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.

Pioneer SE-L20


Light, extremely compact open-air type stereo headphones featuring high molecular film diaphragm.

Can a set of stereo headphones weighing a more 205 grams (less than eight ounces) provide the same natural feeling you experience when listening to a conventional stereo speaker system? Pioneer says the answer is yes - and proves it with the introduction of the SE-l20 headphones. These light, highly compact headphones feature a Pioneer innovation - specially designed high molecular film diaphragm which is used in the 1½-inch dynamic speakers. The sound is natural, the response in the treble range is especially excellent, the bass response is rich and powerful.

Tamon TS-808N


The Tamon TS-808N can truly make you feel like you are in a concert hall or disco. This 450W 3-way and  4-speaker system features a 1-1/2 inch aluminum ring horn tweeter, 4 inch twin midranges, 16 inch woofer and a double-port bass reflex cabinet. in addition, a 5-step LED power indicator and tw/mid breaker with tweeter level control will  bring you even more pleasure because  you can control and adjust this system to your own taste while you are listening to it.
 Many years of speaker engineering experience have produced this unique TS-808N, the speaker system that you can enjoy fully with your eyes and ears.

Exclusive Aluminium Die-Cast Ring Horn Tweeter
Tamon's exclusive ring horn tweeter employs a 1-1/2 inch diameter aluminum alloy ring diaphragm.  Its  rigid construction and the specially selected materials contribute to improved efficiency and linearity all the way up to 40 kHz. Transient response is smooth and rapid, too, even at high input levels.

Twin Midgange
Non-pressed cone material, alumi -mylar dust cap and heat resistant voice coil contribute to more realistic middle frequency reproduction of vocals and instrument fundamentals. As most musical energy is in the middle frequencies, we have equipped the TS-808N with two 4-inch midrange units for broader and more powerful stereo reproduction.


LED Power Indicator TW/MID Breaker with Level Control
 A 5-step LED power indicator shows you musical transient during performance through the cloth grille and is equipped  with a waring red Overload lamp. When extremely high signals are loaded onto the tweeter and midrange units, Tw/Mid breaker activates a red waring light and cuts off the excessive signals automatically. The breaker will be reset an dthe sound performance returns to normal when you turn down the amp volume.

Powerful 16-inch Woofer
This 16" large diameter woofer has a rib-reinforced black cone with urethane edge to provide maximum advantage for the twin ported bass reflex cabinet.
Because of the heat resistant brass bobbin and edgewise wound voice coil, this woofer unit can handle power up to 450 W (Peak) while maintaining heavier bass sound reproduction.

Crossover Network
Tamon has developed a 12dB/octave unit with strictly selected quaity electronic components that assure clear undistorted sound quality.
