WHT History
WHT Designer Mark Mozgawa has always been involved in the making of high quality PA, instrument and studio loudspeakers. Previously employed as a musician he has had the advantage of using countless different types of loudspeakers on stage and in a studio environment.
"In the midst of one tour my speaker box went missing during transport. The sound engineer came to the rescue and lent me a rather huge PA box called a "J Bin". I had used horn speakers for my instrument a few times in the past and I knew that horns were faster and more accurate than ported boxes but nothing had ever impressed me as much as that "J Bin" box.
The difference between ported speakers and that "J Bin" was enormous. The sound was significantly clearer and the response was much faster. Just a slight, sensitive touch on the string and the notes were out of the box in microseconds.
No sound was left bouncing inside the box. There was simply no comparison, the "J Bin" was a big winner here. This particular, if accidental experiment made me realize how slow and muddy the ported boxes can sound. Eventually my speaker box was found but at that point I just couldn't go back to the original boomy, awkward sound so I convinced the sound engineer to let me use the "J Bin" till the end of the tour.
Next tour started in three weeks and by that time I had managed to build and bring my own "J Bin" with me. It was based on 2 x 12" Celestion drivers and a smaller design with a folded horn. I was able to do some modifications to the speaker box during rehearsals, and used the opportunity for trial
and error. Towards the end of that tour which saw me fine tuning my first scoop speaker, I had removed the folded horn from the inside of the speaker box and from that point the speaker was sounding ideal. The fine tuning went for the next two years and in 1980 I had my final design.
