12" Beam Blocker (4" Dome)

12″ Beam Blocker (4″ Dome)

$19.72

This one is the most popular. Chances are good that this is the one you need. (Unless you feel like you have an extreme amount of treble, in which case you might try the 5″ dome. But this is the one C.J. recommends.)

The Beam Blocker is a simple device that is installed between the speaker and the baffle. The dome shaped diffuser prevents point-source high frequencies from beaming directly out of the cabinet to create that ice pick sound. Instead, they are diffused evenly in all directions to blend with the lower frequencies which tend to radiate in a wider pattern.

The Beam Blocker allows you to make use of speakers that have a tendency to be beamy, harsh, or generally unusable due to their extreme high frequency response. The idea of using a diffuser is not new. Many performers including SRV were known to have applied a patch of duct tape on the grill cloth directly inline with the center of the speaker to block the beaminess. The Beam Blocker performs that same function while diffusing the high frequencies evenly in all directions.

Here is a video by Rick Fass, which shows some very helpful information about the Beam Blocker, including how to install it. (Try to ignore the speaker brands in the video. Your setup will sound much better with Weber Speakers.)

    Installed this on a custom built oversize 1×12. It diffuses the treble perfectly, resulting in a consistent sound throughout the room. I have a custom Atlas cab on order and have already ordered my second.
