Post Subject: 400Hz horns: which length?Posted by tuga on: 11/13/2008

Hello Romy and everyone,

I am going to order a pair of 400Hz/1" tractrix horns from http://www.stereo-lab.de/tractrix.html to replace/compare with a pair of 500Hz TAD-like square mouth horns.
These are to be used initially with the drivers that came with the improperly implemented two way commercial speakers (1" compression drivers, 12" paper cone drivers in ported boxes) that I bought for experimenting. With information I have been gathering from reading the website I have changed the crossover frequency from 500Hz to 1000Hz and recently added a Visaton horn tweeter (that I am currently experimenting with).
From the pictures on Stereo Lab's website, it looks like they make more than one length. How does this affect sound and which would better suit a driver operating between 1000Hz and 12000/15000Hz?

Thanks,
Tuga
