The BOSE 901 series 6 with a behringer DEQ2496 will give you a larger sound display than the LSI15's. With the behringer equalizer these bose 901's can go toe to toe with some of the BEST speakers on the market ! http://www.epinions.com/content_105506836100 and http://www.epinions.com/content_4143423620
Where to go after Polk LSI15's
As the new year approaches I'm beginning to get the audiophile itch---something I haven't had in over four years, which is the longest I've gone without the itch. I have a combination of AVA and Odyssey electronics,and Polk LSI15's. I'm thinking of upgrading the Polk's and would like to get suggestions as to the next logical speaker upgrade---particularly from former LSI15 owners. $2,500 - 3,000 range max. Thanks in advance for your feedback.
