They look like speakers containing the full range down firing Walsh driver to me. I remember them being marketed under the OHM brand. Can you give us a picture with the grill off, then I will confirm for you and tell you about them, if the do indeed contain the Walsh driver.
Actually, this speaker, if I remember correctly, has an angled up baffle, maybe a 20-30 degree inclination with the mid-bass attached, and a Heil motion transformer tweeter attached above it, radiating energy to the front and back.
If this is that speaker, it requires special room set up. Place no closer than 4' to a rear wall, and about 2' from side walls. Special acoustic treatment placement would be highly beneficial.
