NOS 604-168X pair.

Oz Ebay: eBay Australia: Buy new & used fashion, electronics & home d

The seller provided me with the cone numbers: one is 18030 35401-01, the other is not as legible but looks to be the same.

Serial numbers: K126798 12-81, and K126803 12-81

How do these sound compared to other model 604s?

Edit(addition): I have a 416-8B with a correct cone #18030 35400-01 and a 421-8H with a correct cone #35402. In January 1999 Altec listed the 035400 in the recone kits for the 604(8K, 8G, 8H, 16E), the 416-8 and the 515, and #035662 for 515-8GHP, 515-16GHP, 515-8G and 515-16G



Any info on the #35401???????

A bit light in the lows. fine with subs.

The Ebay seller has added clear pics of the S/Ns and cone numbers.

Some more info. The Altec/Mark lV Repair PartsLlist(March 1, 1996) lists the recone kit #R904/604-8HP for the 604-168X, 604-HPLN and 904-8A LF speakers. This kit has a LF cone described as HI POWER. Unfortunately I have no information re the cone part number for this kit. Other model LF drivers are listed as having a HI POWER cone. Altec may have used one of those cones or come up with one for the 604-168X, specifically. Another Altec mystery, maybe.

The 604-168x are for high power Bi-amping. They don't sound as good for Hi-Fi or HT apps... You would be better with a 604-604H for home listening.. These are the drivers you will find in say Stanley Screamers... They need augmentation in the bass and the HF IMHO.

Thanks for your replies.

Change the HF frams to all alum, and these are just fine.
Very similar if not exactly the same as the 904-8A.
They don't go much below 70hz but are wonderful with subs.
FWIW, I paid $400 for my mint pair of 904's with x-overs. I think that price is WAY too high and they are too far away.
