Zenith Allegro MC4000-49-1271 Woofer Speaker.
Great shape! The sound from these are amazing.
This came out of a Zenith Allegro console stereo from the 70s.
I have many more parts from this unit.
I have 2 speaker sets available.
Right side with sub and tweeter horn
Left side with sub and tweeter horn.
I do believe these are interchangeable so can go on either side.
Each purchase gets you one tweeter and one sub, still attached to the speaker board.
