uncovered floors or scatter rugs, small amounts of furniture, hard
walls) can be improved by the addition of rugs and heavy draperies,
which also serve to eliminate echoes and standing waves. For acous­
tically “dead” rooms (e.g., those with wall-to-wall carpets, heavily
upholstered furniture, large amounts of draperies), furnishings should
be arranged so that speakers have unobstructed sound transmission
paths to the listening areas. Finally, since no room is acoustically
perfect, you are encouraged to use your amplifier or receiver tone
controls to adjust the sound for your maximum listening enjoyment.
5. TECHNICAL INFORMATION
SPATIAL CHARACTERISTICS Asymmetrical Design for opti­
mum stereo reproduction utilizing side wall reflections. A Direct
Energy Control for adjustment of ratio of direct to reflected sound
at high frequencies.
SPEAKER COMPLEMENT Woofer; An 8-inch high efficiency
design optimized for operation in a moderate size ported en­
closure. The high frequency response is uniform to over 3 kHz
for maximum utilization of the Dual Frequency Crossover Network.
Tweeter; 3-inch high sensitivity design. This tweeter Is designed
for performance down to 1400 Hz and has exceptionally smooth
and extended high frequency response. The on-axis frequency
response rises at high frequencies to maintain constant total
energy.
Crossover Network: The crossover network utilizes a Dual Fre­
quency design whereby the transition frequencies of the woofer
and tweeter are separated by over one octave. The network con­
sists of an inductor, two resistors, and a high grade film capacitor.
Computer style wire-wrap connections are used for maximum
reliability. Crossover transition frequencies are 1400 Hz and
3000 Hz.

301 should provide you with many years of enjoyment.
7. IN CASE OF DIFFICULTY
If you suspect a problem with one of your Model 301 speakers,
it is worth a few minutes of your time to determine whether the de­
fect is in your speaker or in some other portion of your high fidelity
system.
IF ONE SPEAKER SOUNDS DEFECTIVE, first disconnect the
speaker that is operating properly by disconnecting the wire
from the output terminals on the rear of the amplifier. Next,
disconnect the wire running to the speaker which sounds de­
fective and connect it to the output terminals of the amplifier
channel which you are sure is operating properly. If the speaker
now seems to be operating properly, the defect is in another part
of your hi-fi system.
IF THE TROUBLE APPEARS IN BOTH CHANNELS, connect your
Model 301s to another amplifying source or high fidelity system
that is operating properly. If the trouble is no longer apparent, the
difficulty is not with the speakers.
