no contest between a KG4 and a Forte none zip nada not in any way go for the Forte. dust cap on the passive has no impact if it is dented it only needs to be air tight. Amy small holes tears or lifting edges can be repaired with a few dabs of white wood glur it is that simple you are laughing. You should slap a metal grill over the passive anyway to protect it but they will face the wall you will never see it so do you really care. Leave them alone and don't worry. Congratulation on your find

Thank god gravity has no bias. Rotate your woofers they have been sagging just as long as the passive units have. Every ten years is a good time frame to flip them and this will prevent the suspensions from becoming distorted. Leaving them longer can result in stretching your suspension well past its range and you don't want to do that. A small dot of nail polish on the frame will allow you to identify your flip point. Best regards Moray James.

you are wrong they have sagged you just have not noticed it, not much escapes gravity. I imagine that there are a number of climatic factors envolved with the process of sag but it is normal and companies such as Altec and JBL used to recommend regular rotation to insure that drives were kept centred on their suspensions. This is a normal process, rubber suspensioms can sag too just not as much. Drivers in long term storage must be properly rotated or they will be ruined. Best regards Moray James

I am just wondering if a Chorus woofer would work any better in a LaScalla with respect to bass extension. A bud has both speakers and I was curious as he is attempting to squeezr a little more bass out of the LaScalla. My gut instinct is no but I figured that I would ask the guys with the experience here. Bob C's cast basket woofers might work a little better than stock but some work would be required to make them fit in the dog house and I am not sure it the cost would be money well spent I

did you really think about this? This is not a tire. This is a weight on a spring all be it a distributed spring it cannot help but sag to some degree over time. Read what said there are a number of factors which will come into play and your passive may well be very happy where they are but sure as god made little green apples they are not where they were twenty years ago. If you care to look into Altec for example you will read over at the JBL Lansing Heritage forum accounts of the suspension dope

You ca also reach Freddy who is the "Keeper of all things Karlson" at fullrangedriver dot com. Please contact Freddy he will make sure the information is stored and also posted on the Karlson forum for the world to see. Thanks and best regards Moray James.

pretty sure that this has not been posted but thought since I have now it I would post with a title that could be found on a search here. Best regards Moray James.

Just got this today. Best regards Moray James.

The proper service adjustment is very simple. Rotate the passive (and your woofers too) 180 degrees do that every ten years and you won't ever have a problem. Best regards Moray James.
