Nov 28, 2012 · From the Fostex T90A datasheet, a crossover point of 7 kHz or greater is recommended. For a crossover, we have had good results using a simple first-order crossover (one capacitor) operating in the 10 to 14 kHz range.

Apr 20, 2020 · I'm going to build rear-firing SuperTweeters using Fostex FT17H's as an add-on to my Soliloquy 6.3 main speakers. From what I've read from searching AK and elsewhere, it seems like 1.5uF (7k crossover) is most commonly used, though I'm also thinking about a 1.0uF (10k crossover) since many seem to believe "higher crossover is better".

Oct 12, 2023 · In this blog post we look at implementing a passive high pass filter for the stock Fostex T900A. Since featuring the tweeter in a recent blog, I was asked to develop a proper high pass filter for the super tweeter. The goal is a 12dB/octave high pass slope at 7kHz to mate up with the midrange horn. First we will look

Dec 24, 2017 · The crossover frequency should one octave over the own resonance of the driver. The attenuator should not be used, because the non linearity causes the crossover not to function correctly.

Feb 18, 2024 · I have just bought a pair of fostex t90a super tweeters and are wondering the best way to wire them in capacitor or crossover as have never done something...

Sep 4, 2019 · The crossover will be the passive one recommended by Fostex according to the drivers that I bought, DECISION DONE. The power amp will be a normal stereo amp, DECISION DONE. Doubts:

Jan 1, 2018 · Inspired by Fostex brand of ultra-high frequency circuit, After the test improved, in the original frequency capacitor to increase the frequency inductor, you can filter out the inclusion of high-frequency signal in the low-frequency signal, the high-frequency sound more clearly, reduce the high-frequency diaphragm under the large signal ...

The CX film capacitor series is for crossover such as tweeter add-ons. In order to maximize the tweeter's acoustic performance, the CX film capacitor series is de-signed to take into account the effects of condenser-specific sound quality. Acoustic performance was determined for the use of Fostex tweeter as add-ons.

From the Fostex FT17H datasheet a crossover frequency of 5 kHz or more is recommended. We have had good results with this tweeter using a first-order crossover in the 10 to 15 kHz range. You can use an L-Pad attenuator to match the tweeter level to your speakers.
