8 inch full range

I think this speaker is good for base reflex enclosure because EBP is over hundred.
i need your help to calculate the Vb, port dia & length for this speaker. Actually i want to guide a friend of mine with your help, we both know almost nothing about acoustic physics. As you can see the manufacturer did not provide much information for this speaker :(

What is the difference between woofer & full range?
Better performance at low frequency?
I thought there was not much difference between them :)

On a basic level, a woofer is a low frequency drive unit, i.e. it only operates / is only usable at lower frequencies. It will have limited (usually not very good) output in the midrange and nothing at high frequencies.

Oh! good to know. Here for cheap bookself speakers people often use this type of drivers, without mid range & tweeters.
 
Generally a mid/woofer is designed to be able to extend to higher frequencies because the cone is shaped to allow a controlled radial breakup towards the VC.


This is often achieved by using a 'curvilinear' cone, a non conical shape which is often composed of two radii, (when looking at the Xsection, a large radius at the perimeter and a smaller one towards the VC.


At high frequencies the cone becomes the suspension for the reducing effective radiating area, towards the VC. At extreme HF it is known that in some cases it is only effectively the VC which is generating sound.

Hmm..maybe you are right. it make sense.
But for my next build i'm not going to use their products &
i wouldn't recommend to anyone.
