Newbie trying to layout a crossover (Overnight Sensations)

[steelfrog]

Hola! This is my first post at DIY Audio, and coincidentally, my first set of DIY speakers as well.

I've opted to build myself a complete set of Overnight Sensations, which I'm sure most of you are familiar with here. I've already built my three MTM speakers and am happily using them as my front and center channels. I'm now ready to assemble the MT rears. The MTs are assembled, but are missing the XO.



However, I'm having a hard time with the crossover's layout. While Paul gave us a really nice crossover layout for the MTM versions, I couldn't find any that related to the MT and I'm just not experienced enough to do a proper layout myself after several attempts.

Would anyone have one lying around by any chance? If not, I'd be willing to throw a couple of bucks your way if that's what it takes so I can learn from the layout.

Thanks!

Hola,

Not sure what you need help with, the actual layout or the assembly. The layout is pretty straight forward. Start with a board and an input and output side. Place all the components so it looks neat and tidy and remember to separate your coils as much as possible and do not allow the coils to parallel one another. Run every second one on edge and perpendicular to the one it is closest to. Then squeeze the components together to make the board smaller and then trace with a pencil, remove each component and write down where it goes, grab a hot glue gun or some zap straps and have at 'er.

My issue is with that actual layout. Assembly is fairly straightforward, but I'm having a hard time drafting out how I'm going to lay it out. I can usually start just fine, but get confused pretty quickly. Here's what I have so far, and this is just random placement. I'm having a very hard time following the electronic layout to complete it.

Hi Streten, I did see that image in the post you had linked earlier, but the image is quite small and I'm having a hard time deciphering everything.

Biggest issue is that I have a hard time actually figuring out what connects to where, and not the physical layout.

Hi,

I'm sorry, its just so obvious to me I'm cannot explain it well,
you follow the rightmost wiring details, using the component
leads rather than wire as much as possible. The thick black
line is the earth line. The top half of the board (and diagram)
is the tweeter layout, the bottom half the bass/mid layout.
That's what confusing you ?, treat them entirely separately,
inverting the bass / mid diagram so the earth is at the bottom.

/Sreten.

Its presumably also the stood on end components that are
confusing, as the layout no longer looks like a diagram.
