I listened to the MB Quart S1030 and S830 the other day and they both sounded really good to me. Yawaonline is offering very good deals on these speakers, 50% off the MSRP. Anyone know why? Is the line outdated are something wrong. Its very hard to find reviews on these speakers. But the dealer that had them also had the polk lsi line. I thought the MB Quarts s830 sounded better than the polk lsi15. Any thoughts on the MB Quarts would be appreciated. I mainly want them for music.
