This cabinet technology hasn't received a patent yet, but they applied for it. These Barefaced cabinets are already in production, and the company are interested in retailers and resellers. It's already black and green too.
I wonder how well this cab would work with the new Celestion speaker that's custom made for the upcoming Kemper Kabinet. CK said the speaker itself would be sold separately, when the time came.
Barefacedaudio has a good Celestion speaker selection, but I'd want the new Kemper Kone speaker.
