Hi Earl,
thanks for your reply!
Here are the answers.
(1) What sonically bothers you about using your modified crossover ?
Too much high frequency and no magic in the mids
(2) Are you simply seeking an "L-pad" / attenuator control wired into the circuit so that you can determine & adjust for yourself the balance between horn and woofer ?
This would be a solution
(3) Are you getting too much, +/or enough of the top upper octave with the present crossover design ?
I think too much
(4) Are you handy with a soldering iron ?
Thats no problem
(5) Do you have a multimeter than can measure the DCR ( resistance ) of that compression driver ?
Yes,the compression drivers have 10,5ohm
(6) Do you have access to DIY speaker parts wherever you are ?
Here in Germany it is easy to get speaker parts in all qualities.
(7) What types of music do you mostly listen to ?
I mostly hear newer jazz and worldmusic and my girlfriend is listening to classic music.
I have seen the mastering labs crossover schematics but i am not really sure if its work for the 605 because its designed for the 8ohm 604.
Diy would be no problem.
THanks again
frank
