Woofer Enclosure
The design goal for the woofer enclosure is:
(1) To be as resonance free as possible (rigid) to prevent
low frequency and mid-range colorations.
(2) To provide sufficient internal volume to give the
desired frequency response.
(3) To visually appear smaller than it is when attached to
the rest of the speaker.
Research has shown that even if the resonance levels of an enclosure are 40 or more
dB below the signal levels of the woofer, they will still be audible because their
harmonic structure is almost always different than that of the signal coming from the
woofer itself. In order for the woofer to successfully blend with a planar mid-range
driver, it must be very neutral.
Eminent Technology engineers have a great deal of experience performing mode
shape analysis using instrumentation on many different structures. The experience
gained from this research was put into the design of the woofer enclosure. The shape
of the enclosure results in only two of the six sides having the same shape. This
means that the fundamental resonance of one side of the enclosure will not excite a
different fundamental resonance of another side. The enclosure is internally braced
with a total of five internal braces. The largest brace crosses the center of the box.
Four other braces break up modes on the back and front surfaces. The box is
constructed of a high-density particleboard and is then laminated.
