Introduction and details from Srajan Ebaen // 6Moons:

Qualio IQ via 6Moons

They look very similar to the Wolf Von Langa line of speakers.  So similar that WVL should take notice.  The WVL line uses field coil midrange and woofers however.  WVL makes fantastic sounding speakers.  While they look similar it seems both companies use some different approaches in design and drivers beyond the shared Mundorf tweeter.  

For those interested in Cube's Cube related efforts there is mention of a new widebander combined with an 18 inch woofer. Photos of two renders are on page 4 of Srajan's Qualio intro, linked below.
