Need Help with Speaker Cable ID. What are they?

Type 4 has 4 solid core conductors.

I don't think you'll be able to ID the cables. Any company like AQ or TARA would have writing on the jacket. They look like good quality bulk. Also, depending on how big the company is, and who they sell to, the same exact cable may be offered in different color jackets, so the dark blue doesn't necessarily mean anything. If you are looking for something similar to replace it, Canary would be a good option. Its not expensive and its probably even a little better quality.

Multi stranded? GAG! Not AQ that's for sure."

Actually, AQ does make some stranded cables.

I know for sure that its not Midnight. Midnight is solid core and the OP's cable is stranded. Also, its labeled AQ Midnight non stop down the length of the cable. Too bad for the OP its not Midnight, its a very nice cable.

.....Meaning they weren't wafer thin strands. The original Midnight had strands exactly like his pic. Maybe the later + and hyperlitz versions didn't."

Its not Midnight. The OP's picture has 4 internal multi-strand conductors. 2 red and 2 black. The origional AQ Midnight looked similar but it wasn't the same. All of the solid core conductors, while smaller than typical, each had their own jacket. And yes, they were not configured like later versions of midnight. The strands were braided similar to how Kimber's look. Its easy enough to verify. Just call AQ and have them look at the OP's pic.

I was a dealer at the time when those cables were current. The OP's cable was not the same as the original Midnight. If you can find some old sales literature or a box, AQ always shows a cross section of their cables. The link to your pic was no good. Its very likely that you either had a fake set, or its possible you may have had a set of demo cables. During the design process, AQ makes up test cables and gives them out to dealers and people they know, so they can get some input. Even if it was labeled Midnight, It still could be a test cable. The Midnight jacket may have been the right size for whatever they were making up. That would easily explain why they are having a hard time matching one of their production cables to your pic.

Did you mean the link didn't work or that the pic doesn't help?
Here's the link and I did test it but you have to cut and paste it of course.

I just tried it and got this message:

It looks like the address isn't bad. I guess I don't have all the requirements you need to access where your pic is.
