Initial testing Frankenstein DIY 3 way speakers. Altec style.

Altec 290-4G (4 Ohm) Compression Drivers (Giant Voice)
Altec 311-60 Horns. (Fresh paint job)
Utah 12” woofer (8 Ohm)
Realistic Super Horn Tweeters (8 Ohm)
I built custom crossovers using Solen Hepta-Litz inductors on the mids and highs and standard on lows…
Selection of Pio caps and MKP.
Vitamin Q. Russian Hybrid Pio
Jensen polystyrene, Mundorf, Jantzen, (will experiment with others aswell)
Low X-Over point 500Hz
Hi X-Over point 5000kHz
Sounds huge…
Still tweaking levels between the 3 frequencies.
Waiting on L-Pads for the tweeters so I can dial them in…
Too bad these are stuck in the basement. No space in the living room…
One day….

Should not any object cause vibration of sound of or-resonance surround sound ( echoes)

Did you build a passive crossover?

[@Maxxzinno]

Yes I did
