Tvad, I was mistakenly thinking of the other speakers in the Planetarium series that required the Swarm sub system. Now that I have referenced the link I see the speakers you referenced were originally a one off made as a special order for a customer, but are now part of the product line.
Since I've never heard them I can't comment. The down firing subs seem like an interesting idea overall and a more than suitable alternative to the Swarm. Personally, I have an aversion to subs, not just due to space constraints but I don't place a heavy emphasis on deep bass. Having originally been a long time Spendor user the mid-range is what attracts me to a speaker. In the Jazz Module case the 32hz rating and adjustable bass port provides enough bass for me.
