IN THE LAST 24 MONTHS 11 COMPANIES HAVE INTRODUCED "SUPER AMPLIFIERS" THAT YOU CAN'T FULLY APPRECIATE UNTIL YOU HEAR THEM THROUGH THESE SPEAKERS.
INTRODUCING HPM-200.THE FIRST SPEAKERS DESIGNED TO DELIVER ALL THE SOUND EXPENSIVE,HIGH-POWER AMPLIFIERS CAN PRODUCE.
Most speakers available today were designed at a time when most of the powerful amplifiers you could buy produced under 100 watts a channel.
Which means if you have invested in one of the new super amplifiers, your speakers could well be keeping you from appreciating the full extent of your investment.
So Pioneer has developed a speaker system that can bring you all the peak levels, all the transients, every last bit of listening enjoyment your super amplifier is capable of giving you.
It's called HPM7200. "HPM" stands for "High Polymer Molecular" film, a material that makes it possible to transform electrical energy into acoustical energy with complete accuracy.
The HPM-200 tweeter and supertweeter are made of this unique material, which produces sound directly at the film surface.
There are no magnets. And no voice coils. So there are no mechanical moving parts to get between the sound your amplifier puts out and the sound you hear.
And High Polymer Molecular film can handle an almost limitless range of power. Without distortion. Without any loss in linear response.
--------The revolutionary High Polymer Molecular film tweeter and supertweeter.
They don't look, or work like conventional speakers.
[…]
…driver.
A 2.5” neoprene-impregnated cloth dome unit that, unlike most speakers, is peripherally driven for low distortion. Also unlike most speakers, this midrange unit is accurate to within 3 dB. even at 60° off axis.
And, to keep all five HPM-200 drivers in balance and working together, we've engineered a massive crossover network that keeps all sound waves in phase over the entire listening area.
--- High Polymer Molecular film produces sound directly on the surface. So
there's no need for voice coils or magnets.
But no design dissertation can fully describe High Polymer Molecular what the HPM-200 actually sounds like. So there's no need for ye voice coils or magnets.
Irving Kolodin wrote for Saturday Review, after hearing Berlioz' “Symphonie Fantastique " over a pair of HPM-200s … "... such towering presence that one could diagram the disposition of the Chicago Symphony just from the reproduced sound”.
We believe the HPM-200 represents a new standard of accuracy in loudspeakers. Its dynamic range, transparency and overall lifelike impact are without precedent.
Ask your Pioneer dealer to play the super amplifier of your choice through speakers similar to the ones you're now using.
Then ask him to play it through HPM-200s.
We assure you, you'll hear things you've never heard before. Hpm. PIONEER U.S. Pioneer Electronics Corp., 75 Oxford Drive, Moonachie, New Jersey 07074.
