Tangential question, I have a nice audiophile so and no speakers at the moment. I want some speakers for $low that have decent performance. I can build boxes (used to be a carpenter), but need a design and what look like expensive drivers and crossovers. Is DIY speaker construction actually a cheaper way of getting a top notch hifi, or should I just buy second hand?
For a nice tower or woofer box, building your own is usually way cheaper than buying new but rarely significantly cheaper than scavenging or second-hand purchases. There are tons of designs, but in general just build based off the specs of your drivers and the area you'll be placing them and you'll be alright. For specialized types like electrostats, building your own is pretty much the only way to go unless you're ready to drop 10-20k on commercial offerings.
