Pioneer HPM-100 Bass Reflex
Speaker System
So
uncommon as to appear virtually magical are those rarefied moments in time
when the confluence of imagination, innovation, engineering genius, and
composition excellence synergistically unite to create an enduring
masterpiece—an opus which, in truth, transcends the lofty dreams,
aspirations, and ideals of its gifted composer. Thus was born into the
family of authentic audiophiles an incontrovertible classic—the
Pioneer HPM-100 Bass Reflex Speaker System. |
To the smallest detail, Bart Locanthi and his
engineering staff designed a speaker system that would optimize sonic
performance and acoustic accuracy, while the Pioneer Electronic Corporation
ensured that it would be constructed in such a manner as to maximize endurance,
reliability, and longevity. Of philosophies and commitments such as these,
classics are formed and legends are born.
“Rich Concert Realism from 100-watt 4-way, 4-speaker Bass
Reflex System with Carbon Fiber Blended Woofer & High Polymer Supertweeter”
Sheltered within the luxuriant, furniture-grade,
genuine walnut veneered cabinet beats a heart and resides a soul which, when
stirred to action, yield among the purest, the truest, the cleanest audio to
which ever ear shall be blessed to attend. Regardless of the melodic genre to
which one's individual predilections or tempers may tend, the
Pioneer HPM-100 Bass Reflex Speaker System will,
with an effect nearing perfection, render rapt, nay, spellbound the listener.

“Bart Locanthi's Vision & Genuis — Pioneer's
Dedication & Commitment” |
*It was the Pioneer Electronic Corporation
that in June 1962 introduced the world's first component stereo system.
*In order to increase sensitivity while
minimizing extraneous vibrations, the woofer, midrange, and tweeter
incorporate solid, cast aluminum baskets vice the cheaper, stamped steel
baskets that are contained within the majority of speaker systems. |
*Chemically treated, pleated fabric, speaker
surrounds (annuli) assure stable underpinning, precision dampening, and
extraordinary longevity as opposed to the common foam (disintegrates quickly;
short-lived; cheap) surrounds which have received and continue to enjoy
widespread usage.
*Incisively designed, heavy wooden enclosures
(long the favorite environment of premium grade speaker systems) yield
superior quality, professional monitor audio performance— exceedingly tight,
deep, dynamic, well-articulated bass (bass reflex system); a beautifully
balanced, open, natural midrange; and uncompromisingly accurate,
well-defined, transparent, airy highs. |

*The carbon fiber (which, as a result of its
unparalleled strength to weight ratio, is employed extensively in the
construction of military aircraft) woofer provides the durability, rigidity,
and light weight essential to produce a bass that is not only capable, when
adequately powered, of destroying the tympanic membranes of an entire
neighborhood, but to reproduce subtly and accurately, to separate, and to
distinguish between delicate orchestration and soft, subdued vocals.
“Music proposes. Sound disposes.”
—Babette Deutsch (1895–1982), U.S. poet.
“Electronic Concert,” line 1 (1969).
In order to facilitate your research of the
Pioneer HPM-100 Bass Reflex Speaker System and the man whose vision and
genius made them possible, we highly recommend that you read the comments of
those audiophiles who possess far more expertise, knowledge, and experience
than do we. Therefore, we are pleased to provide the following links: |
Connecting Speakers to Amplifier
Connect RED (+)
terminal of the HPM-100 to the (+) output of the amplifier, and the
BLACK (—) terminal to the (—) output terminal of the
amplifier. To connect each lead wire, strip 3/4" (20mm) of insulation from the
end, press the appropriate terminal button and insert the wire.
Level Controls
Individual controls are provided for the
MID and HIGH frequency
ranges, and when set at "0" a suggested output characteristic is obtained.
Turning either control clockwise increases the output from that speaker, while
turning fully counterclockwise reduces the output signal to zero.
General Precautions
- Before connecting the speakers, turn the amplifier
POWER switch OFF.
- Take care to maintain correct polarity (See Connecting Instructions).
Incorrect polarity destroys the stereo effect and severely reduces the low
frequency response.
- Use high quality wire: #20 gage wire may be used for distances up to 40
feet. For greater distances use heavier gage wire.
- The maximum input power of the HPM-100 is 100 watts. Excess input power
may damage speakers or cause unusual noise.
- Do not touch any part of the speaker cones.
- The nominal impedance of the HPM-100 is 8 ohms. Speakers may thus be
combined with an amplifier whose output terminal impedance is 4 to 16 ohms.
- The enclosure has a fine finish. Polish the enclosure periodically with a
polishing cloth or a soft dry cloth together with furniture wax. For maximum
surface protection, do not use chemicals such as insecticides or volatiles.
“Music has charms to soothe a savage breast,
To soften rocks, or bend a knotted oak.”
—William Congreve (1670–1729), British dramatist.
Almeria, in The Mourning Bride, act 1, sc. 1 (1697).
“It was, indeed, the pre-dawn of a new and
illustrious Golden Age of Music, yet a great darkness of thin, tinny highs;
muddy, shallow basses; malformed, misrepresented mid-ranges; and craggy,
craterous crossovers lay upon the ears of the increasingly frustrated,
discontented, and disenfranchised audiophiles who sought the one, the true grail
of speaker systems. Whilst there existed many pretenders to the throne, there
could be but one rightful King; one who could, with absolute fidelity, draw
forth from the Cone of Distortion the resplendent Acoustics of Accuracy.
Raged within the consecrated palisades of
the Castle of Capitalism a contentious conflict between the Knights of
Management, the Knights of Marketing, and the Knights of Engineering. These
hallowed halls of commerce bore witness to many such battles, for atop their
ivory towers and crystalline ramparts fluttered disdainfully the banners of Net
Profit Margins, Sales Numbers, Stock Valuation, and Price versus Performance—
while somewhere, unseen and unadorned, deep
within the castle's darkest recesses, hung limp the tattered streamers of
State-of-the-Art Technology and Design. Such were the sacred rites and rituals.
Such were the archetypal inevitabilities when such campaigns were pressed.
Though highly revered and venerated as
"Purists of the Realm," the Knights of Engineering were possessed of neither
power nor influence. Seekers of truth, excellence, accuracy, and honesty, they
were men of high ideals who, above all things, loathed bad science and
compromise. While stooped and faded from the inescapable concessions to and
dictates from those who dwelt within the rarefied environs of the ivy veiled
walls and who donned the regalia of the MBA, they vowed that this time they
would stand fast—this time they would, if but this once, achieve victory. For,
you see, a sage of great renown had joined their ranks; no mere knight this one,
but a Prince both wise and highly decorated; a battle-scarred champion in whose
veins coursed the blood of audio royalty and aside whom they would wage this
final crusade.
Taking up the gauntlet of the audiophiles
and drawing forth the Acoustics of Accuracy, Sir Bart Locanthi courageously
strode forth into the midst of that cacophony of impostors whose maze of
mediocrity had long prevailed.
Alas, we may know little of the struggle
which ensued, for whilst history tantalizes us with mere morsels, we crave the
full feast. This much, however, we may know and long remember: Sir Bart emerged
victorious that day, and thus was rightly crowned the true King—the
Pioneer HPM-100.”
