You can tune the BR/horn design to 35 Hz, but it won't be as efficient as a tapped horn of similar size and shape, a TH can be as much as 6 dB more effecient (per driver) than a BR of the same Fb.
Also remember that lower tunings reduce efficiency, so the relative efficiency of the horn in the 60-160 Hz region where it works makes the lower tuning seem like even less bass.

Can you link up a few th horn designs. Thats have proven efficiency down to 35hz that you know of

This one has proven to work very well:
Keystone Sub Using 18,15,&12 Inch Speakers

Josh Ricci's Othhorn
The Othorn tapped horn
and Gjallerhorn go lower, but are larger, though the flatter shape may be more what you are looking for.

My opinion is that the tapped horns previously mentioned in post #13 sound better, go lower, and have more output per truck space than the scoop designs I have heard.
