The cabinet volume calculations are executed considering an external resistance of 0.3 Ohm. We are using, if no other data is known or available, the information supplied by the manufacturer.

Please note: the frequency response doesn't say much about the cut-off frequency inside the cabinet! Therefore, we mostly give you 2 examples with dimensioning considerations and an indication, how low the loudspeaker will reproduce.
