Arrh...RadioShack Doesn't Provide T/S Specs

coolkhoa · 21st March 2004, 09:43 PM

Has anyone measured T/S parameters for RadioShack #40-1033 6-1/2" polypropylene woofer? I just need Qts and Vas for sealed box use.

Thanks in advance.

Maybe if you post a pic, someone will recognize who makes it and you may be able to find out via that route.

Can't really see but,

That looks suspicially like something sold under the Pyramid name. Just guessing by the magnet structure and dust cap. Not familiar with their smaller stuff. I have some 5 yr old 15's that sure resemble yours. Are they 4 or 8 ohm? That might be a clue.

I'm sure there are others with more insight than I.

How's this for a picture? From the 2002 catalog.

Wow, thanks, kelticwizard (and Cal Weldon, too)! I bought some of the last units ($10 each) and couldn't find any specs on their website.

A Qts of 0.72...
