Hej
Jag har 2 st isophon 12" 30/37A basar som jag tänkte bygga nåt med.
Hittar ingen information om TS värden mer än att Fs är 45Hz, 30 - 7000 Hz, 10000 Gauss och 96000 Maxwell
Vad lämpar sig bäst, sluten låda eller portad
Elementen köptes 1977 för ett par K-25 bashorn
Någon som möjligtvis har data om elementen. Jag har skrivit till LUP Berlin men det gav inget

Hälsningar / Torbjörn

Bara att börja leka med olika lådor i något simuleringsprogram.

Tack för hjälpen. Jag mailade till LUP men den sidan berättade de inget om

Sidan 8: Optimal i sluten låda men basreflex rekommenderas också.

Sidan 24 finns lådförslag.
