Lightbulb Radio Shack Super Tweeter

I have a pair of Radio Shack Super tweeters and want to hook them up to my main speakers which are Single Driver. What do I need to buy to add them to the speakers binding posts???

I am an electronics illiterate


Thanks

Do you have a pic or two?

Is this the unit that sits on top and has a rounded blackish case with silver on the front and a little pointy thing in the center?

I'm just trying to remember if there is a built in XO or if that might be a piezo tweeter. Too many moons ago I'm afraid. Can you disassemble it before taking pics?

Ah, the power of google

This one? I see it's fully removeable from the housing for regular mounting. It also has a built in XO, albeit of questionable quality. If you wish to leave it in the housing you can just get some speaker wire, 18 ga. stranded will siffice and hook it up + to + and - to -

It's not a piezo, 'cause it has a magnet, and if it is basically the same as the FT17 then it is pretty decent sounding. How much does it cost each?

Your first DIY project! May it be successful!

You may find that moving the tweeter a little back and forward might make a difference. Also, placing it on a soft wool pad might help. Placement matters, because one wavelength at 5 kHz is about 2.6 inches, so phase relationships will matter.

As for the 89 dB/1W spec; I think I'd suggest considering the pad suggested in the RS manual. That's quite an efficiency difference. If you feel a piercing pain between the eyes, and your ears bleed a little, you will definitely want the level adjustment.
Set the level according to your preference.

Which became blindingly obvious when I found the link.

They sure go back those units. I can remember using a pair when I was in high school, circa late seventies. Is it still being made I wonder? It was my introduction to the term supertweeter.

Default Ebay

I paid $87 US dollars on ebay, probably to much, the last bid went from 40$ to 87$!

Thanks, Bill[B]

I think they dropped this model about 8 years ago. There was a rush to buy up the reminaing stock. I missed out. Maybe wrong on how long ago....

Yikes, I didn't realize they were so popular. They are a good tweeter as I remember but...
