Setting Base PB-22 is a setting base for amplifiers and speakers. The material is made of ebony wood (which is called striped ebony from Southeast Asia). This material is a rare material nowadays, but it is actually used for guitar neck and violin pieces such as guitar pieces, and has a specific gravity of about 1.1, and it has a reputation for its sound quality.
The PB-22 has a unique shape of triangles, which is stable when installed, and the top tip is linear rather than a sharp pin, so the product above has a relatively scratch resistant advantage. It also provides better stability than the base of the pin point support when installed at 3 or 4 points. Of course, it also provides sufficient vibration effect due to pinpoint support (line support accurately)
The PB-22 works great for speaker systems as well as amplifiers and CD players. How to use this item is installed 3 or 4 pieces with a 90 degree angle of the triangle facing up for the bottom plate or under the legs. The top edge can be used either forward, left or right. There may be slight differences in sound due to different orientation, so please check it by yourself and make decisions. Turn the 2 front and 2 back (or 1) in the opposite direction, and the sound will change again. Mainly changes the spread of sound and exhisoning. Please make sure to use the correct application for your device. The PB-22 is relatively cheap, so you can stack the same product on top of two tiers to increase the height, or use 2 with a 45 degree angle upward. Try it!
