Thanks for the info X and Zman,
It seems like the door is wide open for choices for the full ranger. I assume it does not matter if the FR is 4 ohm or 8 ohm?. I am sure like most folks, I look for the best bang for the buck, but in this case, from all the comments, I may be influenced by the higher quality(ie sensitivity, dB, frequency, etc) and hence the higher price tag.
The only caveat to the above: my old ears are not as good as they used to be, so may not be able to appreciate the higher frequencies that others may hear. tough decision!!
