PROBABLY NEEDS NEW CAPS?I HAVE TWO OF THESE PSW-6's POWER AMP MODULES LISTED ON EBAY. EACH ONE IS BEING SOLD AS-IS.MATCHED PAIRTHIS LISTING Serial No: 00346759OTHER LISTING Serial No: 00346758From Meyer Sound Labs:Meyer Sound PSW-6Sound pressure propagates from the front of the speaker using four frontloaded cone drivers and is steered away from the rear of the cabinet by two rear-mounted cone drivers. This is accomplished through a complex electrical response relationship between multiple amplifier channels and critical geometry between the front and rear transducers. This phase relationship cancels low frequency energy in the rear lobe and is additive in the front, resulting in higher efficiency and greater SPL. Recent advancement in Meyer horn technology has afforded precision control of the coverage patterns of mid and high frequency sound but precise control of low frequency coverage remained problematic due to the enormous size of horns needed to control low frequency sounds. To achieve directional control of a frequency, its wavelength must be less than half the diameter of the horn. For example, control of a 30 Hz tone would require a horn 20 feet in diameter. Similarly, any array of subwoofers would have to cover a similarly large area to achieve directional control of low-frequency sound.In an unprecedented historical achievement, Meyer Sound self-powered PSW-6 is the first subwoofer to exhibit a true cardioid coverage pattern throughout its entire operating range. This makes it the first subwoofer to offer directional control of low frequencies. Covering more than two full octaves, the PSW-6 has a front to back SPL ratio of more than 15dB, and typically more than 20dB, from 30 Hz to 125 Hz. The horizontal and vertical coverage patterns of the PSW-6 are symmetrical, ensuring consistent SPL and frequency response throughout the coverage area.The research which lead to the development of the PSW-6 set out to control low frequency sound in a much smaller space for applications where the size of large arrays were impractical or impossible. Research done using Meyer SoundÕs own Source Independent Measurement (SIM¨), and the Multipurpose Acoustical Prediction Program (MAPPª) allowed Meyer to create exceptionally accurate computer models of low frequency speaker interaction. Out of this experimentation the PSW-6 was born.The tight response pattern of the PSW-6 helps to steer all frequencies away from the rear of the cabinet, eliminating much of the reverberant noise traditionally associated with large scale full-range speaker arrays. Additionally, the tight response pattern allows the PSW-6 to be placed in close proximity to walls without the traditional problems associated with subwoofers and subtractive boundary conditions. Control of low frequency sounds through cancellation, or more accurately, directional steering is only possible in exceptionally linear systems. Linearity is critically important to directional steering as the relationship between transducers must be consistent even while the music changes in level. Nonlinearity or distortion above a few percent would make directional steering impossible. For nearly twenty years, Meyer Sound has been committed to developing accurate, high-quality, linear sound systems. As a result of this continuing effort, Meyer Sound has developed powerful, low distortion transducers unequaled in their linear attributes. The cardioid pattern refers to the heart-shaped polar pattern of the speaker (see illustration next page).Operating Frequency Range, 30 Hz - 125 Hz (-6 dB points) 32 Hz - 100 Hz ± 3 dB1Phase Response, ±50¡ 40 Hz - 130 Hz2, 30 Hz - 125 Hz (-6 dB points)Maximum SPL, 140 dB @ 1 meter3Dynamic Range, >110 dBTransducers=Two 18" MS-818 cone drivers, Four 15" MS-415 cone driversAmplifiers Type=Complementary power MOSFET output stages, class AB/HOutput Power=2480 Watts (620 Watts / channel)4THD, IM, TIM=< .02 %Audio Input Type, 5 k½ impedance, electronically balancedConnector, XLR (A-3) male and femaleNominal Input Level, +4 dBu (1.23 Vrms)AC Power, Connector, 250V NEMA L6-20 (twistlock) inlet or IEC 309 male inlet, Automatic voltage selectionOpearional Voltage Range, Turn on: 85 VAC; Turn off: 134 VAC; 50/60 Hz, Turn on: 165 VAC; Turn off: 264 VAC; 50/60 HzMax Continuous RMS Current (>10 s), 115 V: 14 Arms 230 V: 7 Arms 100 V: 16 ArmsMax Burst RMS Current (<1 s), 115 V: 26 Arms 230 V: 13 Arms 100 V: 30 ArmsMax Peak Current During Burst, 115 V: 36 Apk 230 V: 18 Apk 100 V: 42 ApkSoft Start Turn-on, Inrush current <12 A @115 VPhys i c a l, Height: 42.75"; Width: 42.52"; Length: 22.4"; Depth: 32.28"Weight, 442 lb (201 kg)Enclosure/Finish, 12-ply hardwood/black textured This Power Amp Module Is Heavy And Large.Stringent packing ensures that your items will be professionally packed to arrive in the same pictured condition.
