Speaker Cabinets

dscrobe · 26th October 2007, 09:32 PM

Would like to create my own bookshelf speaker cabinets. It would have a 3-4" woofer and a tweeter. Is there a particular volume of space you must have? Also, I notice that some manufacturers leave about 1" diameter hole somewhere underneath woofer. I am not sure what this hole is if for.

Assuming your post is serious, my advice is to keep reading. A good analogy to you post is that you said you were going to build a car, wanted to know if it needed 4 wheels, and didn't know why other cars have this complex thing under the hood.

If you don't want to learn everything you need to learn, you can follow a proven design and just follow the instructions: http://zaphaudio.com/ZBM4.html

dscobe....the short answer is yes (as Leadbelly points out)...and build something already with a proven recipe (as peter_m points out).

Ouch... What I was concerned about is too high of internal pressure reflections and resonances caused when the cones moves backwards. Want cabinet small as possible.

hi dscrobe,i think the previous posters are just trying to point out that you should do some reading and searching.the fact that you don't seam to know what a port is can be easily fixed by a quick google.most here are really helpful and willing to educate,but a little research on your own will get you a long ways.like a quick search here
