Audio Nirvana 15 experience?
 

My first post here...
I have been a happy listener of AN super 8 drivers in 5.6 cabinets.
The presence and tone color are amazing. The speakers on a good recording indeed open a window into recording space and I all but "see" the performers.
I must say that one instrument that is consistently reproduced to the perfection is flute.
The bass is however a bit on the lighter side.
I have been looking at 12 or 15 drivers. There are some user opinions on these drivers, but I would like to find out more.
Has anyone listened to 15 coax?
I am mainly looking to listen to classical and jazz. 15 Alnico look good as well as 12.
I have been worried about the top register on 15 cast frame or alnico and considering coax.
I would love to hear any input regarding these.
Rest of my system is: Dared SET amp, Marantz CD player and Empire turntable.
thank you in advance!
