I would go with the KLIPSCH!
A computer can only handle one set of speakers at a time.
sony speakers and pioneer speakers are both bad
Purchase a set of Sony, or Panasonic 3way speakers in the correct size and they will sound great. There are other more expensive speakers that also sound great, it just depends on how much you want to spend.
The front speakers are composed of a set of component speakers, a 6.5" diameter with a 3.5" mounting depth along with a 1" tweeter with a 1" mounting depth. The back speakers are composed of a set of coaxial speakers with a 6.5" diameter with a 3.5" mounting depth. It also includes an 8" subwoofer with a 4" mounting depth. If you are replacing the speakers just get a set of 6.5" component speakers along with a set of 6.5" coaxial speakers. You don't need to worry about replacing the subwoofer.
No, you cannot visibly see the speakers. The speakers are set internally in the hardware of the iPod.
Online auctions are a viable option for finding a set of mp3 portable speakers. A site like www.100auctionsites.com is a good place to start. However ebay and regular retailer might offer better prices.
If you're looking for a set of iPod Bose Speakers, eBay provides a wide variety. A set of iPod Bose Speakers on eBay costs as little as $99.95. What a deal!
the shielded speaker is better
The Altec Lansing speakers are great for use sparingly, but as for quality it is recommended a better buy, as that old saying goes you get what you pay for!
Some cordless speakers transmitters are better than others, just bring them out far enough until you could hear hissing and then cut that back a bit.
go with aftermarket speakers, they are cheaper, sound better, and are usually made with better quality material.
