[QUOTE="Ampdog, post: 64349, member: 144"] Unfortunately mostly negative replies from me. No, you cannot assume that the Fs is 28Hz, particularly if the 28 - 200 spec does not include at which loudness (dB). It could be some 35Hz. One can determine the T-S parameters fairly accurately with a signal generator, scope and sensitive scales, but the procedure is too long to include here. You say the loudspeaker is active; then there must be a plate amplifier somewhere. If this operates on the motional feedback principle, you will have to be careful about designing a new enclosure.
