weak bass...

[mosfetmaster]

Well,

I have this woofer:

http://www.ciare.com/pdf/catalogo/CW254.PDF

I'm using it in a sealed 56 litres box (20-22 litres net) and I have a very weak bass at low volume levels.
Someone told me that this happens because that driver is conceived for bass reflex pourpose, and because anyway it has a very high Fs to get good deep bass.
So, should I change driver or can I improve the situation in any way?
The box volume seems to be correct even if I would transform it in a bass reflex unit, so I only should add the duct...
What is your opinion about?
Any margin to save the situation?

thanks

Hi!

That someone told you right. This driver is not ment to produce deep bass, but vented box will give you more extended bass then sealed.

I suggest you check this calculator for bass reflex design: mh-audio.nl - Vented System

Thanks. But I see different results with different calculators...so what would be the right one?

It is called a woofer, but it is not.
[Xmax] = 1.35 mm
[Hz] = 0.28
[Qts] = 0.28
A MF driver it is.
For best results, operate it above 100-200 Hz.
