Introducing the Series II Models
Since the int
roduction of the original Acme Low B
-
2 in December 1993, and the Low B
-
4 in September
1994, the speakers have remained unchanged
until now, with the exception of a rust
-
proof powder
coating on the front grilles. The original period of development of these
two models was long and
painstaking, and I believed at the time of their introduction that nothing could be done to improve them
.
In the ensuing years, with the distribution of the speakers all over the United States and six continents (no
customers in An
tarctica yet), we have had the opportunity to receive comments and feedback from a very
diverse group of individuals. Most of th
e suggestions had been anticipated during the design process, and
weren’t particularly helpful. Some advice has been valuable, h
owever, and was filed away until such a
time as a number of small improvements could be incorporated into a different enough spe
aker to justify
a new designation: “Series II.”
The incorporation of these changes has been concurrent with the development of
our new Low B
-
1 1x10”
model, which is being introduced as part of the “Series II” line, even though no previous 1x10”model
existed.
One other reason these several small changes have been “saved up” for their simultaneous introduction
into a design wh
ich I believed to be essentially perfect years ago is that the manufacturer of our little
tweeter, Audax, actually discontinued
this marvel of high
output and cost effectiveness in mid 1996, shortly before
Scott Malandrone, of “Bass Player” magazine discov
ered
our products and introduced them to the bass playing
world in the November 1996 issue.
After the review in BP was publishe
d, we scrambled for
tweeters, and bought every one we could find in the
United States and Canada. A sizable pile of tweeters it
was. But not any more. We’ve used them up.
Interestingly, after examining a great many tweeters
from a great many manufacturers
since then, we were reaching a point of total frustration when,
viola
, in
mid 1998 we were able to examine samples of the lates
t high
-
sensitivity models from, you guessed it,
Audax.
They say the fruit doesn’t fall far from the tree, and in this case they
are right
-
our new tweeter of choice is
the model from Audax which superseded our beloved shallow horn. The new model is a slig
htly deeper
horn. It has a larger voice coil, a rare
-
earth neodymium magnet, handles more power, and in fact,
exhibits slightly
less coloration, and better projection than our original tweeter, which was quite good.
Like it’s predecessor, it is a marvel
of high output in a tiny package. Unfortunately, it’s a little more
expensive, but it sounds better too, so that’s OK.
(The in
corporation of this new tweeter into an existing design is what made development of the 1x10”
model take so long. It required an
enormous computer model to “exactly” duplicate the response of the
