In the Thread: Eventually - a reasonable midbass horn from GOTO
Post Subject: Double driversPosted by ygoh on: 2/17/2008
Romy,

I'm new here, and I have read your posts in the forum.  I have some questions that relate to this post of yours: 'The midbass horn is a pain in ass, a big pain!!! The GOTO-Jackson horn went for the very noble small throat size – something that I advocate for a long time and something that horn public does not buy yet. Sure the horn’s length is the punishment in the case of small throat size but it is what it is and if you do not like it then use direct radiator in bass-reflex enclosure. I do not support the GOTO idea to load two drivers in the same throat. I believe the idea is very moronic as it compromise unanimity of excursion.'

1.) Why is it that you do not support using teo compression drivers in the same throat?   Is the distortions increases, such as wavefront distortion?

1a.) Is the 2nd harmonic distortion also increase with two compression drivers in the same throat?

2.) What are the main reasons of using two compression drivers at the same throat, beside shortening the horn's length?

3.) Do you agree that with using shorter (mouth dimensions is unchanged) horn will not decrease the 'loudness' or efficiency, as efficiency does not depend on the length of the horn, but efficiency depends on throat's area and the drivers itself?

4.) Do you also agree that by shortening the horn, you loose lower frequency?  Another word, the lower cut off frequency increases?

5.) In your opinion, what's the best shape, for the least distortions, bass horn?  tractrix, exponential, or conical?   circular or rectangular?

Thank you
