FBT HIMaxX 100 SA Processed Band-pass Active Subwoofer

With the new HiMaxX series, FBT establishes a reference point on the scenario of 12” and 15” enclosures in polypropylene for sound reinforcement, introducing performance and technical content of a standard unthinkable up until now. FBT HiMaxX takes its place alongside the FBTMaxX series, exalting all the technical features.

The study of a new cabinet in polypropylene, the use of a switch mode power supply and high efficiency power amplifiers and the redesign of the loudspeakers were the activities of the FBT R&D team aimed at maximizing the power weight ratio.

This series comprises three models; two 2-way full-range enclosures in polypropylene, HiMaxX 40(12”+1”) and HiMaxX 60 (15’’+1.4”), plus a compact  18’’ bandpass SUB in birch plywood (HiMaxX 100Sa).

Compact and light weight, HiMaxX brilliantly solve all the most demanding requests from buffs, musicians and professionals looking for powerful, versatile and very high quality loudspeaker enclosures. Ideal for live and sound reinforcement applications requiring ease of transport, they are also suited to fixed installations, thanks to the cabinets’ format and optional accessories. 

• Self-powered bandpass subwoofer
• 18” (460 mm) custom neodymium B&C woofer with a 3” (75 mm) voice coil
• Built-in 900Wrms PWM amplifier
• Switch mode power supply
• Analogue signal processor with limiter
• Control panel with:
• XLR/input and XLR stereo outputs with Hi-Pass, filter for connecting the satellites
• Volume
• Ground-Lift
• 0°-180° phase inverter switch
• Limiter LED
  • Box in 18 mm (0.7”) birch plywood
  • The special “bandpass” acoustic loading increases efficiency and maximum SPL
  • Eight M10 mounting points, stand socket and two integrated wooden handles.
  • Optional 4 swivel-mount casters 80 mm ø (3.15”) on request.

• A powerful dynamic design for aggressive clean-cut lines.  A sturdy light-weight box that ensures great versatility and is ready for installation, thanks to its special mounting points and optional accessories. The asymmetrical design enables the enclosures to be used as stage monitors.
• A specially designed control panel ensures ease of use and intuitive control. Mic/line input, auxiliary stereo input with (HiMaxX 40a), 3-band EQ, ground-lift, diagnostic LED.
• Loudspeaker totally redesigned in collaboration with B&C. FBT studied and designed a special chassis, a more efficient ventilation circuit with a consequent reduction of 2dB “power compression”, a considerably stiffer coneto improve reliability and distortion and an even more powerful neodymium magnet to increase control and efficiency. The voice coil has a diameter of 75 mm (3”) for higher power handling and reliability.
• B&C compression driver with a 25 mm (1’’) throat and 44 mm (1.7’’) coil (HiMaxX 40) for high power handling. Thanks to the use of a shorting copper cap, high frequencies are even more dynamic and crystal-clear.
• The development of the innovative amplifier is the result of years of research by the FBT R&D labs. It manages to combine the contrasting features of lightness, high power, efficiency and reliability, using the very latest technology. A switch mode power supply to reduce the weight and increase the power output velocity, a very high performance PWM amplifier for the low frequencies, to maximize the power fed out with minimum heat dissipation. A Class G amplifier for the high frequencies enables to achieve the audio quality of a Class A, with a much higher output.
• The silent preamplifier manufactured with SMD technology has the job of handling the equalization, 24dB/oct  crossover, sophisticated protections, limiter and the commands of the control panel.
• The horn’s profile has been redesigned to ensure greater directivity control and lower distortion. The dispersion angle is 90°H x 60°V.
• Research work carried out with the university on the cabinet’s resonance and the fl uid dynamics of the air led to the manufacture of a box in polypropylene with injection of absolutely inert GAS and efficient reflex ducts free from undesired turbulence.
