Hello Rui,

For the record, I looked up the Axiom AX500A sub in the October 1998 Audio Annual Equipment Directory (I was an editor at that magazine at that time).

The suggested selling price was $999.00 Its frequency response was spec'd at 20 Hz - 120 Hz, +/-3 dB. There wasn't a mention of the internal amplifier power.

Regards,
Alan
