New Loudspeaker
Design: Auspice Project Simply follow the above link
to the Auspice Project. In
search of 110db with minimal power compression and cost
effectiveness... Here is the design for my
"DIY" Argonaut Prestige loudspeaker. It is a
medium sized bookself speaker featuring a 6.5" inch
polypropylene cone woofer and a 1" aluminum dome
tweeter. Two versions exist. The first features a sealed
box and has a corresponding high F3 of 110 hz. It is
suitable for use with a powered or passive subwoofer to
supply deep bass. The second is a vented enclosure which
has an F3 of 60 hz. In this for it is suitable for use in
smaller rooms as a mini-monitor style louspeaker. Both
versions sport the following features...
- Optimized Acoustic 3rd order crossover at 2,000
hz.
- Diffraction Loss and Room Effect Compensation
- 1:1.68 horizontal placement for smoother response
- Good dispersion in the 0 to 18 degree vertical
range (around 2000 hz)

- Woofer's 4mm xmax offers low compression
- A large woofer maximum excursion of 20mm (full
stroke)
- Power handling in excess of 100 watts
- Sensitivity: 87 db/2.83V (1M)
