Hello All:
As some of you may remember, there was a development effort undertaken some
time ago to produce a companion external speaker for the K2. Unfortunately
the prototype -- dubbed the SP2 -- will not make it into production.
However, I have compiled a 12-page article that describes the more critical
construction details of the project for those who might want to duplicate
the effort and produce their own version. The article contains over 20
photos, several construction diagrams, performance curves, a schematic, and
a parts list.
In brief, the SP2 uses a readily available front-firing 4" speaker mounted
in an EC-2 enclosure to achieve superior sound quality over the stock K2. A
small amplifier (with low pass and mute circuits) is included to increase
the available audio drive from the K2.
If you drop me an e-mail (off the reflector), I'll be happy to forward a
copy of the article to you (PDF file under 500Kb in size).
I will also be selling the prototype pictured in the article. You can
contact me directly if you are interested in it. The price would be $150.00
USD plus shipping.
Regards
Dave
