Hi Earl,
thank you again for your very helpful information!!
I think i try your second circuit with the l-pad!
I will play around with the value of that 5,3uf capacitor too.
If your crossover simulator has a database-I think the 605 is a 416 woofer and a 806 tweeter.
For your interest i attached a received schematic from an altec N-1500 crossover-do you think i can use the attenuator part (15ohm+25ohm adjustable)with my tweeter?
(Have no l-pad handy,but can buy it on weekend)
Best wishes from germany,
frank
