It appears to have more features, so that would make it worth the higher cost - if you need them. Also, it looks fairly nice, while the FBQ is downright ugly. That might be worth something, if you feel the same way. It might also be a better choice for full-range use (you didn't say what you were going to do with it).is it worth a higher cost.
Thanks Wayne, i`ll order the dbx tomorrow ( have to pay 500 USD, it cost 1400 USD in Norway), and if i am lucky i`ll getting borrow a pro RTA at the recording studio ( the seller)
