SP1022 had a bigger magnet and hence lower Q. Otherwise it was the same as the SP1014, including the 1" voice coil. For this reason the magnet was very inefficient as the 1" pole piece was saturated. On the plus side this meant that flux modulation distortion would be lower.

The standard 4th order Butterworth high pass bass vented box alignement needs a lower Q driver than the corresponding sealed box 2nd order Butterworth high pass design.
