So you would open it regularly to make it full range or make it with the 80 hertz filter. Why not say i will just use it 80 hertz and have the best cap fitted there. I cannot imagine changing my set up regularly. I did start using it with the filter right away because i have an active subwoofer. Still waiting for russian teflon and pasper in oils to arrive. Now i just use the switch to select between two 80 hertz caps. The first one i did install was way better than the original one. i can send you a pair if you like.
Are you going to install them yourself? Can be done but it is a lot of connectors to disconnect and you need a good soldering station and desoldering pump.See my post in the other thread.
This 80 hertz will give better results if you are using a subwoofer. That 80hertz will be physically smaller in such a way that you can fit 2 so you can switchj.
Sincere greetings, Edward
P.s the russian paper in oils are about the seize of my favorite cap now but the teflon are way bigger. The 100nf will fit but you might have to make the wire a bit longer at one side.
