
new technology.
Speaker CONFIGURATION
WOOFER: Two new high-efficiency 8" woofers designed for the
sub-port enclosure. Each
woofer has a long excursion voice coil and suspension, plus
a 14 Oz. magnet, providing high
output capability. Uniform response of the woofer is over
2.5KHz with use of the Dual
FrequencyTM crossover network. One woofer is directed
forward while the second woofer is
directed upward, which helps create a balance of reflected
and direct energy in the listening
room.
TWEETER: Four 3" wide-range high sensitivity tweeters per
enclosure provide flat power
radiation beyond 15KHz. The response extends down to 1.5KHz
for use with the Dual Fre-
quency crossover network. Two tweeters in each Speaker
enclosure are directed outward so
that most of the sound energy is reflected off the back and
side walls. One tweeter is posi-
tioned so that the sound energy is directed towards the
center of the room and the final
tweeter is positioned to reflect sound off the back wall
between the speakers and into the
room, providing a strong center stereo image by filling the
"hole in the middle".
DUAL FREQUENCY CROSSOVER NETWORK: Located in the top woofer
cup, the crossover
network consists of two capacitors, two resistors, and two
tweeter protection lamps. The Dual
Frequency crossover network is designed to offer performance
advantages by deliberately
operating both the woofers and tweeters simultaneously over
a significant part of the frequency
range. We have designed the crossover network to have
separate transition frequencies for
the woofers and tweeters. By using separate frequencies, an
overlap in response of almost
one octave is achieved, providing smoother frequency
response in the crossover region.
Careful design of all Components in the crossover network
matches woofer and tweeter re-
sponse, eliminating phase cancellation and assuring accurate
frequency and transient re-
sponse.
Enclosure: A sub-port enclosure system for maximum
efficiency, minimum cone motion and
placement versatility. Cabinet is constructed of walnut
grain vinyl laminated to particle board.
Note: The early version of the 601 II Speaker has three
input terminals. Later versions had
two input terminals. Refer to the schematics and crossover
part lists in this manual for differ-
ences.
