Post Subject: Midrange clarificationPosted by horny on: 12/23/2007
Thanks for your quick reply. I have been to assistance audio`s website, however was unable to find such model, but is possible they just disassembled the tweeter or whatever.
This is really interesting news, about their violin reproduction, me too would like to achieve as good as possible violin reproduction without spending a fortune on exotic or vintage drivers.
Of course, I don`t consider 700-2400 a wasteful use of a horn, I just thought of a little higher crossovering. Right now I am listening (God forbid !) to a 5 inch paper midrange coupled
to a 60 cm diameter (270 Hz) rounded tractrix horn, without a backchamber (shoot me), mated to a LCY 108 ribbon with a modified (by me) totally flat ribbon and to 8 inch paper woofer
in a transmission line (with the same effective diameter throughout as the driver itself). All drivers wired with the same polarity, crossover points at 600 and 9000 Hz, bass and tweeter
second order (electrically) and midrange only one series cap. The sound is warm and involving The reason I made my own flat ribbon foils is I hate the sound of corrugated ribbons, this is also the same reason (among others) I predict Raal will perform excellent. This week I am moving on to a bigger system with a 93 cm diameter rounded tractrix horn and 60 cm midrange tractrix horn in search for the higher efficiency and better sound. I was considering Beyma aluminium 2 inch compression driver (Beyma CP755NdAL) or Radian 950 PB, they seem quite promising, but will start with a cheap P-Audio WN 73 first (all crap, I suppose to the elite folks). Only when I`ll get to know those cheaper drivers, will I be willing to try (if money considerations will permit) anything better and more expensive.
