There is also a discount for CI version, but not as hefty as $100. If we base the retail price purely based on some pre-determined mulitple of cost, H550 does not deserve a $100. A more reasonable discount will be $30. But in the case of finished subs, I have been used that as an alternative to offering discount on H600-based FV15HP or F15HP. Since you have asked and to go with the holiday spirit, we will offer a bit more disocunt on H550 CI kits. It still won't be as hefty as $100, but it will be more than what it is now.
