[Nanook]

been there..

no "D" version.

I think the "C" is similar...., just different mounting for the tweeter...

 

[Geoff H]

I have found an "E" in the 89 brochure.

So the D may have been somewhere between 1975 amd 1989.

Regards,

Geoff.

Edit, try asking in the Altec Lansing forum under Loudspeakers. Cal or GM may have some info.

Hi Nanook,

Try here:

Just search for 8" and discontinued. Leave everything else as undetermined.

HTH. Fell on it by accident!

Cheers,
Geoff.

The 409 is just a commercial speaker and nothing fancy at that. It is not really suited for home or hi fi applications. I have put up 1000's of them over the years.

Geoff, That's a good site, thanks.

burnedfingers, I agree, the 409's I had were nothing special, but very efficient. Don't know which version I had, too many years ago. I believe the surround was paper and the tweeter was mounted across the front of the basket not the pole piece. Nice Altec green colour though. 😉

This is the "hi-fi" version out of the Atlantic. Same magnet and basket structure as the 409. I don't know why, but these have a ferrite type rear pole plate.

Not the best 8-incher made. Better if you cross to a bigger woofer at 100 Hz or so. These have had a bit of cone treatment to fix the top end.
