In\u003cbr\u003esuch cases, a passive radiator may bring about an improvement.\u003cbr\u003eThe chart below will show you the mass which has to be added to the cone of the\u003cbr\u003epassive radiator in order to obtain the desired Helmholtz resonance frequency in a\u003cbr\u003egiven cabinet volume.\u003cbr\u003eThe passive radiator cone is equipped with an M4mm screw to which you can easily\u003cbr\u003eattach the added mass.\u003cbr\u003eFor optimum performance, the passive radiator should be mounted vertically (with\u003cbr\u003ehorizontal cone axis) This is especially important when a signifi cant additional mass\u003cbr\u003eis used.\u003c\/p\u003e","brand":"Seas","offers":[{"title":"Default Title","offer_id":55627358208385,"sku":null,"price":170.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0921\/9630\/7329\/files\/14821.jpg?v=1777956056","url":"https:\/\/www.audiokit.it\/products\/sp26r-passive-h9946-seas","provider":"AudioKit","version":"1.0","type":"link"}
