Im looking to purchase a pair of low budget but decent speakers, my choices so far are Polk Audio T15 or Tsi 100,Energy C -100 and the floorstanding Sony SS-F5000. At this time I am only able to audition the Polks that sound pretty good,ive heard Energy speakers in the past and was always impressed with there sound. The Sony floorstanding speakers are very cheap and comes with an 8 inch woofer , there also getting good reviews. I know the Sony's will give more bass but will I have to sacrifice overall sound quality ?
