Need speakers that can rock with just one watt? You found da place.

Simulation




Hi J_S,

Above you see 'rought and dirty' simulation of the horn you have specified in half-space (that is, on the floor). With the specified driver it will take you just around 100 Hz 'in room'.

The horn throat you have specified is very large for the given driver. With a smaller throat you will raise the efficeincy a little and also make the horn go a little higher.

Hats off, if you want to turn this horn yourself - it's a lot of work for sure! You may consider either making the horn rectangular which will make it a lot easier to build, or purchasing a 'ready-made' one from StereoLab for instance. They make 140 Hz tractrix horns for different throat sizes at fair prices. The 140 Hz horn from StereoLab will not go quite as low of course.

Maybe someone else will chime in - I'm no horn expert for sure, I have just punched the numbers....

Good luck!

Best regards
Peter
