Title: Re: Bentwood horn for imperial Post by buzz on 08/06/07 at 03:57:42 Thank you Steve! I guess now I have another project to finish... ;) A horn of this size has what cut-off frequency? Around 600 hz? |
Title: Re: Bentwood horn for imperial Post by Brian on 07/25/10 at 00:44:53 If the divider template were left in there, would the frequency balance change? I have read that those old multi-cell ALTEC and Western Electric horns achieved two things with the cell structure. The dispersion was better because some of those dividers curved outward to direct the sound to the side, but also because each cell had a small mouth it carried or amplified the highs better than a single large mouth could do. The two mouths formed by a single lateral divider are of course not so small as those of a 15 cell Mirrophonic or Iconic horn, but would they not emphasize frequencies in the middle of the treble band more than the single mouth? Whether this is good would I suppose depend on the usual variables of room, equipment, and listener preference. |
