The Jensen SG-80 8 Speaker is a remarkable addition to any audio system, delivering rich, clear sound with a vintage twist. This 8-ohm speaker is part of Jensen's Sigma Alnico series, which is renowned for its high-fidelity sound and classic design.
The SG-80 speaker features a 10.5-inch (26.7 cm) aluminum cone with a paper surround. The use of aluminum in the cone results in a lightweight yet rigid structure, ensuring excellent response and minimal distortion. The paper surround provides the necessary flexibility for the cone to move freely, producing accurate and detailed sound.
At the heart of this speaker is a powerful neodymium magnet, which is lighter than traditional magnets but offers superior magnetic force. This allows for increased efficiency and better sound quality. The magnet also houses a 1.5-inch (3.8 cm) Alnico V magnet voice coil former, which contributes to the speaker's ability to produce a wide frequency response and a smooth, natural sound.
The Jensen SG-80 speaker is designed with a classic appearance, featuring a vintage-style cast-aluminum basket and a distinctive copper colored spider. The speaker grille is covered in a sturdy, black metal mesh that protects the delicate components inside while allowing the sound to freely pass through.
This speaker is suitable for a wide range of applications, from home audio systems to professional recording studios. Its 8-ohm impedance makes it compatible with a variety of amplifiers, and its high power handling capacity of 150 watts RMS allows it to handle even the most demanding audio sources.
In summary, the Jensen SG-80 8 Speaker is a high-performance, vintage-style speaker that delivers rich, clear sound with a wide frequency response. Its lightweight yet rigid aluminum cone, powerful neodymium magnet, and classic design make it an excellent choice for any audio application.
The Jensen SG-80 8 Alnico speaker is a popular choice among guitar players and audio enthusiasts due to its distinctive sound and high-quality construction. Here are some pros and cons that might help you decide if this speaker is the right choice for you:
Pros:1. Authentic Alnico Sound: Alnico magnets are known for their ability to produce a warm, clear, and detailed sound. The Jensen SG-80 delivers a classic Alnico tone that is beloved by many guitar players.
2. Durable Construction: The speaker cone is made of paper, which is a traditional material for guitar speakers. The aluminum frame and Alnico magnets are also robust, making the speaker durable and long-lasting.
3. Versatile: The 8 impedance makes the Jensen SG-80 a good choice for a wide range of amplifiers, from low-wattage to high-wattage models.
4. Low Frequency Response: The speaker has a relatively low frequency response of 50 Hz, which makes it suitable for producing strong bass and midrange tones.
5. Hand-Built: Each Jensen SG-80 speaker is hand-built, ensuring that every unit meets the highest quality standards.
Cons:1. Expensive: Compared to other 8 guitar speakers, the Jensen SG-80 is pricier. This might be a deterrent for those on a tight budget.
2. Sensitivity: The speaker has a low sensitivity of 85 dB, which means that you might need a more powerful amplifier to drive it effectively.
3. Break-in Period: Like many Alnico speakers, the Jensen SG-80 requires a break-in period of several hours to reach its full potential.
4. Heavy: The speaker weighs around 10 lbs, which might make it challenging to transport or install in certain setups.
In conclusion, the Jensen SG-80 8 Alnico speaker offers a unique and authentic sound that is appreciated by many guitar players. Its durable construction, versatility, and low frequency response make it a strong contender in the guitar speaker market. However, its high price tag, low sensitivity, and heavy weight might be drawbacks for some.
If you are looking for a high-quality Alnico speaker with a classic tone and are willing to invest in a premium option, then the Jensen SG-80 could be an excellent choice for you. However, if you are on a budget or prefer a lighter and more sensitive speaker, then you might want to consider other options. Ultimately, the decision depends on your personal preferences and requirements.
