Tapered Wave Tube with Damp Duct(TWTD) for Alpair10.3, MAOP10, CHR-90

[sridip]

Officially called a "restricted terminus”. It provides mass-loading which adds another low pass filter in the design, allowing for less damping and more fundemental to reinforce the bottom.

So this design should ultimately aid in extraction of a better low end...

Brother just one clarification
the original Sibelius speaker has a narrow duct while your design has a much wider duct ... any difference in the design...

Yes, Sibelius uses a special driver, has a narrow duct area, short duct length, and unknown sound absorbing material.

DDVP has a larger duct area, longer duct length, and less sound-absorbing material.
