Anyone heard of United Acoustic Speakers?

Hi,

I found a used tower speaker labeled United Acoustic UA-7 at a used hifi market. Average sized tower speaker with the label on the back stating the name, Serial no., "Impedance: 8 ohm, Power Handling 15-250 watts, Sensitivity 92 dB and address: United Acoustic Technology 2815 Baldwin Avenue # 12 El Monte, California 19731. with USA written at the bottom right of the label. It had 2 binding posts for + and -

No amount of googling resulted in any info about this. Are they really old or unknown? I'm tempted to give it a listen. Since there were tons of stuff I only took a picture of the label at the back. I am very curious I hope someone can tell me before someone else grabs it.
