Well, If you're sure they're not blown, they're either bottoming out because you're overpowering them, or your box is not the best. I'd recommend putting them in a sealed box. even run some caulk inside where every peice of wood meets another, just to make sure it's sealed. If your box isn't sealed well at the edges, or your ports are too big, the speaker will have excessive excursion (in & out movement), causing bottoming out, and voice coil damage. Plus, I just like the nice tight bass from a sealed enclosure. Hope this helps.

Why does ice keep forming in the bottom of the refrigerator

If you are referring to ice forming on the floor of the freezer, it's a result of a blocked defrost drain. Contact Maytag to send out an authorized service company to make repairs. There is a drain kit that is installed at no cost to you.

My Bosch KGU3420GB fridge freezer keeps getting a thick layer of ice in the bottom of the freezer which then 'welds' itself to the bottom freezer draw. Any idea how to fix this?

Sounds like the drain is blocked and defrost water is collecting in the base. Try a full defrost and check the drain hole clears.

Magic Chef Dual temp. wine Cooler #MCWBC77DZC

I suspect the cooler can only actually regulate one of those temperatures and the other one just drags along behind. Perhaps the weather is now warmer and the cooler has to keep the motor on longer to keep cool. The unregulated bottom temperature ends up cooler as a consequence.

Either that or the opposite effect is doing it.

The answer might be to find a 61 degree place in your house to keep the reds.

Freezer up top cools but not at the bottom .

I think you must call a technician to check the air damper control and have an adjustment for the air passage to avoid clogging of ice to the air vent located at inside the freezer section cover.And to check if theres air leakage on the gasket of the fridge.
