The D130F woofer was designed for musical instruments. How does it compare to the D130s that were not designed for musical instruments? If I remember correctly, when I bought these (over 40 years ago) they had a copper voice coil rather than aluminum and were designed for high power - but how do they compare sonically with a regular D130? Any opinions?
