What is a good enclosure size for 3way?

abejarano · 3rd November 2003, 07:58 PM

Hi one and all,
My question is how is the enclosure volume given by formulas and online calculators applied to a three way? Is the volume derived from the parameters of the largest speaker used and the two other speakers included? Is it correct to derive a volume for the middy and the tweeter and add all for a total volume? Is it best to make seperate subenclosures for each speaker?
I appreciate and am thankful for any and all comments.

Hi Abejarano,

if you build a speaker, with more than one unit, and the units all have another frequency range (for example: one for low, one for mid, one for high), then all units need a separate part in the enclosure.

You'll calculate a volume for the woofer, and a volume for the mid.
Most tweeters are complety closed, so they don't need a separete part. (if they are not closed, then you'll have to create a separate part in the enclosure as well).

So the total volume of your speaker will be the volume for the woofer + volume for mid + volume for tweeter.

Grtz, Joris
