Thumbs up Bass Reflex Enclosure for Beyma 10BR60

Hi !!!


I'm here to ask you experts, how should I build the 10BR60's enclosure !



My objective is achieve a very smooth and tight mid and bass, but also clear!

I can make use easily of 55L, but it can be less if it's better.


The dataheet of 10BR60 shows a response graph with a "Bass6Pro" cabinet, that consists in a 40L, Fb38Hz, bass reflex. There's no other information.


THIS is the datasheet take a look please !



Thank you very much !

urrgg.. I said the 12LX60

..well if it MUST be the 10BR60..

to get a fairly flat in-room response to about 24Hz will require:

a box volume of around 3.3 cubic feet

and a vent around 8 cm in diameter and 16.5 cm in length

AHm, but the 40liters was 38Hz of FB, 50 liters should be tunned for lower frequency, shouldn't!?


Diameter is like this or that!?


Sorry about the fool question !



ANother thing, I'll fill inside the box with cotton or something like that, should I discount in liters it's amount?



Cheers !

Theoreticly. In real, its not just like that.

First. If you have rectangle (a*b) shape of tunel than you calculate half-diametar (Rt) as Rt=sqr(a*b/pi).
