Re: Altec N-1600-A crossover schematic.
It's nice to be able to provide something back to the group. Were all in this together.

Re: Altec N-1600-A crossover schematic.
I've got to hear a 604 one of these days. If the HF is lacking you could try a 1uf-2uf bypass around your 3 ohm 10w resistor. And if that's not enough increase your 3ohm resistor to 6 ohms. It works for me with 811's/511's but may not apply to 604's , may be too much a different animal.

Re: Altec N-1600-A crossover schematic.
The High frequency wasn't lacking, it was more of a mid frequency honk/sharpness. At 5 am I had the cabs open and was adding carpet to the back side of the baffle, It cured what I was after, the sharpness disappeared. I used that thin black stuff that's on the walls. I also put it across the ports and replaced that saggy cloth that was on there. It is very porous and doesn't appear to have altered the ability of the port to do it's job.

They sound like this. This is before adding the carpet to the back side of the baffle.

Re: Altec N-1600-A crossover schematic.
Listening to my speakers last night and I could swear I heard the HF dropping out on the right side. So I removed the cover and checked everything. Found that the lead in wire where it was connected to the loop for the phram screw was hanging on by 3 strands. That made them sound a little better. Also realized that without the loading caps, the screws I was using were steel where the original ones won't stick to a magnet. so I put the loading caps back in. They must be stainless or something. Not sure if that was affecting their operation but I feel better about it now.

Re: Altec N-1600-A crossover schematic.
I tossed together a pair of mock N-1600 crossovers. To be honest I didn't even want to put them in because I was happy with how they sounded. I was skeptical about them being able to sound better And was almost positive that I would be switching them right back out after 10 minutes. There still in!!! I can't believe they are better sounding but they are!!!. I wired in the attenuators and they are set at 1 ohm.

Re: Altec N-1600-A crossover schematic.
I was watching a movie last night and it got to a boring part so I flipped over to the ole FM and was immediately thrust into a 3D sound like I had never heard before. The speakers truly disappeared!!! When I woke up this morning I flipped it on again because Jazz Brunch was playing and it was truly magical. I still can't believe that these crossovers are performing as good as they are. Movies sound a little better than with the old crossovers but for some reason it doesn't compare to the FM sound.
You can check it out if you'd like.

Re: Altec N-1600-A crossover schematic.
Hello friends,
I would like to try N1600A crossover with my Altec 605b's Could someone please let me know the inductor values for -2 and -4 db steps, my calculations give me approx .58 and .36mH.
Regards,
Sandeep
