My brother is looking to replace a front pair of Bose speakers in his home theater (A big step foward, of course). His budget is $200 - $400. Right now, he is considering the following: JBL Northridge E30 Cambridge SoundWorks Newton Series™ M60 Cambridge SoundWorks Newton Series™ M80 Boston Acoustics CR75B Boston Acoustics CR85B HTD Level 3 HTD Level 4 Polk Audio PLK RTI4BK Polk Audio PLK RTI6BK Infinity INI ALPHA20BK Axiom M3ti He doesn't want them to be bigger than 15" inches. He wants them to be able to sound great with both music and movies. He will be matching them with a JBL center channel and with Boston Accoutics surrounds. While I would think that a pair of JBLs would be a great match for that center channel of his, I am not sure about consistency between brands and the correctness of that assumption. He also listens to music in straight stereo (no DSP modes that use more than the two mains and the sub). His music/movie ratio is 50/50, so if some of these are really a lot better for music, he would probabably be willing to compromise the matching to his center channel just as long as pans don't sound completely out of whack. His sub sucks, but living in an apartment, he isn't going to be looking for a setup to play deep bass at high volumes anyway. On that note though, decent response at lower frequencies (at least in the context of bookshelf speakers), is a consideration as well. All advice is greatly appreciated.
