Mono speaker for Bluetooth listening.


Data for Home made
ProductionThe Netherlands, 1955.
CabinetWood. Size 39x39x16cm.

The Design

The speaker looks very nice, but appears to me to be a home made product. For a professional factory speaker, I'd expect the finishing to be a bit more smooth. A dark varnish was applied to make all the lining of the wood invisible.

The nicest wood was used in the side panels, these are made of solid wood (oak presumably). The front is made out of plywood, possibly also oak because it has the same color, but the lining of this panel is less beautiful that the side panels.

But when was it made? The listed 1955 is just a wild guess here. The speaker has the pen marking 465KY, so might have been used in an Erres KY465 set (of 1946); this would be in line with the stamp 28 46 6 on the speaker, which could be a date mark. Perhaps the Erres went defective ten years later and the speaker was recycled, but this could also happen after 20 years.

The back edges of the side panels have a groove that suggests that a back panel has been there some time. Maybe the cabinet is older (as was suggested to me, German from the thirties) and later repaird with the Erres speaker.

This Object

To use this as a speaker for a Bluetooth set, but also use it for other purposes, and use the Bluetooth set alone, I fitted a 3.5mm plug. Impedance is 8 Ohms.

As Bluetooth speaker, I took a small cheap unit, we refer to usually as Wit Eitje (White Egg). The size of this unit is about 10cm. I openend it and fitted a 3.5mm switching jack in the speaker connection. Eggie can now be used as before with the same well-known sound quality, but the oak speaker (or any other low impedance speaker with 3.5mm plug) can be connected to play the sounds through it.
