Everyday electronics article needed ( 1992 ! )

[Paul Smith]

Hi all,
I wish to build a subwoofer like a friend of mine's. It's to a
design in Everyday Electronics August 1992 edition.

He has still got a copy of the pages relating to the build of the
project, but does not have a copy of the "Shop Talk" pages. This has
important details about the specifications of the loudspeakers to use
in the design ( I hope ! )

Can anyone out there help?

Anybody out there built one? My friend's sub is brilliant !

Regards,
Paul.

I *should* have a copy of that issue at home somewhere - I'll take a look
tonight and scan you the Shop Talk page if I can find it...

Hmm,

I see what you mean!
The article goes on about Three important speaker parameters, Qts Vas
and the Free Air resonant frequency - then doesn't specify them !!! I
hoped the ShopTalk article would at least tell you the Spec of the
speakers or give you a part number.

At least I now have an address to follow up on.

Thanks for your time and effort - much appreciated.

Regards,
Paul.
