Hello Krikor,
Looking at the picture, you can barely see 2 wooden boxes (on each side of the Pi 4s). These boxes housed a 1uf cap and an L-pad. The T90 are coming in at 18k. It is also helpful when you integrate the T90 that the voice coil of the tweeters be at the same plane as the voice coil of the horn driver to avoid phase errors. Godspeed.

Thanks for the info... I'll have to keep this in mind when I build my 4Pi and if I add the T90. What type of L-Pad are you using (specs)?

Thanks again.

Hi krikor,
My L-pads are Fostex R80B. I got them when I got the T-90s many moons ago. According to Madisound site, R80Bs are 100w L-pads. Godspeed.

Is that a Birdseye maple veneer? Where did you get it? It's lovely.

Hello Sir Frihed89,
Thanks for your comment. The speakers were veneered using plain maple and not bird's eye. They were darkened a little bit from the application of the topcoat I guess. Godspeed.
