Many thanks for all your kind responses.
Speakerbits has two versions of refoaming instruction. The instruction for 30w100 did not mention anything about voice coil shiming while the instruction for the 30w54 specified that shimming the voice coil is essential. I've emailed speakerbits about this but haven't got any reply yet. Any comments on this, please?
