Best Speaker under 31 inches tall

Replace your fridge with two small dormitory models 18-24" tall. Use some quality spikes to spkie them to the floor. I would then get a few pouds of blu-tak to isolate them form the speakers. You now have a symetrical setup and have plenty of vertical room to set up your speakers. You could still use your Gershmans, but I would recommend using a large sattelite subwoofer system. This would be aesthetically more appealing and having the subwoofer off in a corner would keep the bass off the fridge and hopefully save your eggs from the threat of getting scrambled.
I would reccomend a beautiful pair of Sonus Faber Concertina monitors, a beatiful Walnut and leather clad Italian beauty that would not embarrass any fine kitchen appliance. To add some serious bass to this I would tuck a REL subwoofer of in a corner.
I know this is a lot to consider but it truly is the only way to meld the sonic performance you are looking for (Imaging, soundstage and detail) with a major kitchen appliance. The fridge being the obvious choice and I applaud you for it the oven would prove an obvious hazzard and the dishwasher is just plain to noisy. I would recommend auditioning a few different fridges and seeing which on best compliments your speaker of coice. I would strongly recommend carpeting the front door of the fridge to cut back on any unwanted time smearing reflections.
Bon Appetite

cut some circular holes in the fridge and install high quality drivers directly to the fridge. The volume is large enough to give you deep bass. You could mount the tweeter and midrange up in the freezer and have them in a completely different chamber, very high end ala b&w nautilus. THe random placement of food whithin would break up any internal reflections. I would damp the door and take care to secure anything that rattles. With two full size fridges you could create a monstrous sound and thing of all the storage, you wouldn't have to go shopping for weeks.
