Refresh yourself by replacing the insulated push with a new one! The terminals have also been polished, so you can use it comfortably. A dividing network with a crossover frequency of 1200 Hz. If you cut it a little lower, I think the impression will change quite a bit once you try using it. How about going with making a system? The exterior is smudgy and has a feeling of use.
