Simple 3.6R XO tweak

Simple tweak who improves the sound to a more open and precise! 

The original XO

Modified XO connection

• Simple connect from the panel outer "Tweeter Attenuator" input port the attenuator resistor with a wire direct to the XO "+" input port!

The simple modification

Electric XO attenuation curves

Electric XO attenuation curves (zoomed)

Electric XO phase curve

Electric XO conclusions :

• "Mid speaker" level will be increased by about 1.5 dB

• No phase jump for "Tweeter speaker"

• Very Small  "Tweeter speaker" level increase

• Still enough low frequency level attenuation for  "Tweeter speaker"

Listening changes :

• Overall higher opened sound image (may requires now a higher  "Tweeter speaker" attenuator resistor value)

• More precise  higher sound

Some impact :

•  "Tweeter speaker" no more fuse protected
