OUR PART # QUADRA10-BLACK
Peavey's Quadraâ„˘ 10 is an injection-molded, two-way speaker system, engineered in the AA tradition to provide superior performance from a compact and durable package. The enclosure is made from very high impact, injection-molded polypropylene in a trapezoidal shape, with extensive ribbing and bracing, and the grills utilize perforated metal protected by a high quality vinyl coating process, and has an integral foam inner layer for environmental protection.
The two-way system is comprised of a 10" long throw heavy-duty woofer, and a water-resistant treated cone and dust cap for superior environmental stability. The high frequencies are handled by a 14XTâ„˘ 1.4" titanium diaphragm compression driver, coupled to a 1" Quadratic Throat Geometry horn, molded integral to the cabinet. This horn provides outstanding dispersion coupled with a well-controlled pattern, and a smooth, even response.
Utilizing Quadratic Throat Hornâ„˘ technology, under US patent 6,059,069, the horn has lower distortion than many popular CD horn geometries.
Input connection to the system is made via screw terminal strip (one pair) for full-range inputs.
The internal passive crossover features Sound Guardâ„˘ II tweeter protection circuit, an advanced topology crossover with high performance components, to provide high power handling and reliability. Peavey's proprietary high-frequency driver protection circuitry, Sound Guard, provides long and medium-term driver overload protection without impairing musical transients or dynamics. The crossover provides driver roll-off and protection, as well as driver EQ for the woofer and horn; the sum total is a crystal clear and very smooth response. High-quality, reliable crossover components include polypropylene capacitors, and high current inductors and input connectors. The optimal integration of the crossover with the selected drivers results in a smooth frequency response from 74 Hz to 18 kHz.
Despite its compact dimensions, this enclosure can put out some very serious sound levels, and take 500 Watts program of clean amplifier power, resulting in an outstanding amount of clean coverage with amazing clarity.
Frequency response measurement is useful in determining how accurately a given unit reproduces an input signal. The frequency response of the Quadra 10 is measured at a distance of 1-meter using a 1 Watt (into the nominal impedance) swept-sine input signal. The selected drivers in the Quadra 10 combine to give a smooth frequency response from 74 Hz to 18 kHz.
Beamwidth is derived from the -6 dB points from the polar plots which are measured in a whole space anechoic environment. Q and Directivity Index is plotted for the on-axis measurement position. These are specifications that provide a reference to the coverage characteristics of the unit. These parameters provide insight for proper placement and installation in the chosen environment. The blending of the components of the Quadra 10 exhibit a desirable beamwidth and directivity suitable for sound reinforcement applications.
There are many different approaches to power handling ratings. Peavey rates this loudspeaker system's power handling using a full-range form of the AES Standard 2- 1984. Using audio band 20 Hz to 20 kHz pink noise with peaks of four times the RMS level, this strenuous test signal assures the user that every portion of this system can withstand today's high technology music. This rating is contingent upon having a minimum of 3 dB of amplifier headroom available.
Second and third harmonic distortions vs. frequency are plotted in figures 5 and 6 for two power levels, ten percent (10%) of rated input power and either one percent (1%) of rated input power or one Watt, whichever is greater. Distortion is read from the graph as the difference between the fundamental signal (frequency response) and the desired harmonic. As an example, a distortion curve that is down 40 dB from the fundamental is equivalent to 1% distortion.
