Polk speakers, 2.5 way design, lower woofers are bass up to 200 hz and upper woofers go from bass region to middles, 2.4 khz. Tweeter goes up to 27 000 hz. Both speakers are tested and they perform as they should, all drivers and tweeters of both speakers are good. Speakers work as they should but they are used, over 20 years old speakers and I cant give you any warranty beyond testing, the price reflects the used condition.
