The material used in our poron foam kits has been carefully selected to provide the best acoustic upgrade for your board.
Our plate foam is made from extra soft, slow rebound poron. This material is optimal in thickness and density to provide the cleanest, crispest notes with any switch you use.
Our case and PCB foam are made from very soft poron, which has a higher density than our plate foam. This increase in density is much better suited to reduce vibration, decrease hollowness and pinging, and eliminate reverb within the keyboard.
We design our kits with customization and modularity in mind. Our Q Series kits include both the PCB and case foam. While similar, each provides a distinct benefit when used separately. Used together and their effect is increased.
Plate Foam - Installed between the switch plate and PCB
PCB Foam - Installed directly under the PCB
Case Foam - Installed in the bottom of the case
I just built up a Q0 Plus with this foam, and it's really great. The Q0 comes out of the box without foam under the PCB. I used the solid foam and placed the insulation layer that came stuck to the underside of the PCB under it. The plate foam fits really well, and maybe better than the original stock foam that came with the Q0, and I was able to use it to get the sound I wanted. I also like that Keyboard Kustoms includes all the different foam pieces so you can make it sound and feel exactly the way you want. One thing to note is that like on many other Q series boards, if you install both foams under the PCB, the PCB is going to sit on the foam and the gaskets on the plate are not going to do a lot. It makes for a totally different typing feel and sound if you like that feel. If you put in either the solid foam or the foam with the cutouts for the switch sockets it will still have the bounce you would normally see on a gasket mount board. It does change the sound, so you can experiment with it to get it feeling and sounding exactly the way you'd like!
