SPEAKER FANTASY

I thought my project of making a baffle horn was unique.
I was wrong.

Tannoy made one like this many years ago:
There are also several transmission lines along with horns.

   



Here are some other ideas - there are a lot of clever people out there.
I am fortunate to have a background as a machine carpenter and machine mechanic, and have 2 workshops with machines and equipment.

Chello. Another great article.
Whilst I was selling Calrec UK Condenser Microphones, Calrec were testing a Tannoy Dual Concentric speaker in an IMF Transmission Line cabinet.
As we were supplying the BBC (BritishBroadcasting) with microphones, they asked if they could test the Tannoy-IMF speaker.  
We arranged an after hours demonstration at BBC in London Studios where they played back some recordings from that day's live music sessions which did sound excellent.
The BBC engineers stated they thought the Tannoys sounded a little bright but then they explained that their own studio speakers did lack top end so they always falsely boosted those frequencies, so the Tannoys-IMF were in fact correct and a very enjoyable evening for me.

Thanks for your responsive article - extra informative, as always.

Both Tannoy and IMF are ground-breaking pioneers, who we can learn a lot from studying - even today.
