DIY 5KHz Smith horn

A picture says more than thousand words.

I have just had the time to do a rough test driven by my laptop, no amplifier.

First result is the 2405H driver, second result is the same driver with the smith horn.

Work drawing.


Used JBL's dimensions for the conversion from ring to circle.

I might just have to build me some of those

Here's a better measurement.


The HF extension looks good, so there must be hope.

Hope to be able to listen to them next week.

Hi Johnny
Could you please repost the plans as I can't read the measurements.
What is the driver pictured 075 or 077?
Thanks
Michael
