This speaker was designed and built for a friend who likes OB's. And the speaker pair had to fit into his 2008 Audi for transport, so I decided to name the design the 'Audi'.
We settled on a modified H-baffle for the bass section and a segmented wire-stator ESL panel. The overall dimensions are 66"H x 14.5"W x 15" base. The triangular base forms the H-baffle and is removable.
The initial plan was to use a Peerless SLS 12 woofer, which would have given deeper bass, but we opted instead to break the rules for OB and use a low-Qts Eminence Kappalite 3012LF for optimal blending with the ESL. Obviously; this compromises the low end but since my friend will use separate subs in the system, the woofers here only have to play in the mid-bass region.
Below are a video of the new speakers playing at the 2018 Carverfest retreat in NC, and a few build pics. Enjoy!
