Do-It-Yourself products
The following is a list of DIY products that you can
purchase. Follow the links for further details and ordering information.
LX521 Construction Kit
$300
ORION Construction Kit
$240
All the information to build a world-class speaker is provided. It is a 3-way
active system. Two ASP circuit boards are included for assembling the
Crossover/Equalizer and a ORION Test Signal CD for testing the electronics and
the speakers. The completed speakers cost around $3700, without power amplifiers.
Optional products at additional cost:
Assembled and tested
Crossover/Equalizer from Wood Artistry
6 x 180W AT1806 power
amplifier $1850
12 x 60W AT6012 power
amplifier $1950
ORION Cabinet
Kits $1400+
Precut, highest-grade Baltic Birch Plywood parts for easy assembly of the ORION
speaker cabinets.
ORION Revision 0.1
$250
A revised midrange driver mounting scheme and easy to apply Conversion Kit.
PLUTO Construction Plans+
$190
A 2-way active loudspeaker with built-in power amplifiers for near-field
listening. Its small footprint and light weight allow it to be used with optimum
placement in any room. Sonically it is a close match to the ORION, except
for the lowest frequencies.
PLUTO+ subwoofer
$100
Using two w-ASP printed circuit boards for adding subwoofers to PLUTO makes it a
3-way system and a worthy alternative to the ORION.
PHOENIX Construction Plans+
$240
A 3-way active speaker system with separate dipole woofers and MTM open baffle
panels. A forerunner of the ORION and with a total output volume capability that
exceeds what is tolerated in most home environments. Two ORION ASP circuit boards for assembling the
Crossover/Equalizer are included with the documentation.
(Sufficient information for building the PHOENIX or designing a dipole
speaker can be found on the Website CD, without purchasing the PHOENIX Construction
Plans+, if you are experienced in active filter design.)
THOR Construction Plans+
$160
A closed box subwoofer for addition to an existing speaker system. The
documentation gives specific information for adding THOR to the ORION and is
meant for Home Theater applications. Two w-ASP circuit boards are
included with the documentation.
(Sufficient information for building the THOR or designing a closed box
woofer can be found on the Website CD, without purchasing the THOR Construction
Plans+, if you are experienced in active filter design.)
ASP printed circuit board set
(2) $150
A general Analog Signal Processor topology for designing and building 2-way or
3-way active loudspeakers, for closed box or open baffle. Two ORION ASP circuit
boards are included. The documentation provides only the ASP block diagram,
component layout, and circuit
topology. The actual circuit components need to be determined by the user. The
ASP is targeted for advanced speaker builders with the necessary familiarity of
electronic design.
w-ASP printed circuit board
$50
A specialized Analog Signal Processor topology for adding a woofer to a midrange
or a subwoofer to an existing loudspeaker system. The documentation provides only the
w-ASP circuit diagram,
component layout, and material list for PLUTO+. The actual circuit components
for a different application need to be determined by the user. The w-ASP is targeted for advanced speaker builders with the necessary familiarity of
electronic design.
MT1 printed circuit board
$40
The circuit topology allows the design of 2-way speakers with crossovers of up
to 24 dB/oct slope. Delay circuitry to compensate for tweeter offset, and for
baffle diffraction, is provided. The pcb is ideally suited for a 1st time active
loudspeaker project. A single MT1 pcb has left and right channels.
WM1 printed circuit board
$30
The circuit topology allows the design of dipole equalizers and the 'Linkwitz
Transform' biquad. It is used for closed box or dipole woofer equalization. It
has a notch filter for room or speaker equalization. In conjunction with the MT1
pcb it allows the design implementation of full-range 2-way speakers. A single
WM1 pcb has left and right channels.
Toneburst Test Signal CD
$20
Special test signals for evaluating the low frequency accuracy of your room and
loudspeaker combination.
Demo CD $20
Demonstrate the capabilities of your loudspeakers with samples of my own recordings.
I have used them to evaluate the reproduction accuracy of my speaker designs.
