Re: Specs for old Transsound capsules?
You can't use "voltage-divider calculation", because the FET in the capsule does not act as a resistor. It has a variable I/V characteristic. Actually, most FET's used in low-level electronics are

Re: Specs for old Transsound capsules?
There's no "exactly" the resistance value to use. There is usually a range of resistor values within which the capsule performs acceptably well. And there's variation capsule-to-capsule. Yes, if

Re: Specs for old Transsound capsules?
All these capsules indicate identical*test* conditions, 2V with a 2.2kohm resistor. It does not give any indication of what the resistor should be with a different voltage. As with any buitlt-in FET

Hi Mike The specs of the capsules you mentioned can still be found in the Internet Archives Wayback Machine. Unfortunately, it does not show the images of the frequency response curve, the schematic

Re: Linkwitz to ground/source/drain
Although it's generally the contrary that is asked (modding a 2-wre into a 3-wire), it is quite easy to do. Just connect the source to ground. Another possibility is to connect a resistor between
