To state the obvious, deep bass is
fundamental to realistic sound reproduction.
Music and movies alike depend heavily on
the lowest octaves of human hearing to
communicate the power, impact, and “you-are-
there” excitement of the sonic experience.
But your hearing can’t respond to what isn’t
present, and reproducing true deep bass
accurately, dynamically, and musically is no small
matter. Neither is doing so from a conventionally
engineered ultra-compact subwoofer. In fact, it
borders on the impossible.
Fortunately, PSB is no conventional company. For three decades and more
PSB has been creating innovative, high-performance, high-value solutions to
the challenges of sound reproduction. Company founder Paul Barton and the
PSB team are internationally known for leading fundamental research into
loudspeakers, room acoustics, listener response, and the interactions among
them. Consequently, PSB’s cumulative knowledge-base on the workings of
sound reproduction is an unequalled resource, one that uniquely positions
PSB to create loudspeakers and subwoofers that work optimally under real-
world conditions to fulfi ll the needs of real-world customers.
By declining, as always, to accept standard-
practice design norms as immutable rules, the
talented PSB engineering team has created
the PSB HD
8
and HD
10
to provide astonishing
deep bass, high output performance from cubes
measuring only
10-1/2
” and
12
” respectively.
The Challenge
The challenge of subwoofer design can be
summed up quite simply yet completely as
follows. “Small, deep, loud: pick two.” Achieving
all three goals from a single design package
– with PSB’s legendary musicality – is on the face of things an impossible
task, one that requires overturning, or at least overpowering, the laws of
physics. PSB’s HD
8
and HD
10
do so with a singular combination of brute
force and engineering fi nesse.
Frankly, the brute force was the easy part. The HD
8
and HD
10
employ
sophisticated Class H amplifi ers that produce 500 and 750 watts of
continuous power respectively (and some 1,600 and 2,000 watts of peak
dynamic potential) allied with PSB’s “smart bass” monitoring system to
preserve accurate musicality at even the highest volumes and lowest
frequencies. Equally important, they do so from electronics smaller in size
