I built my 1st DIY when I has 12 years old, my son built his 1st unique design at 4 1/2 only help I gave him has soldering wires to drivers, seems hes in the know;) Glad I have someone to take over KCS when Im gone...His loudspeaker used a pair of Fostex fe126e in cardboard tubes he added wool dampening, used the right port size without any help, heck I didnt know he was building them till mostly finished. He wraped the outside of both tubes with large amounts of brown packing tape this killed the cardboards tone allowing his little speaker pair to sound very good for what it was. 1 of my audio friends wanted a pair so we used veneer instead of paper tape on tube he still uses them daily. So I would say if a 4 1/2 year old can do it maybe you can too.
