Yep I bet it's a treat to listen to. Nice to see things for sale in their environment as well, not just a pair of speakers on a table like a lot of sellers in my area.

I may have these in my garage if anyone is interested.

Hickory. Not sure what I am going to do with them yet. Might update the crossovers.

These are SDA-1B I think but I'll verify when I get them opened up.

Looking at the blade/blade socket I'd tend to agree. If they have 4 mw6509 that will seal the deal.

Well I'm not sure those are SDA 2a. I've never seen the SDA 2a in that cabinet configuration WITH a pin/blade socket.
-
According to SDA Handbook based on the cabinet design (fig 3.8) and the pin/blade connector they would be 1987 or 1989 version SDA2B's depending on having polyswitches in the crossover.

No Affil.
Any idea what this configuration is attempting?
The speakers are Monitor 10's, the terminal cups are labeled SDA II have two fuses and an SDA connector. There has been another MW installed in the rear panel.

The original SDA II was a 3 driver speaker. I can only speculate the the bottom driver was a bass driver. The top two drivers were 1 stereo and 1 dimensional. It was a blade/Blade interconnect in which both blades carried signal. What that mess is, just that a mess. The rear woofer may be the bass driver. I do not see two connectors for the interconnect with that 3rd binding post.
