The control panel of the powered FBT Maxx speakers shows the features (some exclusive to FBT Maxx speakers) that you can SEE and TOUCH.
But, WHAT’S UNDER HOOD really matters in reproduction of Superior Sound Quality and Long Term Reliability.
The FBT Maxx Hidden Features
a) FBT’s Polypropylene Cabinets: FBT Maxx, Jolly, and Amico Polypropylene cabinets are produced
using a “Gas Injection Molding Process”. Another FBT exclusive! This Gas injection molding process
produces a structurally superior polypropylene cabinet with a denser molecule structure that is sturdy,
but yet forgiving against bumps and rough handling, but without flexing. The Gas Injected Molded
polypropylene cabinet sounds more like a wood construction speaker cab with robust LF response. All
other manufacturers of Polypropylene Cabinet speakers use an Air Injected or Roto molding process
that does not produce a cabinet with the sonic quality of a Gas Injected Molding Process molded
cabinet. FBT Polypropylene cabinets also have a Honeycomb shaped cabinet interior to make the
cabinet extra sturdy. FBT poly cabs have seams where of the 2 pcs. (front and rear) cabinet mate, where
a rubber gasket is placed to produce a weather resistant tight seal to keep the cabinet from water /liquid
damage and a form an expansion joint to prevent cabinet cracking, etc. due to rough handling or rapid
temperature charges.

b) Studio Quality
Foam Lined
Cabinets: a FBT
Exclusive. Again,
under the hood, all
FBT Polypropylene
Cabinets are foamed
lined to prevent
unwanted sonic
resonance from
backpressures from
the speakers.
Along with the Gas Injected
Cabinets, this foam lining helps
produce the sound quality of a
wood construction speaker. The
sonic quality of FBT speaker cabs
overcome the objections from some
people that plastic speaker cabs:
sound like plastic with
overcompensated midrange and
not having very good low frequency
reproduction in comparison to
plywood constructed speaker cabs.
c) B&C® Woofers and High Frequency Drivers – FBT uses B&C speaker components. Since 1946 all B&C Speakers have been produced in Italy using the finest
quality materials. Woofers with Aluminum Die Cast Frames, Neodymium Magnet Structures, Kapton voice coils wound with 99.98% Oxygen Free Copper Wire, High Quality
Paper Cones and Quality Adhesives. HF drivers with Neodymium Magnet structures, Titanium Diaphrams and where applicable high density Mylar Diaphrams as used in
many high end home Stereo HF Tweeters.
d) FBT Circuitry: The electronic
components under the hood that makes
up the power amp circuitry in FBT
Power amplification are of the Best
Quality Name Brand Components
available. Texas Instrument, Fairchild,
Elna, Alps potentiometers, Motorola,
along with European manufactured
transformers and other Surface Mounted
Technology electronics with tight
tolerances (1-5%) Military Spec are
utilized in the amp module circuitry
placed on double flooded Mil Spec
Circuit boards.

Period.
Many Competitors like type models and the many cheap Asian produced knock offs use cheap electronic parts with tolerances of 15%- 25%. What this means is that as the
product ages, the excellent factory specs listed on their spec sheets when the product is Brand New, will being to vary as much as 15%-25%! The sound quality deteriorates,
the power amp output rating goes down, and the electronic parts that make up the circuitry tend to fail that much quicker!
Unlike many Competitors models with all of the circuitry placed on 1 circuit board (the power supply, the preamp control circuitry, and the EQ filter circuitry) on a SINGLE
CIRCUIT BOARD, which is much cheaper to produce and assemble. But, by placing all of the Circuitry on ONE circuit board, if a critical electronic component fails in the
power supply section or preamp section, these shorted out parts can pass DC Current along to the other stages of the circuitry, mainly the power amp section resulting in a
completely unrepairable circuit board. You have to junk the whole preamp and power amp circuit, which leads to a very expensive total board replacement.
The FBT Maxx Series powered speakers use MODULAR circuit board construction with independent circuit boards for each stage of the Amp. This modular circuitry
construction uses independent circuit protection in Preamp circuit stage, EQ filter stage, and Main Power amp circuit board, so complete total circuitry failures are 99.9%
eliminated. If an independent circuit fails, the failures are limited to just that circuit.
e) Built in EMI/RFI - AC Power
Conditioner Filter Circuitry: All FBT
Powered Speakers, mixers, power amps
have built in EMI (Electrical Magnetic
Interference) and RFI (Radio Frequency
Interference) circuitry, somewhat similar
to a good quality power conditioner. This
EMI/RFI circuit helps to protect the FBT
product from AC hums and other electric
co. power shortcomings and Radio Wave
Interference from broadcasters, taxi cabs,
cell phones, and wireless microphones
transmissions.
