Valencias!

Just got a pair of Altec Valencia’s- 846a model. They’ve got the lattice grills, one of which is a bit beat up, as are the cabinets, but they’re pretty presentable and will improve with a bit of work.
Here’s the strange part- all the info I can find says they use the N800 crossover, which makes sense in the Altec world with the 811 horn on top. I was surprised to see that the crossover inside each is a N-500-G! The inside frame has a cutout to accommodate the crossover mounted on the back panel- do you think that was done by the factory or done afterwards?
And could it be that Altec thought it was a good idea to cross over at 500Hz? (If this doesn’t bring Joe Roberts out of the woodwork to rail against his hated 811s especially crossed over so low, I don’t know what will!)
I think I’ll mess with them a bit, maybe try biamping them, and then I’ll plop the Emilar 500s on top and try it that way.
Thoughts? Theories? Suggestions?
Pete

Hi Pete!

I've heard a couple of Valencias in the past but never had them in my system. Didn't they come from the factory with an 800Hz XO with 416A + 811B + 806A? You'll probably get good money for those green N500Gs.;)

Back in the late 90s I owned a pair of 416As, I also used a 605B for my mono system which sports the same woofer. Unlike the 414 which can be operated in wide range mode (unfiltered), IME, this 15 incher needs to be rolled off starting around the 1200-1600Hz range.

If I were in your shoes, I'll start with a DIY N1600C XO and mount the 806A drivers behind the Emilar EH500 horns.

Cheers!🍻

Hi Joseph,

Yes, I've only seen the 800 Hz crossovers in Valencias so I suspect that the N500Gs were put in by someone later, especially from the cutout in the cabinet frame.

The tweeter drivers don't have much in the way of markings - how do I confirm that they're 806A? image17.jpeg(the "R" and "B" markings also make me thing someone changed the crossovers)

Your plan is what I was thinking. Fortunately, I have already put together the HP part of the DIY crossover for my 414/908/32C speakers, so I can start there.

And maybe I can sell the N500Gs and put in a pair of N800F if I want to sell them in original setup. (I might be able to advance domestic tranquility AND get a preferred setup by figuring out a suitable box for the 414s etc.)

Thanks for the help. Be well,
Pete

Yes, the N500G must've been an experiment. Acquiring a pair of N800s is the right way to go if you want to unload those Valencias at a later date.

D16083E2-DEDB-400F-B824-0C191A91EE9B.jpegThe 806A magnet should be about 1/2” shorter than this 802.

As far as I know, the 802 drivers won’t fit in those cabinets without some modification, so I’d assume they’re the 806. But if the crossovers were swapped, it’s definitely worth checking that out. I’m sure you could find some N800F crossovers, if you want to make them stock to sell down the line.

Joseph, thanks for the photo. I didn't get a chance to look last night.
jeb98 - thank you - that's a good point. There's a bumpout on the back of the cabinet that I suspect might have been a modification, but not many photos online show the boring back of the cabinet in original condition for comparison purposes. This is what mine looks like. (and the spot where a beer was spilled on top.) image14.jpeg

E86E9F03-42F3-4AB7-8E99-A3850673E654.jpegIt looks maybe 3/8 shorter, so probably it’s an 806a? But if so, why the need to make room in the back panel. I’m wondering if the 811 itself was remounted with spacers holding it away from the baffle?7344AAD9-3782-4D40-8E11-93AA49E07A0E.jpeg But why would someone do that? Or does this look normal?
I’m afraid to try to take off the already- damaged grills to look, so maybe I’ll just try them as is with a diy crossover, and maybe biamped too.

It's been 20 years since I last saw/heard a pair of Valencias so I can't really say how original or what parts may have been modified in your unit.

Your driver looks like an 806A.

For reference, here's my 802D (~ 2.5") and the later 802/808 motor which has a slightly taller and tapered housing + wrinkle finish.

I’ve seen other Valencia’s and maybe flamenco’s with the extra space in the back panel. I think it’s original
Thank you for that - reassuring that maybe the only thing that was changed is the crossover. That's weird enough.

Thanks Joseph - that's helpful. Onward to the diy crossover mod!

I have a mismatched pair of 808-8B drivers (was actually hoping to possibly mount them in the Heathkit AS-101's I have), but it turns out that one of them is taller than the other, about the difference shown in this example. Annoying as I can't really use them as a pair in this case.

Good find - thanks Joseph! I've seen photos of the thin cover mentioned by alteclipsch a few posts below bowtie2427ss, but since his remark is right below the post of seacliffe301 describing the bump-out I have, I appreciate the evidence that my speakers are (almost) original.

I don't think that playing them with the thundering power of 2A3s risks the HF diaphragms, but it's good to know that they would be easily changed!

Thanks again!
