Bass Reflex Enclosure for Beyma 10BR60

[-_nando-_]

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

 

[Notax]

Vb=50 L
Fb=41.5 Hz
Dt=100 mm
Lt=190 mm

Humm, what means FB, DT and LT ?

FB of the 40 liter box in the datasheet was 38Hz




Thankss !!!

 

[Notax]

Fb - tuning frequency of bass-reflex
Dt - equivalent diametar of bass-reflex tunel
Lt - lenght of bass-reflex tunel

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).

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

Wool. And no, no discount.

@Nando, did you ever find a design?
