ALTEC Voix Du Théatre : Partage d'expériences
RE: ALTEC Voix Du Théatre : Partage d'expériences
J'ai contacté Christian Rinselen qui m'a gentiment indiqué quelques informations complémentaires

"it's been a long, long time since we built the blue thunder speakers, so i do not really remember all the details. however, the tractrix horn is calculated to go down to 100, 150 hz (i do not remember, really). frequencies below that are bass reflex (of course there is a roll-off at the lower range of the tractrix horn, it's not a 48 db/octave cut!). we measured the blue thunders to be flat to around 35 hz if i remember correctly. and yes, i am still using them daily, still with the audiom drivers (which are great, but no longer available).

by the way: an italian manufacturer boldly copied the design of the blue thunders and sells his "replica" for € 19'000/piece. Di Prinzio, uses a 15" Supravox woofer, a 2" TAD 4001 mid and a TAD ET 703 tweeter. All these drivers use powerful AlNiCo magnets.

(scroll down to the 3rd and 4th picture).

here's an earlier picture of his speaker where you can see better that they are identical copies http://www.tnt-audio.com/shows/romahe08_e.html
salutations, christian"

Quelqu'un saurait-il simuler le pavillon avant + Bass Reflex ?
