The ISP Technologies XMAX112H Subwoofer has been carefully designed to provide a level of performance, both in terms of SPL output and low frequency extension equal to the best dual 18 cabinets, yet at a smaller size and 63% (-2dB) of the power consumption.  Alternately, at equal input power, the XMAX112H will typically be 2 dB louder than a dual 18.  This is very important in many facilities with limited power availability.  Added to this are the advantages of lower distortion level when pushed hard, and the longer throw of a horn loaded system.  When used in groups, the low frequency sensitivity is increased and the LF extension is enhanced.

     The 12’’ driver is specially designed for horn loading, with an extremely strong cone, massive magnet structure, and special suspension and voice coil for very large linear cone excursions - up to 3x that of typical speakers.  This is coupled to a carefully designed folded horn with high compression ratio for high sensitivity and a 9 ft. path length for LF extension into the 30 Hz range.  In addition, the driver has a massive 4’’ voice coil, multiple cooling vents, and a 1000-watt long-term (AES) power rating.

    Standard with the system is a 1400-watt rms amplifier that is specifically designed for use with the speaker.  This amplifier features ISP’s patent pending DCAT high-current amplification technology.  A cooling fan automatically switches on when needed.

   The system is available in two configurations.  The XMAX112H is the install version without handles.  The XMAX112HT is the touring version with handles and two built-in corner castors for hand-truck type movement.  The width of 22.7’’ allows for enhanced truck pack with 94’’ (7’ 8”) internal truck widths.

Features:

• High performance horn loaded subwoofer, optimum tradeoff between performance and size.

• Equals the performance of dual 18 ported cabinets with 63% of the power, 85% of the size, lower distortion, and longer throw.

• 1400 Wrms amplifier with bypassable electronic crossover and high-pass output built in.

Note: Most dual 18 boxes specify an unrealistically high peak SPL with 4000 or more watts of input power.  If you use that much amplifier power to drive them, you are wasting money on amps, driving them to horrendous distortion levels below 100 Hz, risking damaged or blown speakers, and blown circuit breakers.  A high-performance dual 18 with large excursion (10mm Xmax) has a typical sensitivity of 98 dB/1W/1m.  The linear excursion capabilities of the drivers will be reached at many frequencies with an input of 1000 watts, giving an SPL of 128 dB at 1 meter.  At inputs of 2000 watts, the peak SPL will be 131 dB at 1 meter, the cone excursion at low frequencies will be reaching the damage point (very high distortion), and the response will fall rapidly below 50 Hz due to driver magnetic and suspension non-linearities and port non-linearities.  Dual 18 boxes with higher rated sensitivities either are using the peak sensitivity of the drivers at 100 Hz or higher, or are using higher sensitivity drivers, but these use shorter, lighter voice coils and suffer from reduced linear excursion capabilities, which means they start rolling off their response at even higher frequencies at high power levels, actually producing less output at 60 Hz and below!

   Even at full power, the driver in the XMAX112H is typically at less than 80% of it’s linear excursion, only reaching 100% linear excursion at 43 Hz and lower, and never exceeding the maximum mechanical excursion due to the built-in 32 Hz high-pass filter.  At 50 Hz, a high performance dual 18 at 2000 watts input will produce about 130 dB, and will be at or beyond it’s linear excursion limits.  The XMAX112H at 50 Hz and 1000 watts power will produce 131 dB and will only be using 50% of it’s excursion capability!  It should be obvious that the XMAX112H will also be lower distortion.

Architectural Specifications:

  The self-powered sub bass loudspeaker system shall incorporate one specially designed 12-inch low frequency (LF) transducer with very large excursion and power handling capabilities.

  The LF transducer shall be mounted in a folded horn with a 9-foot path length for optimum low frequency response with 101-dB/1watt/1meter sensitivity.

  System frequency response shall vary no more than +-3 dB from 41 Hz to 100 Hz (37 Hz to 100 Hz when 4 cabinets are grouped together).  The system shall be capable of producing a peak output of 133 dB SPL on axis at 1 meter.

  The loudspeaker enclosure shall be rectangular in shape.  It shall have dimensions of 22.7” W x 35.8” H x 35” D.  It shall be constructed of 15mm thickness 11-ply cross-grain laminated Baltic Birch plywood.  It shall be finished in textured black paint.

  The amplifier module shall be of high-current DCAT design and shall be capable of producing 1400 watts rms.  Input connectors shall be 3-pin XLR (pin 2=+), one for each of Left and Right inputs.  The summed mono signal shall be 4th order low pass filtered at 100Hz and high pass filtered at 32 Hz before being fed to the power amplifier and driver.  A volume control for LF level shall be provided.

  The input signal shall be fed to Full Range 3-pin XLR output connectors for connection to additional LF systems, and shall also be 4th order high-pass filtered and fed to High Pass 3-pin XLR outputs for input to higher frequency loudspeakers.

  A fan shall switch on when needed to cool the amplifier module.  Removing the rear panel shall access the amplifier module.  AC power input shall be via 3-pin IEC connector.  AC power requirements shall be 10 amps maximum at 120 volts nominal.

  The self-powered sub bass loudspeaker system shall be the ISP Technologies model XMAX112H.
