Thanks for the video link.
Interesting that they and you both felt there was a need and market for such a product.
I am also a fan of the veneer and it looks like the walnut would match my Fritz speakers perfectly pic here [https://postimg.cc/D86qKGzH]
I’m not a deep bass person. The Fritz don’t REALLY need the subs but they do help sometimes with the soundstage.
But my little sealed ADS l400’s and sealed Spendors can benefit from having them on.
