Providing subwoofer design software programs for
solving the required calculations for custom bandpass, sealed
and vented box cabinet designs. Can be used for car, truck,
sport utility vehicle (SUV), jeep automotive, guitar and home
theater applications and projects. This site provides the
instructions and "how to" information to successfully plan,
design, construct, build and setup subwoofer enclosure systems
using AJ Bandpass Designer, Sealed Designer and Vented
Designer. Works with any type and size of driver (8, 10,
12, 15 inch). The Subwoofer Designer Series is intended for
the hobbyist, audio / acoustic enthusiast and Do It Yourself
(DIY) speaker builder.
Bandpass Designer, Sealed
Designer and Vented Designer provide accurate theoretical
solutions for subwoofer driver characteristics and attributes
(Thiele Small) and box/enclosure parameters with an easy to
use interface. There exists other calculations, not
included in the software, because they are not required
and provide little technical information.
As with any
design or engineering of speaker enclosures, the performance,
sound output, bass, and sub frequencies are not
guaranteed. Band pass, Sealed and Vented Designer
calculate speaker parameters based on loudspeaker theory and
engineering equations/principles/formulas. The
calculations are used to predict loudspeaker parameters. This
was noted, because not every loud speaker design will give the
expected results. |
