Default Apha-TL questions


First:Thanks for Dave and GM that I could get to know about this theory!

My quesions:
- did somebody listened (experienced with) this kind of speakers? I would like to know how is the sound compared to a "classical" design?
- is the the fiber glass the same used in building for heat insulator?
-the open end of the line is forced to the floor or to the front?

You're welcome!

It really depends on what alignment is chosen and the type/amount of stuffing used. If both are constant taper (straight) tuned to Fp and use the same stuffing material/density for a given driver, they should sound the same. Most of the 'classic' designs I'm aware of though are reverse taper, being more an ML-TL than TL. These will have more gain down low than a straight TL.

Yes, though there's various 'R' values available, so stuffing density will vary depending on which one used.

I prefer floor or rear loading if near a boundary, but front works too. It just doesn't have as much gain as the other two.

Loud is Beautiful if it's Clean! As always though, the usual disclaimers apply to this post's contents.
