You should be good for 1.5cuft sealed...then use a nice little converter to get your liters.

 

Thats like 42.5Liters, and Focal is recommending a 35-45Liter ported enclosure. Shouldn't a sealed enclosure be smaller, ergo less liters and if the sub is mounted inverted, then even smaller?

 

Well I used a sealed enclosure with mine, but I do seem to remember that a ported enclosure is the optimum enclosure for the KX series

 

What i can reed its ported on WX series and sealed on KX series

 

I just saw that too. WX is the Utopia level. KX mid, and Polyglass on the lower end.

Polyglass and KX I have owned, and sealed is both of them. I can see where WX is ported.

Forgive my mistake. I misread your original post. You should be good with 1.35 cu ft ported with that subwoofer.

Hehe, no problem.

Hope there is anybody else here that can give me an answer :blush:

 

Greetings!

Depending on what alignment you need will determine vented or sealed for the 33KX. If you want the driver to be basically ruler flat with extension I can send you a vented enclosure design. -3db at 29 hz enclosure tuned to 31hz.

If you want the driver to have punch and drive then I can recommend a 1.35 to 1.5 cu ft sealed enclosure. Inverting the driver is fine and will work in any sealed enclosure between those sizes.

If you want the vented design just let me know!

Nick, you made the same mistake I did, it is a 33WX my friend.

Ok, sorry for my dyslexia!

33WX 45 liters 3" dia port 10 inches long F3 40hz


That should do it!!!

And if you have space, you could try 50 liters - 4" port that is 9" long - for an F3 of 37Hz

I get all kinda replies, but all about the enclosure volumes, and i am grateful that people take their time to answer about that, but as topic, i need to know how many liters the sub is itself

 

OH CARP...my bad. Can't help you there. Nick?

 

Between 3 and 4 liters. Just a guess.

 

The recommended enclosure size by Focal takes into account the airspace that the driver will take up.

i do agree with Schmiddr that 3 to 4 liters should do it!

Marcus,everywhere I looked,it said the 33 "should not be run inverted",even a Focal site..
