Totem Model 1 vs Totem Arro

These two Totem speaker models had more or less the same price, and it was natural to choose between the two when one was interested in the Canadian brand.
The Arro is still currently on Totems catalog but the Model 1 is only available on the Signature version, much more expensive.
I have the Arro (love’em) and I wonder if the Model 1 is superior, specially in the bass quality?

Does anyone have any experience in comparing these two models?
