All three of my kids are home and around, so helping them structure their time and do interesting things is our next challenge. My 13-year-old and I built our first pair of speaker crossovers this evening using Paul Carmody boards for a dinky little DIY kit, "Overnight Sensations." Tomorrow, he spray-paints his little 2-way cabinets, which he glued together yesterday. I gave him the little Parasound half-rack amp "Zamp" that Amir recently tested, which I pulled from service recently. With an amp and speakers, my kid has a simple, inexpensive system he can plug into his phone.
