Since SVS's own product page hadn't bee linked to yet, here:

SVS AS-EQ1 subwoofer EQ

I emailed them and asked a couple of questions. I wanted to know if they planned on releasing one with balanced connections (despite the limited benefit), and if the PC connection via USB would allow firmware updates. No, they have no future version in the works with balanced connections, and yes, they plan to make firmware updates available on their website.

Having no balanced connections means I'll have to buy new sub cables, and I won't have the cool clicking when I connect them, but I'm still interested enough in this product to pull the trigger, I'd say.
