About the Designer:
I get bored, love to build, then sell, then build something else..
This is clearly not the right description for this build. Looks like it was duplicated from the previous entry somehow.
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.
