Horn Equivalent Circuit

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

this is the acoustic equivalent circuit of a horn system, i think it is a marshall leach jr work but i'm not sure, i want ask if someone know the formulas for the calculation of RAB MAB and CAB  that is the acoustic resistence, mass and  compliance of the closed volume posteriorly to the throat of the horn, i' m planning a simple software that calculates the circuit equivalent of a horn system leaving from the thiele small parameters and constructive parameters of the horn, would be my pleasure subsequently to put in the net this software as freeware. 
if someone has a better outline and preciser, I am happy for improving my software and invite later speakerplans user to test and to simulate data obtained. thanks for the attention. Bye

	Hi LOVAZ. I would also reccomend posting this onto audioasylum.com 'high efficiency' There are atleast half a dozen experts who can talk all about this - even to the errors in the paper which were corrected later.
