Speakers

Model 1448 was one of the first models which had a two way speaker system (see foto below), what was called high-fidelity sound, or, more common: HI-FI.


But not all customers were ready for this sound improvement, so on this amp-unit, a switch (F) was mounted to deliver the old sound. Which would mean that the tweeter would then be switched off, thus the sound only coming from the woofer!

The internal speakers are:

1x 15″ JENSEN Speaker (woofer), used by many jukebox manufacturers. That might be one reason why JENSEN and Rock’n Roll are often used in the same manor.

 

 

 

 

 

 

 

The C15N/8 is an ideal replacement for those with a field coil used in Rock-Ola 1448 and 1454. It can be used in other AMI, Seeburg, and Wurlitzer jukeboxes as well. Though it does not have the AlNiCo magnet the sound is very well.

Please note: The winding of the field coild should be replaced by a min. 50 Watt load resistor.

1x Hi-Frequence rectangular horn

 

Piezo Horn Tweeter as a good value replacement for the high frequency horns used in some Rock-Ola, Seeburg, and AMI jukeboxes.

Size:80 x 186 mm
Depth:105 mm
Outer hole width:170 bzw. 67 mm
Frequency:1,8 – 20 kHz

This Piezo Horn can be installed without crossover network. A small resistor might be used in serial connection.

External Speaker

What I know three models of spearkers could be connected external to the jukebox.
