SUBWOOFER

The equipmenT

Atlantic Technology’s 334SB is the second-

smallest subwoofer in its ‘SB’ range. It and

the model below it (the 224SB) have 254mm-

diameter bass drivers, while the two models

above it, the 444SB and 642e (and no, I don’t

know who dreamed up those model num-

bers!) sport 305mm-diameter bass drivers. All

models have internal power ampliﬁers whose

outputs increase in steps from a claimed 180-

watts for the 224SB to 350-watts for the 642e.

While it’s not immediately obvious from our

photograph, the 334SB’s enclosure is totally

sealed. This means that there’s no bass reﬂex

port, so there’s no possibility of unwanted

‘chufﬁng’ (noises from the port caused by air

moving in and out) and also no possibility of

small creatures (I recently heard of a pygmy

possum having to be removed from a Para-

digm speaker) making their home inside your

subwoofer. The trapped air inside the cabinet

also acts as a ‘cushion’ that helps protect the

cone from being overdriven.

ubwoofers have come a long way

in many ways. One of the most sig-

niﬁcant is that it’s not that long ago

that I’d often have to explain what a

subwoofer actually was to most people. These

days, thanks to the over-whelming accept-

ance of multi-channel home theatre systems

and the enthusiasm with which movie

producers make sure there’s plenty of low-

frequency information pumped into the sub-

woofer (0.1 or LFE) channel, subwoofers have

become part of the consumer lexicon. So

most now not only know what a subwoofer

is, they’re happy to have one in their home.

At the same time, subwoofers now perform

better than they ever have. The advent of

low-cost, high-power Class-D ampliﬁers has

meant that subwoofer designers ﬁnally have

all the ampliﬁer power they need at their

disposal at a reasonable cost, making it pos-

sible for small bass drivers, in relatively small

cabinets, to deliver impressively loud—and

impressively low—bass at affordable prices.

The bass driver is front-ﬁring and,

although it’s rated by Atlantic Technology

with a diameter of 254mm, that’s actually

the overall diameter of the entire basket.

The more-important Thiele/Small diameter

is 210mm, which gives an effective cone

area (Sd) of 346cm². The cone is made from

paper, as is the dished central dust cap. The

surround suspension is rubber. Powering the

cone is a 50mm-diameter aluminum voice

coil, around which is wound four layers of

copper coated aluminium wire that operates

in the gap of a large centre-vented magnet.

The back plate of the Atlantic Technology

is fairly bare, not least because it has only

line-level inputs, not both line-level and

speaker level. Similarly, there are only line-

level outputs. The low-pass crossover control

is continuous, via a small plastic rotary knob,

and is marked ‘40Hz’ at its lowest point, and

‘140Hz’ at its highest. Alongside it is a ‘cross-

over bypass’ switch that actually looks like

a bit of an afterthought, because additional
