Covers
Vinyl covers for the Low B systems are now available. We’ve contracted with a leading manufacturer of
same, Tuki, to ma
ke them for us, and you can buy them directly from Acme. Standard covers are $50 for
the B
-
2, and $54 for the B
-
4. Padded covers
are $75 for the B
-
2 and $81 for the B
-
4.
Flight Cases
I am at a loss to make a recommendation. Most of the companies I have
talked to who manufacture flight
cases charge about as much for them as we charge for the speakers themselves. If at some time w
e can
locate a manufacturer who is able to offer a quality product at a fair price, we will arrange to stock them
for our custom
ers. Until then, you’re on your own. If you, as a customer, are able to share with us the
name of such a manufacturer, please do
so. I and others will be grateful.
For B
-
2 owners, it may be helpful to know that your speaker will fit perfectly into a case
made for the
older SWR Goliath system. (I’ve always admired SWR’s ability to think of catchy names for their
products.)
Cats
On
e user has reported damage from an over
-
aggressive tabby. Until you're sure your kitty isn't inclined
to use your speaker as a s
cratching post, you'd best keep the two separated.
Duct Tape
Duct tape will leave a residue on virtually
any
surface. The popul
ar carpet covering often found on
professional sound equipment, and on these Acme systems, is a particularly nasty material from
which to
remove duct tape. It is recommended that you
not
apply duct tape to your speaker. If someone puts duct
tape on your sp
eaker, common lighter fluid (Ronsonol) can be used to remove the gooey stuff.
General Information/Overview

Range System?
When I began this project, I had no idea how important the upper octaves were to the sound of the bass
guitar. I was surprised
at how bassists responded to the addition of a low
-
coloration midrange and a
tweeter capable of brilliant reproduction of high h
armonics. Modern active pickups have a very wide
-
range signal. Surprisingly, even older basses, with passive pickup systems, hav
e enough output in the
higher audio frequencies to make our little tweeter worth having. But this fact wasn’t discovered by
divine revelation, or a flash of insight on my part, it was rather a result of trying enough different
approaches to figure out
what sounded best, with a lot of help and feedback from some very patient
local bassists.
Midrange
One of the reasons the Acme
Low B speakers are three way systems is the wide variety of preferences of
bass players. Through extensive on
-
stage testing it
was found found that even among top players, some
prefer the midrange all the way up, and some like it to be virtually off. Sui
t yourself. This is an extra
adjustment parameter with which you can experiment as you perfect your sound, and it might take som
e
time for you to get used to it.
For keyboards or PA, a position of
-
5dB has worked well. This is, of course, subject to your
personal taste
and the acoustic properties of your room. It is reasonable to expect to make changes frequently if you
perform i
n very different environments. As with any new tool, you will become more skilled in its use as
you gain experience.
