You'll need to build a corner (two bits of heavy sheet?) then......

These were designed to fit into the room's corner, the side walls forming the enclosure.

If it was built in, that would have solved the sand retention problem [as opposed to just relying on the side walls] but making a free-standing unit out of it shouldn't be that difficult

If it needs to be loaded ie it's not a vented design the sand could be in bags or there are alternatives. You might get a great result like Whaam [in Success Stories] and his "fab" Cotswold Speakers.

Thanks for the Barron Knights link Julie-I'd forgotten that one.
Set against the incredible music in the sixties we thought them incredibly naff but watching them perform in a Night Club setting a few years later was an almost hysterically funny experience!

Yes as Trev mentions this looks like an original Wharfedale corner speaker .......specifically the 9cu ft sand filled corner panel 2 speaker system as detailed on p309 of “A pair of Wharfedales” ...in the book it’s in the cabinet construction sheet Sept 1957....fab speaker indeed :0)

Either they took the original design and built the front part into a corner or a free standing unit was dismembered and put into service. These designs were the bees knees at the time. There was one in Practical Wireless as well as I recall. Imagine having to visit the builders yard re your Hi Fi

Or even mix concrete and apply it to the inside of 3/4" plywood panels on which nails were distributed at random. I was keen to do all that and remember wishing that I had a house where I could build two units in the corners of the front room. They were a very good design but really, the gold plated cables of their day. My best audio system was a deck on a board supported by three bricks and played through a Sobell Radio

When I went to stereo it was an SP25 with recycled bits but that sounded great as well, mainly because I couldn't have afforded a commercial system and had some money to buy records!

I built something similar with a sandfilled baffle ( influenced by Gilbert Briggs of Wharfedale loudspeakers ) This was back in mono days 1957 I think!.

I could not afford Wharfedale multi units and used a Goodmans Axiom Mk 12" full range speaker.

The speaker in your pic has a massive magnet and the tag "low resonance" leads me to believe it is a bass driver. Wharfedale, Vortexion, Vitavox all made big magnet speakers.

The rotary switch is likely to be to select different crossover points between drivers in a multi unit system. This can aid in optimising the whole system to suit the room characteristics.
