From the Manufacturer: The 600-HP is a self-powered, high-output subwoofer that may be used in both flown and ground-stacked configurations. It is available in three versions: as a portable version with handles, for installation without handles, or with rigging hardware. When fitted with the optional QuickFly MRF-600 rigging frame, the 600-HP is designed to rig directly with the MICA compact, high-power curvilinear array loudspeakers. The versatility of the 600-HP also allows it to be used with a variety of other Meyer Sound self-powered loudspeakers — including the CQ-1, CQ-2, UPA-1P, UPA-2P and UPJ-1P — in fixed and touring applications. The system features two specially designed high-power 15-inch cone drivers, engineered to provide optimal performance in subwoofer applications. The high-excursion, back-vented drivers have 4-inch voice coils, and each is rated to handle 1200 watts (AES). The two cone drivers are housed in a rectangular, optimally tuned and vented enclosure that is the same width as MICA, and a few inches higher and deeper. The enclosure geometry makes vertical ground-stacking easy and convenient. All versions include plastic skids on the bottom of the unit to prevent damage to the enclosure or the unit below; the skids align with slots on the cabinet’s top to ensure secure stacking. Operating frequency range is from 36 Hz to 150 Hz, with a peak SPL at one meter of 138 dB. Each cone driver is driven by a channel of the integral two-channel class AB/H amplifier with complementary MOSFET output stages. Total output power is 2250 watts (4500 watts peak), providing the system with sufficient headroom to accommodate the most extreme sound reinforcement demands with ease. The circuitry includes TruPower limiting to extend the life of the drivers and hold long-term power compression to less than 1 dB. The amplifier, control electronics, and power supply are integrated into a single, field-replaceable module that is mounted into the rear of the enclosure. The optional MRF-600 rigging frame uses captive, rigid GuideALinks contained within recessed guides in the lower front and rear corners of the enclosure. A slot and convenient pinned handle allow the link to be moved and pinned for arraying or storage. The versatility of angles achieved by using combinations of front and back positions allows a MICA array suspended under 600-HP subwoofers to be uptilted for balcony coverage up to 15 degrees, or downtilted to 6 degrees with respect to the 600-HP. The 600-HP can make use of the optional MG-MICA rigging grid to accommodate a variety of flown and stacked configurations. The durable enclosure is constructed of premium birch plywood coated with a black, textured hard-shell finish, with a powder-coated, hex-stamped steel grille lined with acoustical black mesh to protect the drivers. The exterior dimensions of the 600-HP are suitable for both European and U.S. trucks, and it can securely travel in stacks using the MCF-MICA caster frame, or MDB-600 dolly board when not fitted with rigging frames. Options for the 600-HP include weather protection and custom color finishes for fixed installations and other applications requiring specific cosmetics. The RMS remote monitoring system — standard with the rigging version and optional with other configurations — allows comprehensive monitoring of system parameters on a Windows-based network
