What can anyone say about Quarter Wavelength transmission line enclosure design ?

Hi All,

Just wondering if anyone experienced listening to the speakers based on transmission line enclosure design, as some people swear by it explaining that is the best think you could have once you audition them, as far as bass response \ impact concern. If anyone owned this type of speakers I would love to hear what you have to say and audition them some day. 

Thanks,

Fried, and his IMF(Irving M Fried) designs, got me interested in TLs.  Man; that's been awhile(I'm dating myself).

Bose has used transmission lines many times. Not these inverted horns stuffed with fiber that some call TL's, which really aren't. They have the problem of limited bandwidth and size. It's why the Bose Wave Radio was huge.  Not a technology I personally take too seriously.

Found it! https://sanderssoundsystems.com/downloads/speaker_builder_dec_1980_an_electrostatic_speaker_system_P...

Exactly what I built! Excellent deep bass. Is this the same design you used too Rodman?

@millercarbon- Affirmative. Built three pair of those. Excellent, extended, authoritative, articulate and tuneful bass. The system did a good job of extending the dynamic range of the electrostatics too, relieving them of the longer excursions, demanded by the bottom freqs.

These ARE, by definition, "transmission lines" and have been found wonderful designs for bass reproduction, by the experienced and dedicated. http://diyaudioprojects.com/Technical/Papers/Non-resonant-Loudspeaker-Enclosure-Design.pdf Good stuff, regarding why they work so well, for the knowledge seekers: http://www.quarter-wave.com/TLs/TL_Anatomy.pdf
