Frequently Asked Questions about NSI-25M

What is the rated power of the NSI-25M from Nakamichi?

The NSI-25M from Nakamichi has a rated power of 15 watts. This power allows the midrange driver to be used efficiently in various audio applications while ensuring excellent sound quality. The peak power of the NSI-25M is an impressive 100 watts, enabling it to handle short, intense audio level peaks effortlessly without compromising sound fidelity. These features are ideal for users who value specifications that optimize both performance and audio integrity, especially when installing multi-component audio systems.

What is the size of the NSI-25M midrange driver from Nakamichi?

The NSI-25M from Nakamichi is a compact 3-inch midrange driver with a size of 64 mm. This compact design is perfect for applications where space is limited but excellent sound performance is still required. With a mounting depth of 31 mm, this midrange driver can also be integrated into a variety of speaker enclosures without compromising the installation environment. Its compactness makes it popular in modular audio systems, where space and weight are crucial while still maintaining excellent sound reproduction.

What frequency ranges does the NSI-25M from Nakamichi cover?

The frequency response of the NSI-25M from Nakamichi ranges from 200 Hz to 20 kHz. This means that the midrange driver is capable of covering a wide range of frequencies that are essential for clear and detailed audio experiences. The lower frequency range of 200 Hz provides warm midtones, while the upper limit of 20 kHz allows for the reproduction of high frequencies and fine sound details. This bandwidth makes the NSI-25M ideal for demanding sound installations where precision and detail fidelity in the mid-frequency range are crucial.

How sensitive is the NSI-25M midrange driver?

The NSI-25M from Nakamichi has a sensitivity of 88±3 dB. This sensitivity describes the degree to which the speaker responds to an input signal and produces an output volume. A sensitivity of 88 dB is considered efficient, meaning that the midrange driver is louder at the same input level than less sensitive models. The specified variation of ±3 dB indicates minimal variances, which, in practice, have little impact on overall sound reproduction. This is particularly advantageous in speaker systems that operate in variable acoustic environments.

What impedance does the NSI-25M from Nakamichi have?

The NSI-25M midrange driver has an impedance of 4 Ohms. This impedance is typical for many car audio systems and ensures that the speaker delivers optimal performance with most amplifiers and audio systems that are also designed for 4-Ohm operation. Additionally, the combination with a KSV voice coil and a neodymium magnet allows the NSI-25M to provide consistent, reliable performance. This technical specification is crucial for system sizing to ensure that the electrical requirements are compatible with the existing equipment.

What materials are used in the NSI-25M from Nakamichi?

The NSI-25M from Nakamichi uses a KSV voice coil with a diameter of 25.5 mm and a neodymium magnet with a diameter of 25 mm. The KSV voice coil is known for its excellent temperature resistance and robustness, making it ideal for applications with high power peaks. Neodymium magnets are known for their strong magnetic force in a compact size, contributing to a more efficient speaker design. These materials ensure high performance and durability under various conditions and highlight the technical sophistication of the midrange driver.

What is the weight of the NSI-25M midrange driver?

The NSI-25M from Nakamichi has a net weight of approximately 260 g. This lightweight is advantageous when it comes to the installation and placement of the midrange driver in various enclosures and vehicle environments. Especially in applications where weight plays a critical role, such as in mobile or portable audio installations, the low weight proves beneficial. Despite this lightweight construction, the NSI-25M offers robust and durable performance that both audiophiles and technicians appreciate.

What advantages does the installation depth of the NSI-25M offer?

The installation depth of the NSI-25M is 31 mm, making it extremely flexible for integration into various installation locations. This shallow depth is particularly advantageous for car audio applications, where space is often limited, such as in door panels or dashboards. The compact installation depth allows for easy installation without extensive modifications to the vehicle and helps ensure that the midrange driver can be seamlessly integrated into existing audio systems. This makes it especially attractive for applications with tight space constraints.

What tips are there for installing the NSI-25M from Nakamichi?

For the installation of the NSI-25M from Nakamichi, it is particularly important to consider the compact installation depth of 31 mm, which allows for a variety of mounting locations without compromising sound quality. Since the midrange driver also has an impedance of 4 ohms, the amplifier used should be compatible to fully exploit the sound potential. The use of the KSV voice coil and neodymium magnet further ensures stable and efficient power transfer. Experiment with different positions and angles to achieve the ideal sound distribution, especially in confined environments.

How can the NSI-25M be optimally utilized in a sound installation?

The NSI-25M from Nakamichi can be optimally used in multi-way systems due to its wide frequency range of 200 to 20 kHz, as it is capable of accurately reproducing critical frequencies as a midrange driver. The combination of a nominal power of 15 W, a peak power of 100 W, and a sensitivity of 88±3 dB makes it suitable for use in home theater applications as well as in car audio systems. The specific choice of materials, including neodymium magnets and the KSV voice coil, allows for a longer lifespan and resilient performance, even under demanding conditions. Use these features to achieve a balanced sound experience.

Used as replacement to Škodas canton system

Used as replacement to Škodas canton system subwoofer.
Works great, fits right into the factory box, need to remove only one little pin and use new skrews.
Sound is even better then it was before.
Plug and play for that system.

Richtig guter Tiefmitteltöner mit Alu-Gusskorb

Richtig guter Tiefmitteltöner mit Alu-Gusskorb und um 30Hz niedrigerer Resonanzfrequenz als üblich im 10cm-Woofer-Bereich. Dadurch kann sich dieser 10cm-Woofer auch wirklich Tiefmitteltöner nennen.

Real power

Ziet er goed uit,Heb 2 accu`s aangesloten, Daar tussen Stinger scheidingsrelais van 200 amp,
Ook moet je 2x zekering van 200 amp plaatsen,

Heb bewust voor Stinger 200 ampere gekozen omdat ik een standaard dynamo heb is dat voldoende.

Enormer Druck, Top Klang

Nachdem ich mit meinem Bass Habit Elite 300 zufrieden war jedoch noch etwas mehr wollte bin ich auf dieses gute Stück gekommen.
Beim auspacken bin ich direkt von dem massiven Magneten und der guten Verarbeitung überwältigt gewesen.
Getestet habe ich ihn bisher mit einem Deaf Bonce Atom 3.5k Verstärker.
Das Teil ist der absolute Hammer und einfach eine Macht.
Preis-Leistung stimmt hier definitiv !

First DSP

This is my first DSP amplifier. It have good build quiality, i use it together with Focal EVO PS, and sound is really good. Cant compare with something else but i like it a lot.
For price around 400 this is very solid DSP, but if you spent more you could get HELIX and it will have better configuration software, at least in helix soft, you could copy paste eq properties from REW. Here you need to set all manually one by one.
