this?
Don't ask me how I found this, magic? I thought they looked like mirage speakers, so I typed mirage pentagonal speakers into google, and it gave me this as one of the first images
edit:
Wait those have a tweeter on top, I think these are them

"High End USA Made Soundwave Soliloquy Tower Speakers in Very Good Condition Fully Tested. Made from 1989-93 in Rochester, NY by Fidelity Soundwave these speakers sold new for $2,500/pair (that is in early 90's dollars). Each Tower speakers features two 8" woofers and two 1" tweeters in a unique 5 sided acoustic suspension design that is 38 5/16" tall x 16" deep x 12" wide. They are in a matched pair with a dedicated right and left speakers, original carpet spikes included (not shown). These sound very good indeed, Soundwave speakers have been very favorably reviewed in the Absolute Sound magazine. From the manufacturers design statement:
"Soundwave Point Source models acknowledge the simple acoustic fact that any wavelength of sound shorter than the width of a loudspeaker's front panel is mechanically distorted. Those familiar with the physics of wave propagation understand this. Further, any frequency which has a wavelength shorter than the width of a loudspeaker's front panel will be heard more than once by a listener. That is, the listener will first hear the direct sound, and then, microseconds later, its reflections off the baffle or diaphragms. This seriously degrades transient response and stereo imaging, and alters tonality.
Point Source loudspeakers have a unique "V" -shaped cabinet with the point of the "V" facing the listener. A special high-frequency drive unit located at the point of the "V" is flanked by two bass/midrange drivers oriented in a variation of the D' Appolito configuration, which allows for mirror imaging and an improved (horizontally and vertically hemispherical) radiation pattern. It's sort of a "V"-shaped coaxial speaker. This geometry is patented and approximates a true point source; it propagates a coincident, hemispherical wave with outstanding imaging".
