Impious

It is.

I'm not sure I'm following what you're trying to do. If you're reconing the subwoofer into an 18", then why do you need the e12a cone and coil still, and why are you worried about attaching a new surround and spider to them?

Yup...the DCR will almost always be lower than the nominal impedance (the only exception I know of is Resonant Engineering, who's "dual 2ohm" coils have an Re (DCR) of 2.4-2.6ohm). Resistance, the DCR, is constant and does not change. This is what you measure with your multimeter. Impedance, the nominal 4ohm rating, is not constant and will fluctuate based on frequency, the enclosure, etc. This is why the impedance is called "nominal", because it's sort of an average of what load the subwoofer will present to the amplifier throughout it's intended bandwidth. Anyways....those SW8200's have me seriously interested. I really would like to try one out.

Two different things. Mat deadeners/clay/lead shot in epoxy ( ) = mass loading. They don't do crap for the soundwaves, but they add mass to the panel and reduce the vibrations and change the resonant frequency of the panel. Absorption/reflection/diffraction of sound waves = barrier loading. This is the foam and deflex pad products. They don't do crap for resonances. You can (and should) use both....line the enclosure with something heavy to reduce vibrations and resonances, then use foam/deflex pads to absorb, reflect and/or diffract the soundwaves.

Not all of us have only parents/significant others to deal with. There are certain things my children shouldn't be subjected to quite just yet

Werewolf's posts alone make it worth your while.

I'd never heard that information before? Where did you hear it? Sure you're not thinking of the RF units?

You're right...your new avatar doesn't do it anymore. Now if only we can get Kent to change his avatar or sig aswell

Use IE That's what I've been having to do It doesn't do it in IE, only Mozilla

Commonly used approach is to just use non-hardening modeling clay.....but I suppose if the lead is heavy enough and would stick well with the epoxy to the kickpanels...I suppose that should work. I don't know, off hand, how much heavier lead shot is per cubic inch than something like modeling clay, or how much more/less expensive per ounce/pound.

They do rape you on shipping. However, I live within 4hrs of PE...so I automatically get "free" overnight shipping since it only takes 1 day to arrive :

Off to bed boys...
