Speaker Cable Recommendations And Connection Instructions

Wire Gauges

For very short distance speaker cable runs (less than 25’) 16-gauge, stranded, twisted pair speaker cable may be used. For speaker cable runs between 25' and 75', 14-gauge, stranded, twisted pair speaker cable is recommended. For speaker cable runs greater than 75', 12-gauge, stranded, twisted pair speaker cable is necessary. For runs exceeding 150', please contact tech support for proper wire gauge.

Input connections are provided on a convenient recessed terminal block located on the bottom of the loudspeaker. This terminal block includes a clear weather resistant cover which should be re-installed after terminating the speaker cabling to prevent corrosion in outdoor applications.

Allow an adequate service loop for this connection to allow tilt of the loudspeaker. If the speaker is tilted above parallel to the ground, water may collect in the speaker cabinet causing damage — the product should not be installed tilted upwards!

Amplifier Considerations

Consult your amplifier owner’s manual to confirm power output at the rated impedance.

The AHSUB15S exhibits an 8Ω (nominal) impedance.

(x2) AHSUB15S paralleled will present a 4Ω load to the amplifier.

(x3) AHSUB15S paralleled will present a 2.66Ω load to the amplifier.

(x4) AHSUB15S paralleled will present a 2Ω load to the amplifier.

ATLAS SOUND speaker system specifications list RMS power handling.

As a reference, peak power = RMS x 1.414.

These ratings should be considered in selecting the best amplifier to power the speaker system.

For general use, amplifier output should match or exceed the RMS rated power of the speaker system (250 Watts).

For increased headroom and dynamic reproduction, the amplifier’s output should match or exceed the peak power rating of the speaker system (354 Watts). In situations where experienced professionals are operating the speaker system with proper limiting and frequency control devices inserted into the signal path and adjusted properly, amplifier output may meet, but should not exceed 2x the RMS power rating of the speaker system (500 Watts). Utilizing the Atlas Sound model CP700 power amplifier will allow you to easily match required power ratings for most any installation. Visit www.AtlasSound.com for more details on this product.
