TEST OF JBL 2445JPL Compression Drivers with horns

[♔Chello]

TODAY'S GENIUS

I've been thinking about solutions to solve the problem that my new JBL horns are too powerful compared to my main horns.

I saw the solution when I fell asleep:
The main horns are connected in parallel, which turns 8 Ohm into 4 Ohm.

The JBLs were also connected like this - they are 16 Ohm, but became 8 Ohm in parallel.


The solution was simple:
I connected the minus of one JBL to the plus of the other (connected in series), and then 16 Ohm becomes 32 Ohm.

Most "experts" would have surely designed a power-reducing circuit consisting of different components to achieve the same thing, but I am fundamentally against using any circuit if this can be avoided, and I can do it by doing it the way I have done.

Many will say no, but I am sitting here with proof that this works !!!


Increasing the impedance of speaker as I have done from 16 ohms to 32 ohms also has a great advantage:
When a loudspeaker is connected to an amplifier output, the amplifier provides better control of the speaker motion and the speaker has a flatter frequency response if the output impedance of the amplifier is a lot lower than the impedance of the speaker. 

This is most often specified as the “amplifier damping factor” into 8 ohms, rather than the actual amplifier output impedance. If the amplifier has a damping factor of 250, the output impedance is 8 ohms divided by 250, or 0.032 ohms. With such a low output impedance, the frequency response of the voltage supplied to the speaker is very flat and the amplifier maintains good control over the cone motion at low frequencies.


Now there is significantly more pressure on the main horns and the sub-bass, and the tendency for shrill human voices is non-existent.
NON-EXISTING..!

I didn't have the wildest imagination that this could work as well as it does.

Finding some compressor-driven horns that have the same signature as my others would normally have been very difficult; in fact almost impossible.

Talk about luck.

And the system can still be improved by making dipoles for the JBL and Philips horns, which will be the next and final work.
