Oaktron by MISCO is a premium line of high performance, ready-to-ship transducers and drivers for a wide variety of applications including high fidelity, arcade, and casino games, automotive, aerospace and many more. From elegantly simple to highly specialized designs for unique and demanding applications, there is an Oaktron loudspeaker perfectly suited for your needs.
MISCO engineers use the world's most sophisticated loudspeaker measurement systems including the Klippel Analyzer to maximize and confirm the speaker's design, as well as the Klippel QC module to ensure perfect unit to unit consistency and reliability.
* Note: Protect your system's tweeters. Allowing lower frequencies to reach a tweeter can cause lasting damage. Use a passive or active high-pass filter (crossover) with this tweeter, and a simple first order (6 dB/octave) of a proper value capacitor to block low frequencies. MISCO suggests using a crossover that includes a capacitor and an inductor to achieve steeper low-frequency filtering of 12dB per octave. See the specifications of this tweeter for the smallest recommended crossover frequency.
This tweeter is ideal for use in a wide variety of applications including:
- Home audio systems
- Home theater systems
- Automotive and motorcycle audio speakers
- Arcade speakers
- Casino gaming cabinets
- Smart devices and speakers
