Unusual Speaker Designs

[MarkS]

Exactly! In the world of cables, if you can't see it, you can't hear it ...

115db @1Hz is impressive. Rated frequency range is 1Hz to 20Hz. http://www.eminent-tech.com/

Thin and tall

Nice Brion-Vega Algol re-issue TV though. I had one from the 2000s that I donated to my broadcast engineering company once analog TV was switched off.

I meant the Speaker design, not how the owner ran his cable. The connectors on the back of this 7 foot tall speaker. Are 3 feet above the ground plane.

Built in cable risers to save you from having to buy them your self.

This looks like it couldn't possibly work.

Bruce Thigpen is a genius and thinks out of the box. The fan blades are servo controlled. The device is also very low in distortion, or so I'm told. Rotary "woofer" in action. Another demo.

Those look like the perfect speakers to play George Antheil's Ballet Mecanique, which included airplane propellers in its instrumentation.

What brand are these? Remind of the (unfortunately) discontinued Philips Soundsphere models

I like that speaker and the tweeter is gorgeous, reminds me:

Actually, pressure inside the box does change, but the pressure of the air enclosed between the two woofers membranes does not change. And yes, it is an old invention by genius Harry Olson. It cuts required box volume in half and lowers the second harmonic distortion.

Jamo had a similar arrangement for decades in their "push-pull" designs. I first saw them in the early 1980s and they continued right up until the 2000s. I have a pair of 507as in my listening room at the moment. Twin 6.5" opposed internal woofers exiting via a large diameter rear port. Crossed over at 150Hz to twin 4" mids in a MTM like, narrow front, curved-side design.

They have very low THD across the board.

Literally everything from this company looks like a teacher explained speakers to a classroom full of 9 year olds, and then had them draw their designs: https://oswaldsmillaudio.com/loudspeakers

I personally really like the look of some of them, haha.

Definitely skeptical of the performance, though. Their biggest selling point(they mention it in every video) is that their speakers use "conical horns", and sound like the way speakers used to a long time ago.

Missing is the room with the fan-sized hole in the wall.

We only have bullet holes around here.
