Plans

??? 2000

Try different back chambers for the Morel tweeter.

Summer 2000

First prototype cross-over design.
After I buy a house and can do some real mid-range measurements.

Present

March 2000

So far I have only done some computer simulation of crossovers.
I really want better measurements than I can perform in my
living room.
I’m thinking that will have to wait for owning a house, which I
hope to be doing sooner rather than later.

January 2000

The mid-range resonance at 1 kHz looks like a cone resonance,
coating the driver basket with bondo didn’t do a think
except make a mess of a couple of drivers.

August 1999

Mid-range testing.
I noticed what looks to be approximately a 1 kHz resonance during early
mid-range tests.
My guess is that this is from the driver basket resonating.
It may be possible to reduce the resonance by coating the basket with
a thick layer of bondo or other material.

July 1999

The mid-range positioning tests were quite a surprise.
I did not anticipate any of the results.
Using the results, I have built a third prototype cabinet.
The basic driver measurements look good, so its time
for port tuning and crossover design.

Past

February 1999

The diffraction tests were basically null results.
I did learn that the mid-range position on the baffle may affect
the tweeter’s response.
The next series of tests will be to determine a good mid-range position
relative to the tweeter.

January 1999

Tried different cabinet types and front baffle dimensions.

July 1998

First prototype cabinet completed.
