DBO, Dynamic Bass Optimization

Anyone know anything about this from JBL?

Dynamic Bass Optimization (DBO) - The rear two channels this amp includes DBO which provides variable filtering with adjustable "Q" below 100Hz, far beyond conventional "Bass Q" circuits, by allowing the low-frequency output to be optimized for specific subwoofer applications. Frequencies below an enclosure's tuning frequency can be attenuated, preventing damage to the subwoofer and allowing the amplifier''s power to be better utilized.

"

Dynamic Bass Optimizer™ (DBO) is a new approach to enhancing lowfrequency reproduction in a vehicle.  Conventional bass boost controls add bass at a fixed frequency and cause the amplifier to consume considerable power. DBO conserves valuable power at the lowest frequencies and allows you to adjust the level and “character” of the bass sound, instead of just the amount of boom."

Its NOT a subsonic filter....think about it....filter!     Its a nice way to "tune" the low end. Different vehicles have different characteristics. I can't imagine haveing the center @ 40cycles.....I don't care what kind of subs, and enclosure your running. Depending on your setup, start with your center at say 60, wide! Move the center up or down, more than likely up. then tune your Q. Move wide towards narrow.

Once you get it figured out.....youll love the feature. and remember.......its just my opinion. 

i was just comparting 2 different JBL amps, unfortunately i cant afford the model that has DBO - i was just seeing if it would make that big of difference.

Thanks

Well, it is for my girlfriend who has a Sony.  But she may upgrade soon
