BLH for physically deep speaker?
 
what are practical & easy to build ways and aspect to deal with a case of deep 10" coaxial speaker when simulation says only 4 liters chamber? This ~68Hz fs driver doesn't see to like much chamber in AJ-Horn.

---got a reasonably pretty sim but not sure if cculd be built simple --? I don't know if this proposal is practical but might be less boring than a reflex
