To be noted

We suggest to use this wide-band speaker with a passive radiator in compact enclosure of 4L.

The tuning frequency is 65Hz, which provides 58Hz at -3dB.

For the upper band, we suggest to apply a cut-band filter centered at 3600Hz, with a very low Q.

It can be done with passive crossover as shown on this frequency response.

Grey curve: Raw response

Orange curve: With cut-band
