I have good soldering and wiring skills. I soldered a small chip back onto a hard drive once. The drive still works. My wood-working skills are bad, i.e. never did any woodworking in my life. Maybe in shop class in the 7th grade, but that's it. Which worries me about routing on black gloss finished cabinets. Which reminds me, I have no clue how to transfer the exact size and shape of the drivers onto the cabinets, nor how to do that indent around the edge of the holes (I think it's called a bevel) to mount the drivers flush with the cabinet front.
And the tools will last quite a long time. Screws, disconnects, wire, glue, solder, iron, wick, all that will last a long time, though I tend to go through iron tips quickly.
Whatever works for other people works for other people. If you think you can't build speakers, then go ahead and buy them already built. Some things are better bought built.
This reminds me of my R/C Helicopter experiences. The first R/C helicopter I bought was a Gas-powered Helicopter kit. $1200 investment. Put it together myself. It crashed horribly. $1200 down the drain. But I didn't know what I was doing, and should have bought a cheaper one. The next one I bought was a miniature electronic Helicopter. $400 investment. I got further with that one than I did with the more expensive one.
Moral of this story is to go with the cheap DIY kit first, then move onto the more expensive stuff.
I could have saved a lot of time and energy and bought a pre-built one to learn how to fly it first, but I wanted to get the satisfaction of building it myself. If you crash a pre-built one, you can't take it back to the store and tell them "I crashed this, give me my money back". They'll point and laugh at you. However, if you crash one you built yourself, you can take it apart and sell the parts at half-price, or fix it yourself because you know what went wrong, or what broke.
If you break those expensive store-bought or internet-bought speakers and they're under warranty, you can send them back to the store and get replacements. If they're not under warranty when they break, which is usually the case, then you're screwed. Break ones you built yourself, and you can replace the part yourself because you know what broke.
I've already built a pair of Dayton BR-1 speakers. They were a $150 investment. I did them correctly and they sounded pretty good. So I'm going for a more expensive investment this time. I'll start with 1 speaker and see how it turns out. If it works, I'll use it as a center speaker until I got the money to build another.
