Are there any good near field DIY speaker kits out there? I need to replace my computer speakers and I want to build something instead of buying some Altec Lansing thing. The speakers will be powered by an Onkyo reciever. I would like a musical warm sound with good bass responce down to about 60 to 70 hz in room. Anyone know of anything? The point in this is not to save money but to gain experience. Thanks. Edit: is there a rule or piece of software that I can use to help me place the speakers if I do decide to build them?
