The US version of Aurum Cantus speakers are jointly developed by Kellsie Audio&Video Designs and Aurum Cantus. They are more refined with higher quality components and sophisticated designs. As an example, the pictures below show both Leisure 2SE US version (left) and generic Leisure 2SE (right) for comparison. The major differences are:

1. The mid-woofer used in US version is AC-130MKII with carbon-fiber sandwich cone. It responses much faster and has lower distortion than the poly-cone used in generic Leisure 2SE.

2. The rear port used in US version has flares at ends to minimize port noise. Also, the port tuning is precisely optimized to take full advantage of the quality mid-woofer.

3. The crossover in US version is designed by Kellsie AV Designs US team with 3rd order slope, while that in the generic is 1st order for lower cost.

4. Components used in US version are hand matched within 5% deviation for precise imaging.

5. The finishing of US version is of the highest standard. More layers of coatings and longer hand polishing. The difference can be easily told with photos or in person.
