Any reason why JL chose foam surrounds on the fathoms over rubber?

Still this will not stop me. I am pushing the quest(yeah quest,more like dementia)for absolute saturation.

The Gotham will serve as center channel support(the center speaker will be on tall rubber feet) and flanked by Fathoms. That is the secret plan. Flanked by mains...and by a load of DIY and competent commercial subs.

Any suggestions on how to care for the foam surround? I live in the desert with extremely low humidity.

Foam surrounds have come a long way in the last ten years and we use them extensively in much tougher automotive environments. The newer foam materials have much longer lifespans than older materials that tended to dry-rot after a few years. While I cannot give you a specific prediction of how long it will last in your specific environment, we feel confident the materials used in our subwoofers will last longer than a decade.

Mink oil is not recommended... only the pure distilled essence of hummingbird wings should be used.... I'm kidding, of course: THERE IS ABSOLUTELY NO NEED TO TREAT THE SURROUNDS WITH OIL or any other substance. This could do more harm than good.

As for the service parts support for our products:
We strive to provide service parts for our products for as long as possible, but we commit to providing parts for at least seven years from the date of discontinuation of a product. Being that Fathoms will probably be built for a few more years as they are presently constituted, this will add up to a decade or more. There have been some isolated cases where parts became impossible to source due to suppliers that went under, but we have contingency plans in place now that should prevent these scenarios from occurring.

Hope that answers your questions.

One man who goes by the name of Bob Carver (not a JL employee... ) mentions in the user manuals of his subs (not JL) that Mink Oil is great to treat compressed foam sourrounds.

I have applied this to many subs I have that use compressed foam sourrounds and it works,the drying/deterioration is greatly reduced (compared a treated unit with one untreated of teh same model.



Lets see what Manville has to say.

hi Manville, I asked this in another thread but I guess this is the place to get an answer. I'm sure its been brought up before but I probably missed it. In any case I was wondering why the engineers of the fathom and the gotham decided to go with a sealed design over a smaller ported design. I realize the most obvious reason was to reduce the size, WAF etc... I'm wondering if it was also a concious decision for sound quality as well, and if so there seems to be people on the side of the fence that say sealed vs ported sound just as good, and those that think sealed sounds better than ported design. I realize you might have to get back to me on this one but I'm curious as to what the opinions are of your engineers on this (as I know you make ported and sealed boxes for car audio).

edit: I should clarify I'm not trying to start a flame war/argument here, just curious for myself so perhaps a pm reply might be best
