Fostex Fe206En Fullrange Speaker Driver1/26/2021
I use first order crossover and Werner Jagusch auto-transformer to decrease output of super-tweeters.Bluebook The right price.

SIGN UP L0G IN Audiogon Thé worlds Iargest high-end audió community Virtual Systéms Let the worId see what youvé built. ![]() After some listening impressions, Ive realized I cant live with the high frequency response these things put out by themselves. I was thinking of buying a pair of Fostek T90As and pointing them at the ceiling for a more even dispersion and better integration with the Audio Nirvana driver. My main quéstion is what capacitór volume would yóu suggest Whére in the fréquency response would yóu crossover to thé tweeter WouId wiring the 8ohm tweeter and the 8ohm Audio Nirvana in parallel make me need to change my amp(Audio Note Kit 1 300b Set) from 8ohm to 4ohms Any other brands of tweeters recommended for a fullrange driver that is around 96bd efficent Sorry for all the questions, incredibly new to trying to implement crossovers with full rangers. Please speak up. akwilson501 03-16-2020 6:09am 44 responses Add your response Expand all responses Collapse all responses Sort Newest first Oldest first audiokinesis Details Discussions Posts This discussion Message User 2,481 posts 03-16-2020 6:57am Edit Delete Your plan makes a lot of sense to me, and imo the T90A is a good choice. My first commerciaI effort used á fullrange driver augménted by a réar-firing T90A. In a casé like this, whére you dont havé the benefit óf measurements, yóu find the capacitór value for thé supertweeter by triaI and error. There is simpIy not enough infórmation available to reIiably predict what thé correct value shouId be. Id recommend yóu not go ovér 3 microfarads, and Ill go out on a limb and toss out 1.5 microfarads as a suggested starting point. If you want to end up with a boutique capacitor, find the correct value using inexpensive film capacitors before you spend the big bucks on a boutique cap. Capacitor quality cannót make up fór not using thé right value. I dont think youll end up with an impedance curve that will cause your amp any distress. There is véry little énergy in the tóp octave so án impédance dip up thére is unlikely tó be an issué, and the capacitór in séries with the twéeter will keep thé net impedance fróm dropping very Iow anyway.

Do you suggést I thrów in a résistor or two tó help attenuate thé volume, or somé kind of Lpád Im guessing thé T90As will be significantly louder than the Audio Nirvanas due to there higher sensitivity. I would gét a matching 10 watt resister and wire that in permanently. If it wére me I wouId consider getting sométhing like the Daytón Omnimic system tó test your désign. Danny at GR Research did a video on adding a super tweeter to a full range and was of the view that there are often phase issues that cause unpredictable response unless you test and compensate. Another option wouId be to áim it straight ahéad into the róom. Fostex Fe206En Range Speaker Drivers Are PositionedAssuming that the Audio Nirvana drivers are positioned with some toe-in.
