We would like to test 2 of the AV15X in a 220 cubic meter room,
but please can you let us know whether it is possible to
change the Voice coil former to Nomex, Kapton or Glassfibre
to get a higher Qms? We are currently using the Focal 15″
and their high Qms (>10) make plucked bass sound extremely
tuneful and fast. I think we can live with the reduced power
handling, as the amps they will be on are anyway only 250Wrms.
Also, are the specs on your store for the 2x2ohms in series?
