I am looking for a very compact portable speaker solution to pair with my Toshiba SD-P2000 portable DVD player. My requirements are: As small as possible to allow for storage in DVD carry case Magnetically shielded (can LCD screens be affected by magnets?) Ability to use as both passive and powered speakers would be a plus Sound quality should be decent, but does not have to be incredible. I'm looking for an improvement over the built-in speakers. So far, I have found two Sony models, SRS-T55 ($50) and SRS-T77 ($90), along with a Wharfedale LoudMan Flat-Panel model ($40) and a Koss SA10 ($16). The Sony SRS-T55 looks exactly like what I'm looking for, according to the specs sheet. It measures 2" x 3 3/8" x 4" when closed, can be used active or passive, is shielded and has a frequency response of 100Hz - 20KHz. Does anyone have any experience with this Sony speaker system, or any other portable speaker systems that may meet my needs? Auditioning such devices can be difficult (Best Buy has the products on their website, but not in the store, for example). Here are links to the products I've listed: Sony SRS-t55 Sony SRS-T77 Wharfedale LoudMan I cannot create a link to Koss's poor excuse for a website.
