| The IDMAX subwoofers combine revolutionary design philosophy with applied engineering
science achieving performance that must be experienced. They are a radical departure
from conventional design that signifies a major advancement in driver technology
and performance. The result is the first truly musical, long excursion, ultra-high
SPL subwoofer.
Even at the lowest fundamental frequencies the IDMAX effortlessly reproduces
the music faithfully with transient detail and tonal accuracy that is the result
of very low harmonic distortion. Combine the musical abilities of the IDMAX
with its ability to produce truly violent SPL levels and this subwoofers popularity
is quickly understood.
Several mechanical design difficulties had to be conquered to attain the performance
goals established for the IDMAX subwoofers.
* Keep moving mass as light as possible to MAX-imize sensitivity.
* Do not give up cone area to increase excursion, to MAX-imize volume of displacement
* MAX-imize thermal power handling to reduce power compression and MAX-imize
output at high power levels.
* Motor and Suspension design with very long linear excursion for low distortion
very high output operation.
The IDMAX conquers or MAX-imizes all of the above difficulties.
The IDMAX12 has 90.5% more linear displacement than an IDQ12 V.2 with no increase
in moving mass. This is a real feat of engineering that truly yields MAX-imum
output potential.
With our proprietary voice coil design and massive motor structure we MAX-mized
thermal power handling and reduced thermal power compression.
Massive excursion engineered in the IDMAX boasts a SPL producing 24.9 mm one-way
linear excursion (Xmax) with a 3.70" peak-to-peak (Xsus) mechanical excursion.
Larger piston area results from our unique and original surround profile allowing
the IDMAX to achieve very long excursion without reducing cone area. Since very
little of the surround of a long excursion subwoofer actually contributes to
the displacement of the subwoofer their reduced cone diameter results in lower
displacement requiring a substantial increase in linear Xmax just to equal the
displacement of the IDMAX.
To MAX-imize performance Image Dynamics has invested in tooling all of the
proprietary parts necessary. You won?t find this performance or these
parts in any other subwoofer. The parts that make this subwoofers superior performance
possible are the result of finite element analysis combined with real world
testing and product development.
The IDMAX performance is truly unique of long excursion subwoofers as they
achieve high SPL even from small amplifiers. The reason for this is the IDMAX
is like a Formula 1 Race car where advanced engineering, materials, and assembly
techniques are utilized to maximize performance. From the Structural cored composite
cone body to the high-tech voice-coil winding methods every part of the IDMAX
was engineered to be extremely strong, yet super light in weight. The low moving
mass of the IDMAX requires less suspension stiffness to balance the mass to
the compliance for proper cone control at high power levels. Lower moving mass
in a speaker results in higher efficiency because more power is being used to
create sound rather than overcome weight. Softer high compliance suspensions
also result in higher efficiency because less of your precious amplifier power
is being used to overcome the stiffness of the suspension. So even with moderate
power levels as low as 100 watts the IDMAX subwoofers will produce high output
levels and with high power levels they will produce truly explosive and violent
levels of clean undistorted sub-bass.
