Maybe some servo will help. But most probably in finished state servo solution will cost more and SPL that you already have is enough for anyone from your target audience.
Have you seriously worked with focus groups regarding these subwoofer shapes?
It's interesting, because I can't really remember even few subwoofers with "non-cubical" design.
Maybe something with corner placement and DRC will be useful also. Like Atlantic Technology 10 CSB, but better.
With regards to focus groups, There was done some research and surveys initially that helped guide a number of design choices. But the work on understanding the market still continues now, as we have an active test pilot program where people can test pre-production versions of these subwoofers in their own homes for free. This gives a lot of valuable feedback both on form factor, finish and of course sound quality etc.
Feedback from forums like this is of course valuable and interesting as well.
I have briefly considered a corner thing as well, not anything concrete planned. And yes, the current SPL will be enough for many. People who were previously 2.0 / high-end purists who only had a pure stereo setup are now slowly becoming curious about subwoofers, understanding that it can add another dimension to their setup, if integrated properly. And for most music you will have to play very loud to run out of steam even with the 10" version. Also, some of course already have very expensive gear, so they're open to purchasing two as well. If the main focus is maximum SPL for movies, there are other subwoofers that will be a better choice. But if you want a high quality subwoofer for your living room where you are limited in space and WAF, these subwoofers will still deliver quite impressive sound pressure even for movies, and as far as I know there's nothing else like it out there.
Next week I'm loaning a 10" version to a guy who has a dedicated cinema with 32(thirty-two) 10" drivers - but now he wants something invisible to add fullness to the system he has in his living room. Different needs, different products.
