The Infinity A1201b-H Alpha 40 Tweeter is a high-performance component that delivers exceptional sound quality for music and home theater applications. This tweeter is part of Infinity's Alpha Series, which is known for its innovative design and superior sonic performance.
The tweeter features a 1-inch (25mm) aluminum dome that is partially recessed, allowing it to blend seamlessly with larger speakers while providing excellent dispersion and detail. The dome is shaped to minimize distortion and provide a wide frequency response, ranging from 1.5kHz to 35kHz.
The motor structure of the tweeter is designed to reduce distortion and provide accurate and detailed sound. It utilizes a neodymium magnet, which is lightweight yet powerful, allowing for faster response times and improved efficiency. The tweeter also features a vented voice coil former, which helps to dissipate heat and maintain consistent performance over long listening sessions.
The Infinity A1201b-H Alpha 40 Tweeter is designed to be used with a wide range of crossover networks and enclosure designs. It is compatible with both 2-way and 3-way systems, making it a versatile option for custom audio installations. The tweeter also includes a removable grille, which provides both protection and a subtle aesthetic touch.
In summary, the Infinity A1201b-H Alpha 40 Tweeter is a high-performance component that delivers detailed and accurate sound. Its partially recessed design allows it to blend seamlessly with larger speakers, while its innovative motor structure and aluminum dome provide excellent dispersion and frequency response. Whether you're building a custom audio system for your home or upgrading an existing setup, the Infinity A1201b-H Alpha 40 Tweeter is an excellent choice for delivering exceptional sound quality.
Buying a partially pushed Infinity A1201B-H Alpha 40 tweeter dome comes with both advantages and disadvantages. Let's examine each in detail: Advantages:1. Cost-effective: A used or refurbished tweeter with a partially pushed dome may be available at a lower price than a new one.
2. Availability: These tweeters may be more readily available on the second-hand market, making it a viable option for those who cannot find a new one.
3. Experience: For audio enthusiasts and DIYers, repairing and modifying an existing tweeter can be a valuable learning experience.
Disadvantages:1. Unpredictable performance: The performance of a partially pushed tweeter dome can be inconsistent as the dome may not move uniformly, affecting sound quality.
2. Limited lifespan: A damaged dome has a reduced lifespan and may require frequent replacement, increasing long-term costs.
3. Potential compatibility issues: The partially pushed dome may not be compatible with some speaker systems, limiting the tweeter's versatility.
In conclusion, purchasing a partially pushed Infinity A1201B-H Alpha 40 tweeter dome can be a cost-effective solution for those looking to save money or gain experience in audio repair. However, the inconsistent performance, potential compatibility issues, and limited lifespan should be carefully considered before making a decision.
If you prioritize high-quality sound and consistency, it is recommended to invest in a new tweeter. However, for DIYers and those who are comfortable with the risks and potential challenges, a partially pushed tweeter could be an intriguing option.
Details:
I intend to include the covers they are mounted in, for easy installation. I have two 1 tweeters removed from a set of Infinity alpha 40 speakers. Packed well for the journey. If you want me to remove them from the covers, I can do this for and ship in a smaller box.
I have adjusted the price to reflect this.
