Why?
I don't understand buying these sorts of docks. They don't sound all that good, and if you are looking for something that doesn't really sound all that good, why not get a clock/radio dock?
If yo want something that sounds good, plug your phone into the regular home stereo.
I've got a sweet little tube-type dock with 2 speakers. No subwoofer, but the speakers have tight bass that goes as deep as many of the "subwoofers" you see on 3 piece systems. The dock on it was from before Apple borked the 30 pin connector (the first time around, maybe iOS 2.2?). So I just use the stereo plug and ignore the borked video output. It sounds good. Tight bass so you can tell the difference between the bass drum and the bass guitar (and even listen to the fingering technique of the bass player), natural sounding midrange, good stereo imaging when you sit between the speakers, and it gets loud enough to crank it and listen from the back porch. $70 bucks on eBay.
I don't understand these limited usage, bad sounding docks. What are they good for? Doesn't iHome sell some good-sounding clock radios?

Why do they still make these with docks, I don't get it, use bluetooth and everything will work.
Bluetooth sounds like ass.
