Hi all,

I have a K120 8 ohm cone driver in a small vented enclosure. I bought this second hand as a "practice" bass guitar enclosure. It works brilliantly but gets a bit "woolly" around low E. I've heard that JBL suggested installing in vented enclosures some kind of mounting seal that prevented any leakage of air from around the edge of the driver, thus retaining the integrity of the tuning ports.

Is this so? Are these seals still available? Any help would be much appreciated.

Cheers,
