the end was quite successful.)
other changes which distinguish the Low B Series II from the original? Several things.
The distinctive metal edges which gave
our speakers such a conspicuous appearance were considered
important in the early days of the company because, frankly, we were
trying to be noticed. This isn’t a
concern any more. In fact, we have heard of TV producers who actually balk at the idea of hav

After we upgraded the bare metal screens to a powder
coated finished version, i

es II models have a new charcoal black powder
coated steel edge protector. Better.
The original Low B crossovers had a design d

Not any more, however. We found a way to add a component to the crossover which actual

the attenuators. The trade

which is equal to 99% power

Another change which has been made to the crossover is that instead of being su

Handles. I’ve been internationally cond
emned and universally chastised for my choice of small, recessed
handles for the Low B systems, particularly in the case of the
4 unit. (See section on Handles later
in this publication.) I know when I’m licked. I admit that the handles I’ve used o
useless, other than providing internal support for the ports, and I’ve caved in to popular demand
4 Series II now has larger, heavier, and more useful handles. It’s the best example of this type of
to find, and they aren’t cheap. The B

mounted port. More on this below.
