What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Jensen Optimum Performance Concept


Many years ago, Jensen sound engineers went to work on a whole new concept in speaker design, OPC , the Optimum Performance Concept. It was based on one simple idea. That each part of a speaker system should be designed to help reproduce sound the way it was recorded. The same highs and lows. The same midranges. In all directions.
After five years of development, this concept has become a reality with Jensen's all-new OPC high fidelity line. It's been a long wait. But when you hear them, you'll know it's been worth it.

OPC means distortion-free bass response
Other speaker manufactures use cloth to connect the outer edge of a speaker cone to the speaker frame. We use exclusive Flexair foam suspension on every OPC speaker system for less restricted cone movement.

OPC means truer midranges
OPC speaker systems come with tuned isolation chambers. They're specially designed to smooth out midrange response and eliminate distortion resulting from mingling of frequencies in the speaker cabinet.

OPC means improved high frequency response
Our unique Sonodome tweeter disperses sound at a wide 170° angle to fill a room with brilliant highs… highs you're not used to hearing in home speakers of comparable price.

OPC  means functional design features
A specially designed bronzed-tinted dust cover shields and protects the optimum performance conrols. It is easily removed for ready access to the control panel and locks quickly back into place.
OPC means sound control
Not everyone likes to hear sound the same way. That's why we put optimum performance controls on the front of every OPC speaker system. These allow you to adjust the volume of bass, mid-range and hih frequencies without altering the sound itself. Each control is color keyed to speaker system components for esy reference (blue/bass; yellow/midrange; red/high frequency).


OPC means greater driving force
Instead of the metal magnets used by many other speaker manufacturers, we used super-powerful Syntox-6 magnets for greater activation of voice coils.
OPC means longer life
We're so pround of the way we built thase new jensens that we offer a full 5 year warranty. If anything goes wrong with your jensen OPC speaker, we'll fix it free of charge (including parts, labor and all shipping costs)
OPC means improved music blend
For true sound reproduction, a speaker must divide sound from an amplifier into high, low and midrange frequencies. Jensen found a way to do this better than anyone else. The CompTrac crossover network. It's computer-designed to more efficiently divide and channel sound

OPC means a whole different kind of speaker system
Be sure and see the new Jensen OPC speakers for yourself. You'll agree - they 're a revolution in sound.
