Construction is exactly the same. Find a proven design. The crossover required soldering skills but I've taught that to people in 10 minutes. Here are the main speakers I am working on - http://www.speakerbuilder.net/web_files/Projects/D3/dayton3.htm My current speakers are a center DIII (see above) and a pair of DII's - http://www.speakerbuilder.net/web_files/Projects/D2/d2main.htm As you can see from the DIII diagrams, the construction is really easy. It's a box with a single brace / port flare. Before you glue the front on, you glue in the crossovers. I've spent more time finishing them with automotive paint (Bondo, sand, primer, sand, primer, sand, paint, paint, paint, clear, clear, clear) than it took building the box. If you need smaller, I have plans. If you need massive towers, I have plans. Any of these will easily beat speakers from Best Buy and other big box stores. If you want to go critical listening then you can as well if your budget will handle it.
