Curious also, I see other images of the DM4's on the web, where that gray thing is actually has a black cap...example

I just sent Mr. Hardy a pm, maybe he knows. FYI, we played them with the plug in and then out. No difference in the sound. The plug is open on the back side, like a cable might go to it. Was a mystery at the recent GTG enders had.

Might email B&W the pic and question if no one here can answer

May be a port tuner

Got that on the list to do..

Sorry, I was actually interfacing with the Real World for a little bit

Does that plug have two flat blade connectors on it (EDIT: or a blade and a pin*)? It sort of (?) resembles a DIN plug (e.g., as used on European hifi equipment, especially older equipment, from brands such as b&o, Tandberg, etc.).

EDIT: this sort of thing:

* heh, yes it does have a blade & pin, doesn't it?



Pretty sure its a way to use DIN loudspeaker cabling on that loudspeaker, just as some US-made loudspeakers in former times would have both screw connections and an "RCA" jack for connection. Radio Shack, e.g., commonly did this in the 1960s and into the 70s, and not just on their cheap loudspeakers. The idea was to give "flexibility" in connection options. Nowadays they'd probably call them "cable-agile"

Here're some pretty darned typical 1960s European loudspeaker cables

interesting Doc

There's a pair of b&o S45 loudspeakers downstairs that has only DIN connectors on it. Sadly, one of the two speakers' woofers is borked (dragging VC) -- the b&o loudspeakers of that era were pretty nice, actually.

This Tandberg receiver also has DIN speaker connectors on it (FWIW, and since we're sort of on the subject).

Tip o'cap to Doc on that one!

It's funny about that being a Euro plug. When I got my pass amp I had a hell of a time pulling the banana plug caps out of the amp.

I called Pass to confirm that they actually come out and why so tight/difficult.

Response was because that many of the Euro countries don't allow banana style termination.

Yup -- the modern take on banana plug safety, though, is just that. Modern.
"Normal" bananas were still common in (e.g.) the UK in the 1970s -- but the 0.75 inch spaced "double banana plugs" that we (well, some of us) all know and love were anathema in the UK -- because the UK AC mains plugs used a similar enough design that DANGER LURKED in double bananas

I (still) like 'em (double bananas, that is) -- 'cause I am very, very lazy.

My Polk Audio Monitor Series Model 7s sported double banana plugs on their wiring starting ca. 1979 (i.e., shortly after I got 'em).

Another thing that uses those blade/pin style connectors are La-Z-Boy powered seating. I had to replace several of them on my La-Z-Boy Matinee Theater recliners after the pins broke-off on three of them. Of course once the pin breaks off, it gets stuck in the female connector and is extremely hard to get out. I ended up replacing all of the male and female connectors with new.
