The Diamond Audio ProMedia 2012 Speakers
the MidiLand S2 4100? Diamond Audio engineered and produced that line of speakers
for MidiLand. Great sound, great price point. Now, DA (not to be confused
with Diamond of video card fame) has amicably severed their ties with MidiLand
in favor of going it alone. The 2012 represents their midrange model of the
ProMedia lineup. This is the second review in a series of three, the 2010
will follow shortly. For now, let's have a listen to their best single driver
setup, the 2012.

This is your
typical ported single driver design rig. What's slightly different from the
norm is DA's top mounted 3" full range driver and sloped back cabinet.
This is a good idea as many other designs of this genre have their only driver
pointed forward perpendicular to your desk or table. High frequency reproduction
and overall clarity should be improved dramatically.
The AC adapter
is only a moderate size and must be plugged directly into the last position
of the power strip (if you use one) otherwise, the cord will block at least
one other precious AC port. As you can see from the pictures on another page,
the unit is rated at 15VAC @ 1.1A, which is 16.5VA.
button is located on the right speaker. It has the typical "click"
to turn on and twist for volume increase. The bass and treble controls are
also the typical center detent kind. Twist left decreases treble or bass and
twisting right increases the very same. Below the bass knob is DA's 3DSP(TM)
button, which when pushed supposedly gives the two speaker setup a pseudo
"3D" effect. Lastly, for those users that require a conveniently
located headphone jack, the 2012's have one just above the green LED power
of the right speaker sports the expected left speaker RCA output, AC input
(from the wall wart) and stereo mini-jack input (from the output of the soundcard).
What struck me as odd was the available sub-woofer output. I remember seeing
these years ago on many other units, but due to price drops and lack of stand
alone subs, I question their use today. Even DA doesn't sell a matching woofer,
so you'd have to look elsewhere to find one if just had to have one.
department makes specific mention that their products are not rated with the
fake and largely untestable PMPO (peak music power output) specification.
When they claim X watts per channel, they really mean it! Considering that
I tested basically met DA's power claims, I was eager to put the SGS-Thompson
TDA2007A amplifier chip to the test with the 16.5VA wart.
and reported of this type is done without any opinion or bias whatsoever.

The satellite specs are
not specified by the manufacturer. They looked similar to the 3025's 3"
unit, but DA informs me that they are different. Driver tests and listening
tests confirm that the differences are for the better.
Affecting power measurements,
and thusly power ratings, the satellite impedance is near to 4 Ohms but I'd
have to assign a number closer to 5½ Ohms for the purposes of power
