[QUOTE="SkizeR, post: 8703906, member: 633600"] I think your misunderstanding what midbass drivers are supposed to do.. play midbass lol. Let your sub do its job, and let your midbass do their job. Midbass drivers are not supposed to be able to play super low like a lot of people seem to think. That said, if they cant handle 80hz, sounds like an install issue. Sorry, but i haven't looked through your whole log but if they cant do this, I'm sure it has to do with the install. I also know that these have no issue playing up to 1k. These are midwoofers after all (honestly, not the best choice for a midbass application, but that's for a different discussion), but by crossing a 3 way set at 1.5k, it almost completely defeats the purpose of a 3 way. If your DD 2.75" driver has trouble playing below 700hz, that sounds like you have either a defective unit, they ****, or you have insane and unrealistic output expectations of your system. Frankly, the whole midbass thing also points to you wanting unrealistic output unless again, its just your install but I'm still betting on a defective speaker. They unfortunately don't list any useful specs (one reason why I'm not a fan of DD), but they do list frequency range of 160 and up. This most likely means FS is about 160.
