N1600 crossovers for my 604Ds

I'd recommend that you measure them, and build a XO...
Don's site is a wealth of info, and he's very generous with his advice as well. He helped me a ton with my 604E.

I measured them...they're both 15"...

...and weigh a ton.


DCR on the LF drivers is exactly 11.0 and the HF drivers are 8.0 and 8.1.

The alchemy of XO design is fascinating to me. If I didn't have so many other things tugging at my coattails, I could see myself getting lost in it learning as much as I could about it.

I'll say this. Once you get those baby's all set your gonna be very happy. Wish I was of more assistance but I've only had the opportunity to play with the half roll surround sound of my C's. I'll say that when I first got my setup and one was a C and one was an E they were worlds apart on their sound. I thought there was something wrong with the E. It was an extremely costly mistake to send them to GPA to have them looked at as they came back sounding the same. I told Bill the E didn't sound as good as the C and thought it needed a phragm. I found the new phragm in the C when I looked. It wasn't the phragm at all because before I sent them I could turn the attenuator in the E's crossover and hear it changing. Between one running a N1500 and the other running an N1600 plus one being an accordion surround and one being a half roll surround there was a definite difference in sound.

I recommend you change the 16 uF cap in each N-1600 . Then if you do build new XOs you will have a base line to compare to.
The old caps are in cardboard boxes with a pair of wires coming out. Cut these wires very close to the box and splice them to the new 16 caps.
Dig out the old caps to make room for the new ones. If the new 16s are tight, or too large, sub two 8 uF caps in parallel . If you want to repot the XOs you could use candle wax.
