Last week I purchased a pair of Bose Companion 2 Series II speakers for use with my MacBook Pro and after using them for a couple of days have decided that I can't live with them, so, I'll be returning them this weekend. I'm not looking for speaker recommendations, so everyone chomping at the bit to tell me to get the Klipsh ProMedia 2.1s or the Swans M10s or the M-Audio AV 40s or the Audioengine A2s can save your time as I've already read a ton of like recommendations here and elsewhere, sorry. Since my next choice will likely be an internet purchase, sound unheard, I'd like to understand better what all the specs mean. What I'd like is more information, like does the number of WATTS make a difference? Is the number of WATTS how much electricity the speakers use or does it mean something different? Does the size of the individual tweeters, mids and/or subwoofer make a difference? What about bass ports? What about the speaker cone material? What about the cabinet material? Any help will be appreciated. Thanks!
