Long time listener/user first time builder. So I bought a pair of Sony Bookshelf speakers. At first I thought there was something wrong with one of them. I took it apart and learned alot. Turns out I didn't have enough power going to the amp, my bad. Once I figured that out. I was like let's build a new box, ya wood working, chose wall nut body and maple face. I'm still on the planning stage. I was wondering about your thoughts on this little guy here. Again when you look at the picture this is a first. And I need a better soldering iron! Found that out last night. $5 dollar aliexpress one didn't work well
I presume the "little guy" is the crossover board.
Is this an off-the-shelf, universal type crossover that you have purchased on-line to use with the woofer and tweeter from your Sony speaker?
If so, please supply a link to the supplier of the crossover board, and also tell us more about the woofer and tweeter (e.g. are they 4, 6 or 8 ohm?).
That information will help us comment on whether the crossover is a reasonable match for the tweeter and woofer combination you are using.
