Sorry but i am not a specialist ,i don't realy understand what it means !!!!

Zilch was referrring to a JBL Enclosure Model number - the 4507 ... box size contains 5 cubic feet of volume - build or get one of them & close off some of the ports to lower the frequency ...
Find more info by doing a Search on this site for "4507"

This is the box Zilch is talking about. it has four ports and is tuned to 40 hz I believe, by plugging varying ports, the tuning can be lowered.

What are the best amplifier to drive a 2231A ( not the more expensive )
Serge
I have a small problem with my 2231A .
When the music is very low ,i hear a little noise ("crackling paper" i think it comes from the spider)
What can i do ?

When I push the cone with my fingers i have the same noise !!!

An where i can find a mass ring ?
Serge
The mass ring is part of the 2235H recone kit (the only kit available for a 2231A recone).
Omitting the mass ring would turn it into a 2234H.
