I have built a set of John Krutke's L18/27BFCG http://www.zaphaudio.com/audio-speaker17.html
monitor and just test fitted and taped the drivers down with a basic audition and during playback of cd's it sounded like someone was turning the volume up and down slightly over and over again.
I followed the schematic for the crossover ( including physical layout of components ) but used a combination of x-over components by dayton and some from madisound. I did this to make sure all values were the same including resistance of inductors.
Number of things come to mind that may be wrong.
- damage of components during soldering.
- the fact they were just taped down.
- polarity
I know the physical layout and assembly of the x-over is fine checked it over and over. Schematics are easy. But I do need more of a grasp on the behavior of signals within a circuit. But I think I know enough about this that this up and down of volue is not attributed to simply a faulty x-over.
Just wanted to weed out anything before I started the whole finish aspect of this project. Im thinking I just need to get the drivers screwed down. But had to throw this out there.
