I have a niece that is into music although has no hi-fi equipment, nor am I trying to make some. But I do know I can find some mid-range speakers on the cheap, and I can build a really nice cabinet. There are kits to build your own nice speakers, but the price is to steep so I'm thinking of upgrading a used/unwanted set. Question is -- if I don't know what I'm doing, is this a reasonable project to take on? Easy to replicate the dimensions of an existing speaker, but this stuff is new to me so I'm not sure the impact of different wood, thickness, etc. on the acoustics. Anyone done this or think it's a project worth experimenting with?
