Thielnet SCS4D Speaker
Erin Binal of Bicome finished his lecture on Thielnet by stripping off the front grillw on the small, two-way, IP-addressable, powered SCS4D loudspeaker. There are twin ports above and below the coaxial driver. With the grille on or off, the SCS4D is rated with a frequency response of 48Hz–20kHz, ±3dB. Pricing was not specified. And yes, those are WiFi antennae.
