    Project should indicate NOT a ZOB, but a custom built OB with the Dayton Audio 8 inch FR driver. Includes three GR Research subs, but any of the the 8 inch subs that can reach 200 hz should do fine.

    This is an open baffle design which results in phase cancellation in the bass frequencies. The effect is a 6dB per octave bass roll off from around 300Hz. This why boxes are used – to stop the rear radiation cancelling the front radiation. Open baffle can be used for mid+ but with appropriately sized baffle. However room phase cancellation remains an issue.
